Slight screen flicker?

I have a nook color, I was wondering if anyone notices a very slight screen flicker like a low refresh rate? Most people would not notice. It doesn't bother me much but I wanted to see if its normal. I notice it most on a dark grey background at 50 percent or lower brightness.

Yes! finally someone that notices it! I have been posting this on other forums. I notice it too on dark backgrounds with about 20-40% brightness, Not sure if it can ever be fixed with an update, but it is sometimes annoying, although not highly noticeable.

I have worked with computer enough that I can tell the refresh rate of a crt just by looking at it. If its normal I am not to worried I justed wanted to know if it was defective because ill switch it out before I root it.

I get the same thing, very noticeable when you are changing the brightness setting. I use the lowest brightness to read an eBook, and I can really notice the flicker when I lower the brightness, but I can notice it when I get back to the reading screen.

I see it on darker images...its so subtle I ignore it.

I still have mine stock... but I see it as well.
Anyone that has loaded any other apps notice it in those apps? i.e. does it flicker noticably in Angry Birds? or other apps?
thanks.

I wonder if it being an IPS screen has anything to do with it. It doesnt bother me to much but causes more eye strain than reading from my htc g2. You would think they would make sure an ebook reader doesnt flicker. oh well i can deal with it.

It's not the screen, per se, but the LED's that are lighting it up. From what I've read, LED's can't vary output with respect to voltage (they're not dimmable), so you have to pulse them very fast to change the output. I assume that the lower the "level" the more the LED is off vs. on, hence the flicker.
Dang I can't post links yet...
Go to Wikipedia, and look for :
/wiki/Backlight#Flicker_due_to_backlight_dimming
I'm pretty sensitive to this, but haven't noticed it on my iPad, but apparently it does it as well. I was wondering why the stock lowest brightness levels were so friggin' bright - probably at the threshold of flicker. You can dim more in a browser or ebook app, which is where I see reports of flicker.

While you can dim an LED by limiting the current (either via inline resistors or with constant current drivers), you can only do so to a degree. Below a certain current, they will simply not light even though the current goes through the LED. On high performance LED's this is still at a pretty bright level. So instead you use PWM (Pulse Width Modulation) and vary the duty cycle to brighten and dim the LED. As the PWM is at a fixed frequency, with more or less of the cycle being lit or unlit, once the unlit portion becomes substantially longer than the Lit part, you can detect the "Flicker" if you are sensitive to it. This is usually particularly noticeable in the "corner of the eye" if you pan you vision across the area and the device gets paned across you field of vision.
This is done on all the new LED tail lights on cars as well and I hate seeing them at night, when they are almost making me nauseous from the flicker.

Good info thanks. Makes sense but wonder why I don't notice on my led backlit netbook. Guess every screen is different.

yea I really wish there was an update to fix this, but i guess it's just the screen, funny how I have never noticed this on any LCD screen I have ever had from computer to TV

three nook colors - my experience with flicker
My first nookColor had screen flicker, also a mind of its own with phantom taps. Nook #2. Did not have noticeable screen flicker but did have a handful of stuck pixels. Took it back and picked up #3. No stuck pixels, but I've got screen flicker on dark colors. Find it strange that nook #2 didn't have te problem with the flicker. I don't like the flicker at all but think it may be timento live with it.

flicker
Has any one returned a flikering nook color and gotten a better one in return?

Hello, I am having a similar problem with angry birds. My screen sometimes will flash different colors and today the screen stayed completely red for 2 or 3 seconds while playing the game. But other than that I love the rooted nook color. Maybe the graphics chip is not powerful enough for this game.

Firmware update
What you described with angry birds is not the problem I am having. Mine is screen flicker. My eye can basically detect the refresh rate with low brightness or in darker colors.
Tried to change it out. Would say that Best Buy is much easier to exchange things at than Barnes & Noble. Eventually they switched mine out and the new one had a dead pixel. They then let me open two more in store in the store all had dead pixels, so did their display model. All presented in the lower right hand corner of the screen. Would be covered up by the black menu bar normally, but visible when the black menu bar goes away.
Anyway I kept my flickering nook, and talked to someone at Barnes and Noble tech support on the phone. He told me the dead pixels were new to him, but they knew about screen flicker issues. He said they would be releasing a firmware update to address this and other problems very soon.
Just wanted to note that none of these nook colors were rooted.

Yes, same here, I have that on my Witstech A81 (resistive screen) too, more noticeable when the battery level drops. Never noticed this problem on my iPhones or iPad though...can't be Android related can it?

