i haven't seen any complaints about ghosting so it may just be my phone but i have it really bad.
it's very visible when i scroll through my home screens because i have a near black background and use the red and white data widget.
it also makes text and such look horrid when i scroll through menus or web pages

You probably have the brightness set extremely high or extremely low.
Whenever CM7 comes out for the D3, you can try adjusting render settings to improve the overall gamma of the screen. I'm guessing you're just more sensitive than most to a high-persistence screen, unless you have found a way to monkey with your refresh rate

i've got a friend who has the same phone so i'll see if his is the same.
i haven't messed with the screen settings at all and have it set to auto brightness.
my last phone was the Nexus S with it's s-amoled screen. does this screen have a lower refresh rate then it did?
i know normal monitors have about a 60hz refresh rate but i know nothing about smart phone screens.

You've got me on the specs. I know desktop LCDs/LEDs are capable of higher refresh rates, but those aren't necessary for regular applications (read: non-bluray, non/gaming). Not sure where a smartphone like the D3 would land in the gamut between 29mhz and 120mhz.

I've got a little...not exactly ghosting, but similar...on mine. It seems to me that the display controller for the pentile screen isn't outputting all of the color channels at the same time, so i end up with a red fringe or bloom around objects scrolling across the screen. Hopefully, a firmware update for the chip can fine-tune things.

hmh i wish.
29mhz would be 29,000,000 refreshes per second XD
on computer monitors 60hz has been the norm for a long time. all my old CRTs use it. the newer 3d tvs and such generally need a 120hz refresh rate at the least.
even my dell inspiron 1420 has an lcd with a 60hz refresh rate and it can play bluray.
i remember there being one phone not too long ago that was limited to 30hz and most didn't like that one bit.

you may be right. i'll check another phone or two and if they have the same problems i'll just hope that an update or rom can fix it.
FYI: this has not that much to do with refresh rate, but more with response time. Response times are displayed in milliseconds most of the time.
For example, my uber-gaming-tft-display has a 2 milliseconds response time, which is very low and has almost no ghosting.
So, the question is: what is the response time of the qHD display in the droid 3.
I noticed the ghosting is way more visible on black backgrounds than on white. Good thing motorola changed the background in the android menu's from the default black to white.
I have noticed the ghosting too but have to admit that I actually like it. Especially while playing Emulators like FPSE and Gameboid it brings back the real PSP feeling. I know, its a weird oppinion.

It's definitely got a slower rise-time than fall-time. You can see it on monochromatic icons when scrolling the app drawer in a launcher that uses a black background -- the leading edge is a blurry mess, while the trailing edge is fairly crisp. I'm guessing that the display controller simply isn't using any kind of overdriving to improve response time.
Also, to clarify my previous characterization of the blurring, it appears not so much that the red channel specifically is updating faster, as it is that the white channel is updating slower than all of the RGB channels.
Refresh rate has nothing to do with ghosting. Nearly every TV is actually 60, but they are falsely advertised at 600(plasmas) or use frame interpolation to achieve refresh rates above 60hz(LCD.) The only exceptions are 3D TVs. They actually refresh at 120 hz in 3D mode. Each eye sees 60hz. If they stayed at 60hz, each eye would see 30hz, and there would be noticeable flickering.
What effects ghosting is response time-the amount of time it takes a pixel to respond to a change in state. In layman's terms, how quickly it can go from one color to the next.
Plasmas and CRTs have near instant response times-it takes just nanoseconds for a pixel to change(actually, green phosphors take about 1 millisecond to change, blue and red phosphors change in nanoseconds). Nonetheless, plasmas and CRTs simply don't ghost(which is one reason why I prefer Plasma TVs). Part of this is because the pixels produce their own light. There is no backlight like an LCD.
But on LCDs, it takes the pixels many milliseconds to change. Though they are advertised between 2-6ms, the true response time of an LCD is usually at least 20 milliseconds. The Retina Display and qHD displays ghost because they have response times of 25-30ms. I can't recall why right now, but when you pack in a ton of pixels on a small screen, the response time is extremely high.
The refresh rate on phone screens is 60hz, which is actually why most are capped at 60fps, or you would probably see screen tearing.

very informative, thank you! i knew what response times are but for some reason didn't draw the line between that knowledge and ghosting.
that would also explain why it's so noticeable to me after using the Nexus S for 9 months. hopefully (though unlikely) a new phone will come out here soon with a keyboard and high res screen with good response time.
Hello guys I wrote a guide that will help you improve your battery life because screen is the most thing that uses battery, here is a solution for all that, don't forget that the screen sensor for auto brightness is also taking lot of power.

