Screen smearing and ghosting - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Is anyone else experiencing ghosting and smearing especially at low brightness? It's very noticeable if you go into the map in Sensorly and swipe from the right and scroll up and down. Is this to be expected from amoled screens or is mine defective?

No ghosting here, but the screen does look a little funny at minimum brightness. Anything other than absolute minimum brightness looks amazing.

Ghosing?
ROLL THAT SHT, LIGHT THAT SHT. SMOKKKKE THAT SHT

Nope

Nope

Whoa! Just looked up a video and damn that's sad. Nope 0 "ghosting" here

Like Bardillion always says...." return it"
ROLL THAT SHT, LIGHT THAT SHT. SMOKKKKE THAT SHT

From what I've found its an inherent property of amoled screens but it only happens in very specific circumstances (very low brightness and black pixels quickly changing to colored ones). I see it especially when using the night theme on Reddit Sync with low brightness. I'll check with my friends note 3 tomorrow and see if she has it.

I also have the same issue on reddit is fun. Same conditions, low brightness

I discovered ghosting:

No Ghosting on Mine. How old is your Note 4? Do you have the date when the phone was manufactured? Might hint us somewhere.

Does the Nexus 6 suffer the same problem?

No ghosting here. What's a nexus 6?

No ghosting or smearing here. What's a nexus 6?

At a certain brightness, the pixels tend to turn off in presence of black colors. It's possible you're at the sweet spot where just a tiny increase in brightness is jostling between pixels turning on and off. Most likely a software / firmware issue, which Samsung can only correct if you send them a message via Social Media. Good Luck.

Hi,
Can anyone please test with this image on 10% brightness to check if there is ghosting.
Best regards

[Q] Dark spots on the screen when displaying a black image

I bought a Samsung Galaxy Note (N7000) phone about one week ago. I noticed a problem with the screen. The problem is like this:
When I am in a very dark room (and make sure my eyes have adapted to the darkness), and display a completely black image with the phone, the screen is not completely black. This is NOT the problem I want to say. The problem which bothers me is that, inside this gray screen I can notice some really black spots, just like the screen has been spattered by some black ink (but is has not).
Why is this a problem? Because even if the screen cannot be perfectly black when displaying a completely black image, it should still be uniform; but this is not the case!
This problem is similar to the one described in this web page:
http://forum.xda-developers.com/showthread.php?t=1150171
Maybe I should add that this problem never affect its performance in normal conditions. It only shows up when the environment is completely dark and when it display something really black.
So I would like to know whether this problem is caused by a defect of the phone.
A photo is attached. It was taken with a long exposure time. The photo is taken with a small Canon camera, with ISO = 200, and an exposure time of 15 seconds.
This thread has some discussion regarding the issue. I have these marks on my SGS2 screen as well; bit of a nuisance really.

Mine is pitch black as far as i can tell. However, when i run screenfilter, it dims the colors but the background (normally black) becomes a light grey.

Thanks for you information!
Did you look at the screen (when displaying a black image) in a very dark room?

All OLEDs can have this issue. I would imagine more have it than not. My old Zune HD did this. My note has it, my Infuse has it. If you are into watching black screens with nothing on them in pitch black rooms, then stay away from OLED screens. Since you really can't see this with normal use, I would say it is no big deal.
Your video issue is something else all together. That is just a boneheaded gamma setting by Samsung. Shades below 4 (with my gamma test image) aren't smoothly ramped down, they are just eliminated entirely! This gives a noticeable step from shadow details to black, which shows compression tiling that you normally wouldn't see..
I believe physical damage causes this problem..because last week when my girlfriend tossed Me my deo can it accidentally hit the screen and since then there's a huge black spot in that area thankfully though it's only visible on a pitch black image ....like the bootscreen
so no issues
This belong in Q&A
My very first Note had blotches visible even in daylight on a gray background. I had it replaced the next day under Samsung early life failure policy (first 30 days). Second phone had blotches visible only on a black background in a dark room. So did 3rd, 4th and 5th! However, the 5th Note had blotches around the edges unlike the other 4 Notes so I decided to keep it. The fact is: ALL Notes 1 have blotches. If you can't see blotches consider yourself blessed. Blotches are the only thing I hate about Note 1.

even though a lot of screens have this, Id send it back if I was you. I think its unacceptable for aproduct this expensive. It shoukd be flawless. So quickly call upon warrantee.
Next time, dont leave the store without doing an instore test, that way you can return it immediately with no questions asked

It's a bit hard to do a "dark room" test in store. After the 5th I gave up my search for a perfect screen. Until Samsung changes their AMOLED manufacturing process and improve QC there won't be "perfect" screens.