Thanks. I can see the flicker too on gray screens. I have no other issues though (minus a tiny, tiny bit of give on the bottom bezel). I'll wait and hope it gets fixed in an update. I don't have a lot of time to keep exchanging a good unit.

If it is a known issue and a firmware fix is planed, then I am content with my rooted nook. Thanks for this thread.

I took mine back to B&N today to see if replacing it would fix it. Both store displays didn't have any flicker.
They opened two different nooks and they did the same flickering thing.
So I called Nook technical support. He put me on hold for about 5 minutes. He said he checked about 5 nooks and they all flickered. But he hadn't noticed it before.
So, he will put a ticket into the development team to have it looked at.
So, another confirmation that Nook tech support is aware and looking into it.

My first Nook did not display this behavior. I returned it due to creaking issues, and the replacement did display screen flicker.
I'm hoping it's a firmware issue and not a hardware one!
Currently not a big deal though...

My Samsung Focus S full review with comparisons to Focus! (Videos will come)

NOT DONE YET but here's my pretty long review of the Samsung Focus S and comparing it to the original Samsung Focus. I tried to go over every single thing I could possibly think of and hopefully someone appreciates it! Post any questions you have and I hope others will post their experiences as well.
Still in progress: CPU benchmarks, 4G speed tests, camera review and examples, battery life, some videos.
Performance
CPU - Still working on this!
With the faster processor loading times are definitely shorter on apps and games. You'll notice that XBOX Live and Marketplace both open a second quicker. Also you will see better performance within apps, with less lagging and faster scrolling. Runs great and I'm loving the performance boost.
(Benchmarks coming soon)
GPU
The upgraded GPU is great! I tested Super Mario Bros 3 on an NES emulator and was getting 48-55 fps WITH sound and 60 fps without! Plays near perfectly.
(Video coming soon)
4G - Still working on this!
So far I haven't noticed much of a speed increase. I live in a 4G covered area and I get 5 bars at home. I will do some more studying and speed testing and get back to this.
Internet sharing is listed on the settings page but when attempting to turn it on you get a message about signing up for an appropriate tethering plan. If you reload internet sharing through provision xml it will get rid of the message.
RAM
A few apps report it as having 354MB of RAM. They report the Focus as having 481mb. Both have 512MB and the 'missing' RAM is not useable because it's dedicated to the GPU. You won't even know it's gone though and the GPU's increased performance is worth it. I tried a test where I launched Fruit Ninja, Hydro Thunder GO, Sonic The Hedgehog Episode 1, and Twin Blades and checked the RAM usage. All games were in the middle of gameplay (not at the start screen) and dehydrate on pause was disabled allowing them to all stay where they were at in the game. My peak RAM usage reported as only 31MB.
GPS & WiFi
I tried them and they work just as they should. Still unable to connect to hidden WiFi networks though.
Battery - Still working on this!
I still need to go through a few more power cycles to know what it's like for sure. I'm a heavy user and I'm on my phone all day long so it does not last me the whole day. I'll post more info once I have a better idea.
Keyboard
Right now there is an issue with the keyboard. Many people think the keyboard is lagging. However I think it's just the keyboard tap sounds that are delayed. It makes it really annoying to type because you THINK it's lagging. To me the letters come up just as fast as I type them and when you turn off the sound it doesn't seem delayed in the slightest. It should only take a simple update to fix that.
Hardware
This phone is much thinner and lighter than the Focus. It does not feel too big in hand and I think it's a perfect size. After only using it for the first few hours, my Focus already felt like a brick compared to it. When pictures of the Focus S first came out I didn't like the aesthetics of the textured backplate but it feels nice in hand and adds some much needed grip. I wished the bezel around the around of the phone was less pronounced and it looked more like the original Focus in that aspect. At first it kinda feels cheapish because it is plastic and extremely light but I've gotten over that and no longer feel that way. The device feels solid. The backplate on it is the thinnest piece of plactic ever and it will bend and can easily break. Not extremely difficult to take off and I actually like it better than the Focus' which I thought was a pain to take off because I felt like I was gonna break the phone while doing so. A nice little added touch is that when you tap on a capacitive button it will dim the button's backlight a little bit.
Screen