The first app is useful for Galaxy Nexus only.
The second application is useful for both.
"The downside is that an IPS-LCD may consume more power than a TFT-LCD."

The N7 has a backlit IPS screen, how would adding a filter to make the screen darker save any power? An an amoled screen sure, although I never noticed much power savings with my Epic 4G.

The filter dims the screen because the Amoled is too bright even with lowest brightness, and the filter darken that's right but that also means lower brightness from lamps, the filter is different then lowering the brightness on system.

Doesn't matter, the leds are still outputting the same amount of energy, you're just making the screen darker. Easier on your eyes maybe, not the battery.

No no no just no. Again this NOT a amoled screen. Blacks do not shut the pixels off. Its backlit LCD. The the light is always on when the screen is on. Hell it takes more enegery for a LCD to produce blacks over whites.

Read again, I said the second app is useful which is auto brightness.
https://play.google.com/store/apps/details?id=com.nnevod.loggraph&feature=search_result
This app lets you setup autobrightness based on light sensor values. Gives you the option of using a filter or actual backlight levels. Can let you use level lower than android normally allows.
Why would you need to save battery? The battery life is amazing

Does it really work and save more battery juice?

Replacing auto brightness with a manual alternative that's properly managed will save some battery. Check out display brightness by BigRubberPepper.
It will allow an invisible or barely visible and customizable widget to put a slider st the very edge of the screen wherever you so choose to control the brightness in 1% increments.

But running that widget all the time in the background might consume same, if not more battery life and negate any additional advantage?

Elixir Widgets
I'm using Elixir 2 Widgets for system status reporting and options like when to run GPS/BT/autorotate, in fact I have 32 small panel items up in one widget on one of my screens. On my primary page I also have a 1x1 widget for brightness set to 8%, 23%, 65% for the primary environments i am in.
I've never seen the widget using as much as 1% of my battery life (Ran battery dry over 2d and just short of 7h screen time, almost the entire 2d had it hooked up running Google play to my computer speakers)
I'd say that using a homepage, 1touch widget has had a big part in this. Even compared to https://play.google.com/store/apps/details?id=com.nnevod.loggraph&feature=search_result which really took a while to register the change in light (as much as 45 seconds in some cases) and would reduce screen brightness in bright enviornments when my head was between light source and Nexus.
The screen filter app, while small in size (57kb) and minimal memory footprint (8.5MB), does affect the screen smoothness. Transitions between screens, menus and other settings seemed affected.
Will try it out for a couple of days and post any additional impressions.

none of these actually lower your brightness MORE than the minimum. And screen filters are just a black overlay that goes transparent to fake dimming.