The problem is these dark spots won't appear even on the standard *#0*# screen test .
so it's kind of a non issue but what I am worried about it is, will it deteriorate in time and become an issue later on ?

Screen gamma and black levels!

Hello everyone ,i recently got a z3+ and i noticed that the black levels of the screen are pretty bad...coming from an oled display i was expecting some diffrence but not that bad...I watched some movies and in the dark scenes it is very difficult to see the picture ,everything looks the same and you cant really see the characters or the background ..its a mess especially in daylight conditions its almost unviewable.Cranking the brightness all the way up helps a lot -again in very good lighting enviroments/outside/daylight i cant see a thing in dark scenes- but then the black levels are too bad almost grey not black..
I also had a z1 compact which i dont think it was that bad, i'll try to test them side by side...
So i was wondering if a have faulty screen or something but i would like to hear your experience ...
Overall its nice screen bright with nice colours etc..but the black levels are a dissapointment in movies/videos..
Also i have disabled all screen enchanments (x-reality etc) and my white calibration is 178/162/37 RGB
Based on this review i was expecting more...
Blacks are pretty good in my opinion contrast ratio is brilliant for a ips. But this may come from you're eyes trained to a OLED screen. It's like my TV I have a lg OLED in the living room but a led in the bedroom and now I'm seeing grey instead of black :silly:

Here are some photos of my screen's blacks ...taken at 100% brightness in a 100% dark room ,all screen enchanments off, showing the same black level block picture in all 4 photos...i tried to adjust the camera exposure to make it look as close as what i was seeing ...as you can see it actualy can lit the desk under it and there is massive light bleed (if thats the correct term) out of the 4 corners in low viewing angles ,it actually creates a shape of X of light in a surface...Thats all please try it too to check out your results so as to know if i have problematic screen...

Any idea how to change screen calibration?

After November's patch we have 90Hz on all the time basically, but this also means that now the screen in dark mode is really green. Is there any way to adjust colour temperature on the Pixel 4 XL so as to correct this calibration mess? I know my S10+ can tweak colour temperature. The three available settings on Android 10 are not enough as there is no RGB adjustment.
Thanks all!
Edit: Just to be clear, rooting is not an option. Alternatively, if somebody knows where I can submit feedback to Google to resolve this horrible calibration that too would be appreciated. All grays are green. Ugh
You don't have 90 on all the time unless you've enabled developer and set it as such. The green occurs during the switching so you may want to consider enabling developer and turning on 90 all the time which can be done without root. I can say that it uses less battery than AOD (as an example) so it may be that this will fix the problem.
Unfortunately your information is outdated. 90Hz is on all the time since November patch for the Pixel 4 XL except under some limited conditions when one is not interacting with the display. I also confirmed via UFO test. The only way to get rid of the severe green tinting is to turn off smooth display which is BS. Anyway, I've decided that this product, despite its stellar camera and great physical design is unfortunately too flawed.
Battery life is poor and anxiety inducing, the display is awful (green tint, severe black crush at lower brightness settings), and even Bluetooth functionality has issues. Sure, almost all of these can be fixed by software (except battery life) but that may never happen or may take months or years to materialize. Unfortunately for $1,500 CAD that's just not good enough. There is a lot I love about the phone but this display crap is the last straw for me. Maybe Pixel 5 will do better.
Very sad and disappointed

Yup I agree. The black crush isn't severe at all and is the same as any oled at low brightness. The 2 XL was awful for black crush

There are a number of apps in the Playstore that can adjust display calibration. I used one in the early days of the Pixel 2 XL, and it worked well.
Having said that, if all greys are green, then maybe your phone is faulty and should be returned?

Interesting perspectives. I had a feeling that there may perhaps be something wrong with my device at lower brightness seeing as I cannot fathom how DisplayMate could possibly rate the Pixel 4 XL display the way they did if the display was the way mine is. If you look at my post history as well I too praised the display at one point, but my praise was (in my case) misplaced if you take into account low brightness. This was, by far, the worst OLED I've used ever, which leads me to my comment below...