The bigger screen size is great but my feelings about this SAMOLED+ display are mixed. I have a huge problem with the display and that is a ghosting/blurring issue. Whenever you are scrolling through lists the texts is blurry and once you stop you can see it 'snap' into focus again. It's also noticeable during animations such as launching XBOX Live. This might not bother some but to me I find it highly annoying! I don't experience it on my Focusat all. May be my biggest issue with the phone.
Another issue with the display is the brightness. I guess Samsung wanted to preserve as much battery life as possible and they made the lowest brightness of the screen extremely LOW. But let me explain, the maximum brightness is plenty bright, the problem is just the minimum brightness level. When comparing the Focus and Focus S both on the highest setting; the Focus S is definitely brighter, and on the lowest setting: the Focus S is way dimmer. The issue is what they have set for the lowest screen brightness, it's just too damn low! You will need to keep your phone on atleast medium brightness, low is pretty much unuseable and that's not even talking about during outside use. This also affects the automatic setting as well and it will be way too low most of the time. I don't think the brightness issue is a big deal though because:
1- It can easily be fixed with an update.
2- I put together a file you can deploy to your unlocked phone that will edit the registry to increase the brightness of the low setting. It will make the low setting similar to the brightness of the Focus' low setting. The only issue is it will NOT fix the automatic setting and that will continue to be way too dim.
Also there is another new setting that will mess up your brightness levels. Samsung added a page to settings called Extra Settings that will bring up the option to turn on/off the following:
Auto Display Intensity
Key Vibration Feedback
Echo Cancellation
Auto Display Intensity needs to be turned OFF. With it on you will notice the brightness constantly flickering, especially on a light background. It's extremely annoying. The problem though is you can turn it off but the setting doesn't want to stick! If you soft reset your phone it will turn back on and you'll need to switch it off again. Trust me you'll want to... I find it horrible. The did release an update for Extra Settings in the marketplace but it did not solve this issue. Atleast we know it's a simple app update through the marketplace though.
I think the Super AMOLED Plus' colors look a little fake and more saturated. I don't think it's too terrible though. The Focus' colors may be more true, but during movie playback I like how the Focus S' colors looked. Daylight use is fine as long as your on atleast medium brightness. Viewing angles are pretty good.
One last thing about the display. I did experience some weird flickering on my device the second day I had it. It hasn't happened since then but I don't think it's a good sign. I did get to take a video of it. It's hard to see it in the video because it kinda looks like distortion from filming but look closely, all those dark flickering bands you see are happening on the screen.
I don't know if it will happen again but if anyone else has experienced it let me know!
Camera - Still working on this!
Well this camera is definitely quicker than the Focus' and when holding each phones in the same spot, the Focus S will give you a greater viewing range and you'll be able to see more in the frame. But other than that I don't think the camera is much of an improvement on the Focus'. I'm still working on taking examples on both phones for a comparison. The camera offers no new settings (such as HTC's burst and panorama modes). I tested the LED on both the Focus S and the Focus in the dark and I think the Focus' LED is slightly brighter but it's pretty close and hard to tell. Overall I'm don't think I'm impressed with the camera.
I haven't taken any videos with the camera yet and will get to that later.
Front Facing Camera
It's there and it works! Quality is not great of course... standard poor webcam-type quality. Tango works great though and hopefully Skype will be released soon. Ability to use your phone as a mirror is nice. Pictures taken with the front facing cam are reversed after being taken, which I think is kinda annoying.
Storage
16GB actually meanings 14.07GB total. After a fresh install Zune will show you that 1GB is used with 12.53GB free. If you go into Zune's setting and lower reserved space to 0% it will give you 335.78MB used and 13.20GB free. It was depressing finding out the Focus S would only have 16GB instead of 32GB and no MicroSD slot. I never used the MicroSD slot in my Focus in fear of a random hard reset so 16GB is still an upgrade for me. I kept some music on my Focus (around 2 or 3GB) but no movies (never had space for them). My Focus was filled completely so it's nice to have some breathing room now. Even though it's not ideal I think 16GB is sufficient enough for now.
Speakers