Folks,
Got a question for you -- as per the title. To give you a little background, I bought an S2 8.0, loved it, and then decided that I really ought to replace my existing "data plan" tablet from the S 8.4 to the S2 9.7. So, good-bye to the S2 8.0, and I've got a new S2 9.7 LTE.
All is well, EXCEPT for some screen oddness. I'll have to post some pictures, but I think I can describe it well enough. To begin with, I don't really like "busy" wallpaper -- I just use a solid-color, medium-to-dark blue wallpaper as my background. What I really notice, both in portrait and landscape orientation, is a darker band at the top of the screen -- again, it happens in both portrait and landscape orientation. It seems to be a "viewing angle" thing, as the dark "top" in landscape orientation doesn't turn into a dark "side" in portrait orientation. Instead, when I move to portrait orientation, then the top of the screen has this dark band, and the sides are just fine.
But I don't notice quite the same thing happening when I get into some apps -- for instance, the yellow/orange top band in the "Memo" application doesn't turn noticeably darker. But the green top band in the "Evernote" application shows it IN SPADES, though it's a really thin band at the very edge of the screen. And, again, it's always at the top, no matter which orientation I'm in, that I see the dark band.
Anyway, that's the most obvious stuff. However, when you back up and take the whole screen in view, what I'm really seeing is A LOT OF COLOR CHANGE as I angle the tablet towards me (more vertical) and away from me (more horizontal). Again, just go into the Memo application, and lay your tablet flat on a table, then grab it and tilt it up towards you -- do you get a big change in color, or does it stay the same? I guess I would say that the "white" color "turns bluish" as I raise the tablet towards me (making it more vertical), and it goes more to a normal white when I lay it flat.
I can understand changes in screen quality due to viewing angles, but that's not something that I associate with OLED screens. I sure didn't see anything like this at all with the S2 8.0 that I had. And I've started looking at S2 9.7 tablets in stores, and I really haven't seen anything like it in the stores. Thus, I'm definitely thinking about returning the thing -- unless it's really a case of "they all do it."
So, if you guys could check out your tablets and let me know if you see anything like this, I would appreciate it. It's not worth taking the thing back and asking for an exchange if what I'm seeing is common, but I'm definitely a bit disappointed in the screen quality that I've got with this tablet.
Thanks in advance for checking this out for me, and for any thoughts you'd like to send my way!

I have yet to see an S2 that can display a uniform white screen. I can always see a light pink/purple tint on a white background. If all you're doing is consuming media you will never notice, but if you're reading anything with a white background it gets too distracting. I don't see any issues with uniform brightness though, it looks perfect from that standpoint.

Understood -- thanks. I installed a couple of screen testing apps, and they show no issues. For instance, I pulled up a full-screen blue that was very similar to the blue I'm using for my background, and it was nicely solid blue. Then I pulled up a full-screen green that was similar to the top of Evernote, and it was nicely solid blue. Then I pulled up a full-screen white, and you could see what you and I have both mentioned -- it does change colors a bit as you move the screen around.
So, it's just very strange what my S2 is doing -- it's like it must have something to do with other on-screen elements. I'll definitely take it back and exchange it for another one, but I'm just trying to get a grip on whether this is happening on any other S2 tablets. And it definitely appears that it isn't.
Thanks for your reply!