Ultimately this is what I decided to do. I cannot see how this can be normal. It is truly awful. I think you cannot appreciate just how awful it is because no amount of explanation here will quite paint the picture. Since I have the S10+ and the iPhone 11 Pro, I had put them side by side just to confirm I'm not somehow going crazy and biasing my opinion and the difference was so stark that it made the Pixel 4 XL look like it was a $200 budget phone. The Pixel 4 XL has no colour detail, suffers from terrible black crush, and is completely miscalibrated with all colours at low brightness tending to green.
Last but not least, those apps you mention are all filters. There is no way outside of rooting to actually adjust the RGB balance. For this expensive of a phone, that's just not acceptable and neither is waiting for the issue to be addressed.
I may try another Pixel 4 XL just to see how it compares but I do feel that this isn't as isolated as one may think.
It's very annoying. I manually disable Smooth display in the evenings now. Hoping Google can fix this.

Yeah I don't know if you got a bad screen or what but it's amazingly better over the Pixel 2 XL other than brightness. When indoors and at similar brightness, it's very comparable to my wife's S9+.

The screen is comparable to the OnePlus 7 pro just calibrated a bit different. Any phone or any oled you can get a crappy defective unit, it your not happy swap it out.
I do wish Google gave us more options like OnePlus to adjust the white point etc, that would solve things to some extent as most people prefer or are use to different white points

That's the part that I'm not willing to bet the $1,500 on. I guess I should also be clear that if I disable smooth display - that is I go back to 60Hz - the colour calibration issue is largely resolved. The colour reproduction and black crush are still there at very low or minimum brightness, but not as bad or as prominent as with the 90Hz calibration. This also does not affect the Pixel 4 devices the same because Pixel 4 (non-XL) reverts to 60Hz for any brightness lower than ~40% even after November patch.

Agreed on the "having more options". With that said, I only care about that because the display is as bad as it is at low brightness. If I have time tonight, while I still haven't sent the phone back, I may just try to do a side-by-side comparison for you guys with the S10+ and iPhone 11 Pro. The differences are truly night and day (no pun intended). I am so, so disappointed that this is even an issue. I genuinely enjoyed the Pixel experience way more than I liked any of my Android devices so far. I stayed away from generations 1-3 because I wanted them to find their groove and finally felt that this was the time to jump in, only to be disappointed again. I will likely try another device just to see if it makes a difference and just how much, but I doubt it will be much better. Just as an FYI, in a completely dark room I run my brightness at minimum setting since it reduces glare. A good, properly calibrated OLED should still be able to produce a decent picture. The Pixel 4 XL, my Pixel 4 XL, is far from decent.
Edit: By the way, here is one really good example of it from Reddit https://camo.githubusercontent.com/...3682f45785a68422f666236646162656237642e706e67. It's not my phone, but this is the exact issue. Look at the grays - they are literally green. Here is another set of reports from Reddit as well https://www.reddit.com/r/GooglePixel/comments/ds6rd6/pixel_4_xl_screen_tint/. I am going to try to do my own photos tonight to post here.
I don't have anything like what you show in the link you posted, I'm forced on here since it turns out it doesn't change battery life much in my use. AOD uses something on the order of twice as much as an example. In any event I'm a home theater enthusiast and have spent some time calibrating, not I'm an expert time, but time enough to recognize blooming and other common display problems and I don't see that night or day at any brightness. If I did I'd have to agree, that wouldn't work for me.
Okay so I was able to reproduce this issue at will now and can say exactly how you can test for it. Basic display settings are Ambient EQ On, Ambient Display Off, Smooth Display On (90Hz enabled), Dark Mode Enabled, Night-shift Enabled, November patch though I think the same issue affects the launch software but to a lesser extent. For ease of testing, turn off auto-adjusting brightness. Once you have this set, here is what you do to see the problem yourself (note that the settings I mentioned are just what I had set when I tested this so I recommend using the same so its apples to apples comparison):
1. Make sure you have the default wallpaper set for this test since it is the easiest to detect issues with it.
2. Pull down the quick settings shade, drop the brightness slider all the way to zero, then close the quick settings.
3. Turn off the display by pressing the power button, wait maybe 5-10 seconds, then turn it back on. You will notice that the screen (at least in even a moderately lit room) is barely readable. It should now be red-shifted.
4. Pull down the quick settings again and start moving the brightness slider from 0% to 100% slowly, then repeat the process of moving the slider back and forth for a bit and note the colour changes. You will notice that the true-ish gray will be somewhere around 75% brightness or higher. Anything below this will start to red-shift quite severely (your grays will look more red/purple).
5. Set the brightness slider to 100% and close the quick settings, then swipe down to open them again.
6. Start moving the brightness slider from 100% towards zero and pay attention to the screen colour. You will notice that true gray quickly starts to degrade to greenish-gray, then quite severely green, until finally the brightness collapses severely around 10%-15% of the slider. Your display is now severely green shifted and moving the brightness slider back and forth will just show this effect switching to true gray around 70%-75% and up, and to severe green shift for anything below that.
7. Finally, drag the brightness down to zero again, then turn off your display via the power button. Turn on the display again and move the slider around again. Your display is now no longer green shifted, but it is now red-shifted. Repeating the same steps over and over will result in the same behaviour, back and forth red-shift when screen is turned off with brightness at zero, green shift when brightness is turned down after the device engaged 90Hz refresh rate and so on...
I actually recorded a video of this happening and will see how I can share it with Google.
So glad I found this post, I thought I was the only person experiencing this. do we try and exchange the device? Or wait for a software update?