First of all the speaker on the back is at the bottom of the phone. I think this is a poor position for it. While holding the phone your hand will tend to cover it and distort the sound. The loudspeaker is also not as loud as the Focus and doesn't sound as good. The sound with headphones plugged in was disappointing. Compared to the Focus it sounded very flat. The Focus has more bass and music sounds much better on it. Samsung doesn't offer any sort of equalizer app. Headphone volume also doesn't get as loud.
Microphone
I did a test where I recorded myself talking on both the Focus S and the Focus at the same time. The Focus S had a noticeable static in the background while the Focus' recording did not.
MicroUSB
The MicroUSB port is at the bottom now. It seems like it makes more sense to have it at the bottom. No little door covering it but I don't miss it. It's low profile and hassle free. If you keep your phone in a cup holder or so while driving it may be awkward to have it plugged in now. But it is easier to talk on the phone with it plugged in at the bottom. The moved it to the bottom but you know Samsung won't release a dock for this phone, it's a shame.
Buttons
The buttons on the phone feel really good, easy, and very pressable!
Call quality
So far I haven't had any dropped calls. Seems pretty decent in that regard. BUT I've been told there is an obvious decrease in sound quality on the other end since getting my new phone. Multiple times I've been told that the other person couldn't hear me at all. It seems to happen when I have the phone about 4-5 inches from my mouth (for example when I'm laying down and have the phone on pillow). The in-call volume is still too low just like the Focus. I wish I was able to hold the phone more than a few inches away from my head and still hear it. Speakerphone is pretty mediocre and not great. I'm disappointed with the microphone and speakers on this phone.
Homebrew
The current registry editors out there do not work. Only way to edit registry is with using a provisioning xml. I have used this method to enable the instant resume hack and to increase the brightness when on the low setting. I tried to change accent colors using this method but so far have been unsuccessful.
Interop unlock works but doesn't. You are able to install the unlock, removing your sideload limit and getting rid 0x81030120 error when deploying interop apps. BUT the apps you deploy won't work. They will either fail to start or their functions just won't work.
The diagnosis app is installed the same way as before (dialing ##634#). It is version 0923. Not all the codes are the same though! *#77284# (tethering) and *#9908# (GPRS Manager) still work. Some other ones that I tried like Auto SIM Configure do not.
USB tethering is possible! Similar to tethering on the Focus but an extra step is need as discovered by dbrandusa. See instructions here:
http://forum.xda-developers.com/showpost.php?p=19175627&postcount=8
Overall
Pros
New CPU/GPU offers a definite increase in speed and power. App launching, app performance, gaming, HTML5 all benefit from it
Bigger screen size and yet thinner and lighter, perfectly sized device in my opinion
Bigger storage capacity (but no MicroSD)
4G capable (but don't expect a significant speed increase)
Has front facing camera (even though quality is nothing special)
Easy to press buttons
Cons
SAMOLED+ display produces very annoying ghosting/blurring. Also potential flicker issue
Microphone has some static and issues with other people not hearing you during the call
Speakers are not as loud as Focus' and sound flat
Camera is not much of an improvement
Headphone quality is much worse than Focus' (needs more bass)
Headphone cable controls do not work anymore (Unsure if it's an issue with the aux design or a software issue)
Delayed keyboard tap bug *can be fixed with update*
Extremely low brightness when on low or automatic settings. Annoying "auto intensity display" setting that turns itself on after each soft reset *can be fixed with update*
I really want to love this device. Looking at it sitting there I just want to grab it and play with it much more than my Focus. But I think I was happier with it until I starting comparing it side by side with my Focus. At that point I started seeing it's flaws. I love the faster CPU & GPU, dimensions, screen size, storage upgrade, having a front facing camera, but the biggest dealbreakers for me are the ghosting on the display, poor headphone sound quality, and in-call microphone issues. I will definitely be exchanging it for a HTC Titan on the 20th and I'll see how I feel about that device. If I decide it's too big, the pixel density is too low, or some other major issue I will come back to the Focus S. If you have a Focus or other first generation device and debating between upgrading to the Focus S or waiting to see what is coming (from Nokia and such): just ask yourself are you content with your current storage capacity and screen size? Do you really need your apps to load a second earlier? Do you HAVE to have a front facing camera? If you do need those things NOW and the Titan is too big of a device for you than I think it'll be worth the upgrade. If you do get one you'll just have to be patient for the bug fixes though. If it's your first Windows Phone you'll probably be content with it as long as you turn the brightness up.