I've been checking my T815 a little while ago after noticing similar behaviour. The way I see it, the tab S2 screen is very sensitive to the viewing angle. Not so much in blue and red, but very much so in green. In fact, to get a proper green, I have to look dead on. I even notice a change in the green colour: dead on it's yellowish green, while even at a slight angle it is an uglier green. The first is clearly what the device is calibrated for, because that's when things like skin tones look perfect.
I used the *#0*# menu to test.
I compared this to my other devices. On the note4 I didn't notice this. But that may be because of the smaller screen. On my previous tab, tab77, the effect was also completely absent. But that one has a completely different oled layout.
I've already eliminated display modes and auto brightness as influences. I still have to look into the effects of ambient light, since the displays of my devices do reflect differently when turned off. In fact, under some angles the tab S2 reflects a bright white lamp as pure green. While the tab77 always reflects the same lamp as white.
I know that the tab S2 has an rgb matrix that has two Gs for every R and B. That's probably related to the effect I'm seeing.
I've recently bought the 9.7" version of the Tab S2. I was aware of how unrealistic and oversaturated the AMOLED display is on default setting, but luckily this can be turned off, so it was the very first thing i did (though now the white balance is off, but at least it is not oversaturated).
Unfortunately i wasn't aware the fact that the display at below ~75% brigthtness flickers. The lower the brightness the more disturbing it is. And it drives me crazy. I hate the flickering cheap cr*p LED light bulbs, i hate that most notebook screens with LED backlight are non PWM free, and are flickering And after having this tablet for three days, i am hating it too. I frankly believe these products should be banned, because it hurts your eye, and your brain. I thought when we said good bye to CRT monitors, flickering screens will never be an issue again. Unfortunately they are :/
After googling the internet i found this article gs5.wonderhowto.com/how-to/eliminate-screen-flicker-lower-minimum-brightness-android-0157760 but the solution unfortunately requires a rooted device, wich would trip the knox and void the warranty, so it's a no no for me. Then I found several other apps on the play store which are doing the same without requiring root access: drawing a black overlay over the screen and you can set the transparency of it, so you can get a lower brightness without the flickering, because your screen brightness is around maximum, the lowered transparcy of the black overlay makes it less bright. Unfortunately none of these apps work like the one for the rooted devices, wich has a second slider at status bar, so instead of the brightness you can change the transparency at the notification screen. The non rooted apps i found do not work this way, they don't have the extra slider, you need to tap them, so you can get to where you can change the trasnparency and that's very uncomfortable. I tried so far Darker and three other Screen Filter apps, but none of them works with a second slider :/ Also using the Screen Filter apps when there is a smooth color transition on the dipslay (default background picture for example) gives ugly end result. Using a Screen filter app might reduce battery life so i might need to charge it more often (i don't care), but since the display is not flickering, it is always on, it might will burn in faster (i do care, i intend to use this tablet for 3+ years) So i am currently in debate wether i should return this product and get my money back or not. It is a really great device, but this terrible flickering of the AMOLED screen makes me super unhappy, wish it had an IPS display :/
If this is an issue for you too, and you found a Screen Filter app with a second slider at the notification area (without requiring root permissions) please let me know.
Is this just an s2 thing, nothing of the sort on my tab s?

It's not an S2 issue, I've seen several other phones and tablets in low light conditions set to a low brightness flickering like mine.. But you can test it, set a low brightness and start waving your finger in front of the screen like crazy. If you see ~10 seperate fingers -like in the picture attached- instead of one blurry (what you should see if there was a constant backlight), than yours is flickering too.

I see what you mean, but it doesn't bother me as there is no perceivable flickering at all and it only happens when the brightness is below a certain level.
If that certain level would be around 20% brightness i wouldn't care. I haven't tested out yet, but that certain level is somewhere below 70% So -for me- it would flicker all the time.
Eh, there is no screen flickering but your finger is flickering over a light source aka *screen*. It's an optical illusion you are referring to.
I am also very sensitive to pwm on displays, it takes me less than a minute to feel sick from the display having pwm.
Any further solutions to this? Thank you.
I'm using the the app 'Night Screen' it does the job on Android 7.0 on my LG G6 which uses pwm under 35% of brightness even though this is an ips screen. Hope it helps.

So here is the app( https://play.google.com/store/apps/details?id=org.js.oledsaver ) to avoid pwm & use the phone with low brightness.
App name is OLED SAVER
It's simple. You install it & follow the instructions & use it. Enjoy! ?

Thanks for answering this 3 years old post I used Darker in the last three years to eliminate the flckering and was happy with it. I checked OLED Saver now, but it's permissions says to me it's a big no no.
Unfortunately, since Android 8 apps cannot draw a an overlay over system areas (notification bar etc., thanks google! ), so i guess i'll never have an OLED screen phone/tablet again.
Hello all, my past 3 AMOLED phones have been facing burn-in where the keyboard is displayed as I tend to chat a lot! Can anyone give me an option to avoid it? Please don't troll and say use less keyboard!
Might help if you keep the brightness on the lower side, other than that seems like catch22
Also choose a darker theme for the keyboard.