I am actually talking to Google as I type this. I sent them my video and they confirmed the problem. They are escalating it now with all of the detail that I have provided so far, but they cannot tell me if or when it will be resolved at the moment. They are not stating that this is a hardware issue or an issue with my device. They believe that it is firmware/software, introduced or maybe made much worse by the November patch. I did inform them that the issue existed with the October patch, but it was made much worse with the November patch. Interestingly enough, while testing with them we confirmed that the green shift occurs even if smooth display is completely off or the smooth display is forced on. Turning off smooth display eliminates most of the red shift (though not all).
To answer the latter part of your question more specifically - this could end up being similar to the Pixel 2 XL POLED fiasco so there may not be a way for Google to fix this in software. Whether you are willing to take that risk is up to you. I am going to send my device back and am trying to get the Google dev team to update me on the progress of the issue regardless. At some point in the near future I'd like to be able to re-buy the Pixel 4 XL free of this problem.

i agree with not having time, I don't have the time to try to replicate this issue. I use my phone in my bed in the dark all the time, with a dark theme and low brightness and don't have an issue that i've noticed.

Black crush issue

Hi,
Recently I was scrolling through the zentalk forums and Flipkart reviews of the ROG 3 and came across several people complaining about black crush on the display as an issue.
Im worried about it being a widespread problem as I plan to order the phone soon and don't know whether this is due to ASUS choosing poor displays or due to some people recieving a defective phone.
I'd appreciate if those of you who have the phone could tell me about whether you notice any black crush and to what extent, also if you could please do the black crush test on youtube(by a channel called TestRaFx) and post your results for 0, 25, 50, 75 and 100% brightness that would be amazing.
(NOTE: For the test just check upto what square you can see/distinguish on each brightness level)
Ya it's there
Ya Heavy black crush while watching videos on YouTube. Especially for Dark scene it's easily visible. I have requested replacement as no refund option was available.
So much disappointed.

I'd appreciate if those of you who have the phone could tell me about whether you notice any black crush and to what extent, also if you could please do the black crush test on youtube(by a channel called TestRaFx) and post your results for 0, 25, 50, 75 and 100% brightness that would be amazing.
(NOTE: For the test just check upto what square you can see/distinguish on each brightness level)

Could you please do the black crush test at https://youtu.be/fv6T7aHsd54 and tell me your results for 0, 25, 50, 75 and 100% brightness?
How many squares can you see as grey at those brightness levels in a dark room?
Test
0% = 30
25%= 15
50%= 12
75%= 8
100%= 6
Hope this will help you.

Thank you so much, my results are currently as follows(Samsung galaxy note 4):
0%= 30
25%= inconsistent based on slight brightness discrepancies, but atleast a 7
50%= 4
75%= 3
100%= 3
It seems like you must've gotten a faulty display, no way that could be a genuine result for most units, unless Asus has purposefully provided us with bad quality displays.
May I ask what refresh rate you did the test in? Since I know that many high refresh rate screens suffer from black crush more than 60Hz displays.
Also it's interesting that at minimum brightness we have the same black crush but it gets very different during the mid ranges and then you almost catch up again at 100%. I read in android authority that the cinematic colour profile on the ROG is the most colour accurate, you could try that and see if it helps.
Mine is
0% - 25
25% - 12
50% - 9
75% -7
100% - 5
Is it okay or faulty?
Is it that bad? At what brightness should we set it to avoid this issue? Im planning to buy the phone but i think most amoled phones have this even op8pro except nubia rm5g but i dont like nubia having stucked widevine l3 and fast battery draining phone
i've seen it meh!!....it's not bothering me at all (maybe this is my 1st Amoled screen phone)....all and all the phone is an absolute beast!!....worth the buy....jumping from Redmi note 4 prime to this beast of a phone i almost shed tears!!....what a bargain