Does it seem faster?

Absolutely, in my opinion.

On another side note, it's crazy how different the AT&T rep was today compared with last year. Maybe it was just that particular store, but the rep that sold it to me was blown away by it's responsiveness and decided to show it off to 3 other reps before handing it over to me. They only had two in stock (one was on display)...so I got lucky. But, I remember last year...and the rep that sold me the focus had spent some time trying to sell me an Android or iPhone even after he knew I was there for the Focus. So, is it a change in AT&T training for WP7, or that the product speaks for itself?

i went to an at&t store today, and the focus S and focus flash were sitting in a lonely corner the store was packed but not a single other person besides me was looking at it, haha

could you take some photo samples? I wonder if its the same lens from the GS2, that has pretty high praise for its camera

does your unit overheat when running graphic intensive games? I also noticed that autocontrast is quite poor
have you experienced this?

How does the quality of both the primary camera and front facing camera seem to other phones you've used in the past?

I picked up a Focus S today - like the OP said, it and the Flash were tucked away in the corner of the store. I use an iPhone, but was looking to upgrade an Android phone on our plan and have been interested in trying W7 Phone. The store had exactly one Focus S in stock.
First impression - really light, almost freakishly so. Fairly thin - a little lip at the bottom makes it easier to hold. Screen changes and app loading is very snappy. Screen is terrific.
One nice touch - bloatware, and there is some, is very easily removed. It's much closer to the iPhone where there is zero bloatware as opposed to an Android phone where you literally have to root the thing to remove the nonsense. (An Motorola Android phone on the ATT network might have upwards of two dozen preinstalled, unremovable apps.)
Can't really comment on anything else given that I'm about six hours into this Windows Phone thing.

I just picked up my first windows phone, focus s, i notice that when you lay it on its back, you can possibly scratch up the camera lense/cover over time....why would they design it to stick out like that?

Focus S vs. Focus
Here's some pics I took of Focus S vs Focus. It's hard to get a true feel of the difference b/w the two in regards to the screen, but I think a few of these pics are able to show it.

That would be the pen-tile matrix of the Super AMOLED display.. it has fewer sub-pixels than the Super AMOLED Plus display in the Focus S.
Notice how the text is blurrier in the Focus pictures? (look at the marketplace picture in particular)
here's a good comparison (not the focus.. but galaxy S and S II.. which use the same kind of screen as the focus and the focus S respectively)

I think thay should made the Focus S a bit more like the original Focus. in my opinion the design of the original Focus is great.
Anyway a good phone

Were there any cases for Focus S in stores? I do not see any listed on AT&T site and I can not buy a phone without a case.

The only thing that irks me is the location of the USB port. While in car I keep my phone docked and having the car charger plugged in on top makes my phone physically unstable.

None of you has used a SGS2? The Focus S is almost a direct external copy of the international/AT&T version. There's a reason Samsung has sold as many as they have in so short a time. Far superior to the Onmia/Focus/Flash.

No, there were no cases in stock and none listed in the ATT system.

Thought I was on reddit for a second here, with the AMA =D

Trust me, this thing is diesel...reception is ridiculous...im loving how fast 4g is..if u liked ur focus, this is for you, as it's a much bigger upgrade than I had anticipated..i mean, those who have wp7 already know how fluid the os was/is with the 1st generation phones...so it was hard to imagine that they could run noticeably faster....well, they can. And, it's noticeable

Nice!! I took my brother to get a new phone yesterday and after him playing with the iphone, HTC Vivid (which is actually REALLY nice) and the Focus S, he finally settled on the Focus S. He asked a few pointed questions about each and myself and the rep gave him honest answers without much bias (despite both the rep and already owning the HD7 and HD7S). My brother makes up his own mind regardless of input and was really impressed with overall look of the OS and how smooth it was. And the phone was SO thin he said with such a huge screen!! It almost made me switch back to ATT, but figured I'd wait for what I've been waiting on a little longer (the Titan), before I decide. Overall impressions though were it's a really great phone, buttons are perfect in all aspects and it's the lightest and thinnest 4.3 in device out. If you dont want the Titan, get the Focus S for sure.

Burn in concerns?

Until now, I've actively avoided AMOLED screens, in part due to the ability to get screen burn in. I'm still not thrilled about it, but it seems no flagship has LCD anymore and I'll have to make the trade-off.
I get some of the benefits of AMOLED, but this surprised me a bit to find on a gaming phone since games have static images (scores, gauges, maps, icons, etc). I also know that running an AMOLED at full brightness increases the burn in risk, but I'll be using this daily in bright sunlight and will need the screen fairly bright.
So what's the current expectation for the ROG 2 screen when it comes to that? Any word on if burn in will be much of a risk anymore? Would the Asus U.S. Warranty cover that, and for how long?

Burn in is probably a far smaller issue than you'd think. I've used AMOLED displays since 2010 on several different devices and never had an issue. It does happen but probably far less common than you'd think.

The only AMOLED device I've had that experienced burn in was a Samsung Galaxy Note 5, which I used for many years and was my daily phone up until I received this ROG Phone 2 a week ago. Even then, I didn't notice the burn in on it until about a year ago, and only found it by deliberately looking for it by using an app to show full screen solid colors. Even to this day I don't notice the burn in on that Note 5 during normal use. The entire time I used the Note 5 I had the brightness set to max with adaptive brightness on.

Especially with gestures replacing the static nav bar. Those would burn in over time. But the status bar stays pretty active, so there shouldn't be much chance their either

My wife prefers the Notes and every one of hers got burn in. Her last one was the S7 (due to the N7 fiasco), and I noticed burn in within a year. She rarely has the brightness cranked, which is part of why I'm still on the fence.

Now that I have android auto radios in all my cars I don't expect to get much burn in from now on, but my note 8 always has Waze ghosted on the screen.

As others have mentioned before the benefits of Amoled screens far out take the LCD ones in many areas. For example one thing I hated about LCD screens because of the technology was the uneven side/bottom light spots which can be easily seen in a dark room and were very annoying to see.
Regarding Burn in, there is an easy way to avoid it in the long run by using gestures for system navigation and in regards of the status bar you can use any 3rd party app which can hide the status bar. Personally I use "Immersive manager" app to hide the status bar on ASUS launcher and in some apps which I don't like to see it in, and so because of the switch between the home screen and apps, the status bar isn't static and for that reason i doubt burn in will be an issue.

I would caution about the "Always-On Display" option of the Asus Rog Phone 2. If you go to bed and leave the phone face-up (proximity sensor not covered) then it will leave the static clock graphics up all night. I could imagine that being burned in over time.

I was watching a review video on it yesterday and it showed what looked like the AOD clock shifting (it was a short cutaway shot, so could be mistaken). I will keep an eye on it, though, to see if it does move.

Just like you, I avoid AMOLED screens. I had an S3, burn ins from web browser... I watch YouTube a lot. I am not sure the AMOLED screen is for me. It became difficult to choose a phone.

Just enable Dark Mode within YouTube and assuming you watch in full screen mode, you should not have any problems. I personally run YT for about 3-4 hours everyday: the phone sits below my monitor at work and I have earphones on. Glance at the screen from time to time, since what I usually do doesn't require full concentration at most times. Never faced burn in from YouTube.
I did face some issues on Quora though, but that was with a Moto G4+ and seemed to be temporary. The logo bar on top stayed for a while, ghosting as I used other apps but went away in a few minutes after I left the page.

Amoled screens burn-in is much less likely to happen now due to advancement in screen technology and also software implementation to counter it.
There used to be a time when averagely 30-40% of screens had a form of burn-in or another.
Unless you're unfortunate to get a defective screen, I doubt if burn-in will be an issue for you.
I have a 2-year old Huawei Mate 10 Pro which I've used so much and mostly outside (full screen brightness), but there isn't a sign of burn-in on it.
Though it would be important to know the screen manufacturer for the ROG II as not only you can have an idea of the quality but also aesthetics.

I already have some lines and screen uneveness in lower brightness and mostly gray color, i wouldnt call them burn-ins but the device screen is diffinitely defective as it's only 4 weeks old and the screen was uneven from the beginning
Btw the quality and sharpness of colors is nowhere close to my father's galaxy a40 so either my device is a complete defect or the screen is just not that high-end stuff
And lets not forget the rediculous issue of getting red tine when lowering the brightness it sometimes drives me crazy, still the 120hz refresh rate is so great i cant think about any other phone!

Red tint on dark grey ie dark theme on brightness below 50%

There is a noticeable red tint on dark grey color everywhere while the brightness slider is set in range of 0-49%. Effect is more pronounced while using 120hz refresh rate and less while using other modes. 50% and above and the tint just disappears.
Does anybody suffers with the same issue? This is indian variant of the phone.
Attached image can be used for testing.

This seems to be a problem with many ROG 2 owners. The Red tint is massive at low brightness. And yes, this is a screen problem not a software issue.
Better try replacing the unit. But there is no guarantee new phone won't have the same problem as many people are reporting this issue.
I think maybe Asus is buying cheaper display from some other manufacturer, not Samsung. Here is a similar complaint thread on Asus forums -
https://zentalk.asus.com/en/discussion/11085/display-red-tint-issue-on-my-rog-2
And if it very troublesome for you, simply return it, ask for refund and buy some other device.

I will probably do that but samsung has that stupid hole. I sold my op 7 pro for this.
But 1 thing that is interesting is at 60hz the red tint is visible at 0-10% range. And the higher the refresh rate the more brightness range it covers like at 120hz its visible at 0-40% range. At 50% nothing of such sort is visible at any refresh rate.
It mostly has to do with that 1ms gtg ie grey to grey response time at high refresh rate. And yes all units will have that issue maybe not at 60hz but definitely at 120hz.
Lets see if asus has any response. I still have my return window left.

And now you know why others don't have 120Hz AMOLED panels, and why reviewers complain about the minimum brightness being too bright. Asus tried to mitigate these issues because the panels are only acceptable above a certain brightness.

I have an Indian unit and have the red tint. I don't have an issue as i keep my screen at 50% brightness. Hope in Android 10 apps use black instead of dark grey for the dark mode

Reality is that most apps including google ones are going the way of dark grey background, not pure black.
Also always 50% brightness? Don't you turn it down in room with no lights or low lights?