buy it if you can find the cheapest one.....mine is cheap as heck....im pretty sure the price for the global released will be mind boggling...imagine paying for retards ass price for black crush display ouchh!!...then again it's your money you do you boo!!....im satisfied with my buy...hope it'll last for 5 years max....my redmi note 4 last for almost 4 1/2 years too bad it die this years....that's when i go ballz to the walls and buy ROG im quite satisfied
Actually my order is on way rt now and i just bought the base model 865+ 12/128 and cost me only around 625 usd, which i fell is very sweet deal for the specs. I just want to know if this is normal for this unit or not be bothered to get a replacement.

Yours seems to be fine. A 5 for an amoled is average, it's not the best you can buy(that's usually Samsung) but it's good enough that you shouldn't notice too much. Also, if you want to make it better, try setting it at 60Hz and see if it makes a difference.

I think it's just the luck of the draw. You're more likely to get a non defective unit than a defective one, but again, it's really just based on luck.
As for whether it's that bad, I haven't gotten mine yet, but I don't think you'll notice it for most situations unless you're lying in bed with the lights turned off. This is assuming you get a normal unit.
As for the OnePlus, I was actually quite interested in that phone, but it has way more than just black crush. People were reporting holepunch banding and green tint on their units, so I didn't want to risk it.
Nubia is a decent choice but I don't trust their after sales service. Atleast Asus is very well known in the PC market and can be contacted with relative ease.
Sad thing is that if I didn't have the exynos versions of Samsung in my region, I probably would've gone for their s20+, but alas, they've forced my hand and I decided to take a leap of faith with the Rog instead. Here's to hoping our units are good quality.

Would you mind doing the test at https://youtu.be/fv6T7aHsd54 for me?
Just note down the lowest number at which you can distinguish a grey box from a black one at 0,25, 50, 75 and 100% brightness.
Yeah, it sucks
When I watch dark scene in Netflix, dark part seems like gray or dark green like that.
And when I turn the brightness to 0%, the display turns really strange. Only in Netflix, not other apps. But it's pretty serious problem I think

Asus actually spoke about the Netflix problem in their forums. Basically, don't use the app's inbuilt brightness slider because for some reason it changes gamma instead of brightness, so rather use the system slider from the toggle menu to change brightness.
If it's only there in Netflix then you're probably not experiencing any black crush per se, it's just that Netflix works weird on the ROG.

The test at https://youtu.be/fv6T7aHsd54
All you need to do is go to a dark room, and check upto which box you can distinguish grey from black.
Please test it at 0, 25, 50, 75 and 100% brightness, and check on both 144hz as well as 60hz.
Ok guys it took me hours finding a fix mixing colors etc but i have found a temporary solution for this
1. Download Screen Balance from Playstore(developed by QuickDoc)
2. Turn it On
3. Im on free version of the app so i am only able to try what is available
Follow settings below
Flouroscent
Strenght 90
Contrast 100
Brightness 0
Greatly Helps, thank me later lmao
So basically i think this can be fixed by a software update but need an expert calibration

Low brightness - Screen Gamma/Calibration Performance

Does anyone else feel like there's a haze/fog over the screen when the brightness is around 20% or lower?
This seems to be more noticeable on grey backgrounds. White and pure black seem perfectly fine to the eye
It's hard to try and explain?
Could it be the same issue that*plagued the 4 when it originally came out. Gamma/software calibration*needed*possibly?
It seems fairly uniform too, which makes me think gamma issue rather than panel/HW issue?
Has anyone else noticed the same?
yes, i see the same!
Yeah, we discussed a similar behavior in this thread: https://forum.xda-developers.com/pixel-5/help/colours-bit-off-everything-bit-beige-t4179867
For me I do see this "fog" brownish tint in every brightness situation....

Not the same thing. You're on about color profiles in that thread. This is more like a contrast issue at lower brightness levels
Well... than i have both... there’s fog with loss of contrast and there is a „warm“ color calibration.
My P3 shows black areas where the P5 is grey. Plus, white is minimal brownish so i loose contrast.
I come from a Pixel 2 XL with the black crush. In terms of contrast at low brightness levels, the Pixel 5 is far superior.
Undecided whether to keep it or not.
Grey's look really weird compared to my S10e. Nice and dark on the S10 and really light/pale on the Pixel?
Here's a capture of screen uniformity too