You sold OP7 Pro for this? Seriously bro? I mean unless one is a gaming fanatic, ROG doesn't make sense for someone who wants a overall great experience. It was evident that Asus has cut corners at many places when they priced it so low.
Even if it's 60Hz, red tint shouldn't be there. It's an example of not a good display.

OP7 Pro had its issues, I bought it on first sale. camera focus was not good, camera output was soft around corners while clicking text/documents for sharing. the screen though gorgeous looking was actually hard to use. i can recall a particular issue - i use phone pe and the menu for edit beneficiary was just in the screen space where it started to become edge and it required multiple touch to activate it.
actually rog 2 feels more premium in hand and the weight distribution is quite good as compared to op7 pro, it was top heavy. i have large hands so actual phone size was not the issue with either op7 pro or rog 2.
if one can ignore this red tint issue almost every aspect is better than op7 pro. screen above 50% brightness( which is actually not 50% screen brightness output, its just 50% slider) hdr in video playback works very well, its a quite brighter than op7 pro. Sharpness is less but only apparent on close viewing. Sound quality is better on speakers and louder too. Screen smoothness is much better. gets less hot then op7 pro, Cyber hunter on full was 47-48 on op7 pro, its 44-45 on rog ii. and the battery life is way better. There are much differences to be pointed out but the thread will grow.
Though the phone might not look professional in a meeting and i don't think it will receive timely android updates. But as a usable device i find this better than op 7 pro. If the grey management was not an issue this would have been almost unbeatable in its category and even in a higher category. op7 pro costed me 51.5k after bank discount, this costed 34k after bank discount.

Agree. Said just a hope. The objective of dark mode is also to take advantage of amoled which is not met by grey. Hoping common sense prevails.
I hardly use the mobile in low light, if i do, i dont turn the brightness down

If you wanna see the issue:
1) go to a dark room or in a room with almost no light.
2) add "Screen Frequency" toggle in the status bar, and lower the status bar to show the toggles;
3) lower the brightness above 40-50%;
4) use the toggle to swap frequency from 60Hz, 90Hz and 120Hz.
You will notice the colour of the status bar itself changes… it's like is 80%grey and 20%red on 60Hz; 90%grey and 10%red on 90Hz, 50%grey and 50% red on 120Hz (it's like the status bar is dark-brown coloured).
And, then again, increase slowly the brightness: the status bar will be "magically" turn back to its natural color, dark grey.
This is a big issue for a smartphone which costs about 960American dollars here in Italy! I'm thinking about to return it...

This means international version suffers with the same issue. What they have done to achieve such high refresh rates and such low response times must be the issue. Now if someone from asus can confirm if this tinting can be fixed via software update or not that will be the main factor for either keeping or returning the phone. The issue is already raised in zentalk forum and i have also commented there and the mod also has accepted the issue in his demo unit.

It's so minor I've literally never noticed it (until using your test image just now) and I've been using this phone for almost a month now. I'm filing this under not an issue for me.

Not an issue for me. My brightness is pretty much always set to 50% and 90hz - never even noticed it. If you're running brightness down around 20% then you're either pretending to be on an Ethiopian diet, or you have an issue with over sensitivity of your retinas and should get it checked out asap

This only affect night time usage with lights out or in low lit environments where you will keep your screen brightness low. Daytime usage is perfectly fine as 50% slider is not actually 50% screen brightness. So slider % remains high during day.

Its clearly mentioned that its a non issue with brightness slider in range 50% and above. So you wouldn't notice it.
And by the way if you are using that high of brightness in low lit or lights out environment then maybe you have less sensitive retina and maybe get it checked.
This will only affect people who use this for night time reading and naturally dim the screen to read comfortably. If people use normal day brightness at night this will be a non issue for them.
The main point is is this a hardware or a software issue. And i have already hypothesized why this might be happening. You can read the posts above.

I don't think I would ever find myself in a pitch black room with just my phone and no other background light of any sort. I'm not that kinda guy
If you head over to the Asus forum, this is not a new issue. Asus have declared the reddish tint is normal behaviour of the screen at high Hz, so its hardware, not software, and operating as it should. Every handset will be exactly the same. If it bothers you too much, then maybe look at the Nubia Red 3S or Xiaomi Blackshark 2 instead. For me, its a non issue as like you said, i never drop below 50% brightness, and my retinas are poor, so I would never see it.. :fingers-crossed:

I always thought that xda subscribers were above fanboy-ism...

We are all fans of something! :laugh:
This is my first Asus phone, and I'm coming from a long line of samsungs (the latest being the Note10+) and for what I do with the ROG2, its performance creams anything Samsung has ever produced.. so, when a negligible issue like red tint (don't forget Samsung had blue, sony had red also in the past) I'm willing to forgive it because 99% of the time it doesnt affect me. If you call that fanboy-ism, then so be it..

Looks like, red tint in the display, issue is widespread in most of the ROG 2 phones .
Asus has confirmed the same, but refused to say, if it is a SW issue or HW issue.

Question Screen shows a greenish tint

Hello.
My Note 10 Pro screen has a greenish tint that can get quite annoying. It mostly shows on dark grey colors and on the top and botton of the screen, it's less strong on the center. I tried to correct it modifying the screen settings color correction (this much) but this only somewhat improved it but it didn't get rid of it.
With full brightness it's not that strong, if the image has greys you can tell it's a bit greenish but it's not very noticeable unless you put it side by side with another screen.
I tried to take a photo but it's hard to tell the difference:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
On low brightness it's very noticeable if the image has grey colors and you are using the 120Hz mode which makes it notably worse (60Hz mode still shows the green tint, but not was much).
(On this image I'm using minimun brightness)
Also if you use the 120Hz mode and you lower the brightness to minimun some wrong violet colors appear on the top and bottom of the screen, like the photos show:
These weird violet colors do not appear on 60Hz mode.
Is anyone else having this problem? I wonder if I got a bad OLED or instead just the Redmi Note 10 Pro's screen is not good overall. I could live with 60Hz mode but even then the colors still look a bit greenish and I didn't bought this phone for not using the 120Hz...
What do you think? Is it worth getting a replacement?

i think it is a hardware issue
it happened before with amoled screens
you should go to get a replacement

Most of the people are facing this tint issue in redmi note 10 pro. I have seen many people complaining that they are facing purple tint on 120hz mode. Well i haven't seen it by myself cause haven't received my phone yet. And now after hearing all this i am afraid what if my device start doing this tint thing. I hope xiaomi fix it asab with some updates

On my device when i overclock screen from 60 to 84hz green tint appear also. This is most likely hardware problem and not software. I was thinking to buy 10 pro :/

What device do you have? Redmi note 10?

I have found that using the colors on "Automatic" instead of "Standard" helps with the greenish tint. I usually use standard because it's more faithful to the original colors and the automatic commonly gives a blueish tone (and it does here too) but this blue tone helps masking the greenish tint at 60Hz, so I find it better. On 120Hz it's not enough and it still looks too greenish at low brightness.

Same here with the purple tint. It's not a deal breaker though, once you know it and... don't watch movies in the dark (which is bad for your eyes anyway)... What might be one if you're after the 120Hz screen is that I think it doesn't adapt to the context as expected (120Hz in Miui even when nothing updates on screen, 60Hz in some fast games... Would have expected the opposite).
Still an awesome phone for that price. Didn't miss my Mix 3 anymore! (BTW I'll "sell" that one, if someone is interested - along with it's new screen that doesn't go on, motherboard is OK, selling it as-is, i.e. open and waiting for a repair. More details soon on Mix 3 forum).

I do have this issue btw did you get it replaced?

thank god my 10 pro seems to be fine... no green or purple tint or any other issues

Those photos are quite informative. However, we have been here many times with (am)oled devices. Unlike IPS, amoled are very susceptible to slight alteration of electricity that powers it. The less it gets, the more likely colour deviations are to occur. The solution is most likely to stay on standard settings until Xiaomi figures out or "refines" what's best configuration for every each screen it installed using update. Keeping the device in mid to high brightness usually helps since it pumps up higher electricity, thus more accurate the colours would show.

I didn't, I didn't want to go through the hassle of getting a replacement, less when I could get another one with the same problem and anyway the problem only shows on 120Hz at low brightness so it's not like the phone is unusable... What I do is enable 120Hz on the morning and disable it at night which is when I use low brightness, it's a bit annoying but it's working for me until now, and tbh some days I forget about enabling it and I go through the day without noticing I'm using 60Hz. The rest of the phone works fine so whatever, I still consider it good for the money.
I said on my first post that I noticed the green tint even on 60Hz but I have been comparing it with other amoled smartphones without being able to notice a difference so I think this is just how this screen technology works and I was just too used to my previous LCD IPS colors. After using my phone for some days I got used to it and don't notice it anymore except when I use 120Hz and low brightness. I also switched back to Standard colors since Automatic was just too unrealistic.

I'm facing the same issue
I have a greenish tint,
I have DOT OS installed so, I will have to revert to MIUI and stock recovery right?
Do I have to lock the bootlaoder too? cause I heard unlocking bootloader doesn't voids warranty. How can I revert back any help?