That's why it kept happening for me... The I turn it to light mode and then the burn in goes away!
Dark mode will help reduce it, but I leave my phone set to auto switch light and dark mode based on sunrise and sunset, this way whatever app I'm using also switches, so the light and dark apps, flip button colours as well so anything white on a black screen also becomes black on a white screen so it helps reverse any burnin in that sense too.
For example, texting apps usually also have white icons at the top which can burn in with dark mode, so if you switch to light mode, the same icons are now black on a white screen, so the screen burns but the icons don't, so it all slowly burns in together and nothing becomes noticeable.
Been doing this after getting burnin on my S10+ using only darkmode and light icons left burnin. And then on my S20 Ultra I did the flipping light and dark mode and never had issues but I also had the full screen settings to hide the pinhole camera so it made the entire top black, and then One UI 3.0 came out and they removed that option so now you can't hide the pinhole camera and I had a burnin bar across the top from where it was black lol.
Now on my S21 Ultra I have the light and dark mode set to flip at sun rise and sun set, and I can't hide the pin hole so maybe third phone is the charm here and I won't have any burnin at all this time haha.
Hope this helps.
There is no burn in with AMOLEDs; they have a finite lifespan and get dimmer as they age before finally failing after many 10's of thousands hours.
Don't over drive them by using them at maximum or near maximum levels.
High energy blue pixels are the most susceptible to damage, red the least because of its longer wavelength.
Use manual brightness control. Avoid going much over 50%.
Using full brightness reduces pixel lifespan as probably does high temperatures ie direct sunlight.
Limit usage at full brightness by the second*.
Using manual control ensures you're aware of it and keeps the phone from auto jacking it up on you when not really needed.
Turn it down in low light; don't burn out your retina's as they aren't replaceable.
Use dark mode whenever possible. Use dark or black wallpaper. You Good Lock to get rid of the stutus bar icons; simply use the pull down notification screen.
My 10+ gets heavy usage every day with a lot of keyboard time. At 15+ months there is no discernible weakness or dead pixels of any color at any brightness level.
*this is especially important with static images

Dark mode will help reduce it, but I leave my phone set to auto switch light and dark mode based on sunrise and sunset, this way whatever app I'm using also switches, so the light and dark apps, flip button colours as well so anything white on a black screen also becomes black on a white screen so it helps reverse any burnin in that sense too.

you say you had burn in from keeping a black bar in the area where the pinhole was?
that doesnt make any sense. If it was black those pixels were off and there wouldnt be any burn in
ಠ_ಠ
Get Gboard, And change it to a dark skin, I've never had any problems

Reverse burn in, the screen area being used has a yellowish tone to it from being worn in over time, no matter how long the display is on, it's always burning in and the colour always adjusts over time from the burn in, it's the image retention burn in that people talk about, but the entire screen is always burning the entire time it's used. So by never using the top area the pixels are fresh and have a cooler tone to them than the rest of the screen as a result of this.

Might help if you keep the brightness on the lower side, other than that seems like catch22

Indeed. And to add, perhaps occasionally change from white to black keyboard to even things out.
This is a good one. Says something about fast charging and not showing this message again. Guess they forgot to check don’t show again.
No offence but:
Pay 1.2K for phone after you see super HDR, huge brightness etc. and then limit everything to minimum? Seriously?
If I see them, I will ask EE(my phone provider) to replace it. I had same issue with OP 7 Pro, screen burn ins, they have replaced phone.

Some countries like the UK have better consumer laws than others.

Hello all, my past 3 AMOLED phones have been facing burn-in where the keyboard is displayed as I tend to chat a lot! Can anyone give me an option to avoid it? Please don't troll and say use less keyboard!

From normal use there will be no burnin. However, if you keep your display on showing the keboard all the time it will burn in. Also pixels start to burn in once they are on

Mate - I had burn ins on my screen from things like clock etc, you cannot get rid of them, and it is a design flown, as long there is nothing in instruction etc.

Samsung shifts the AOD clock to help prevent this. However I use only tap on AOD now.
Perps know the deal, organic LEDs have a finite lifespan. Yeah you can drive your car as fast as it will go but you probably don't because you know it wouldn't last very long.
You wonder why the price tag keeps going up?
Freebies are never free.
Using in direct sunlight or at 80+% is just asking for it. In most cases completely avoidable. One can at least limit the time of use at full brightness and not have a homescreen that looks like a Vegas billboard.

So they should not sell them in countries like Spain etc as there is too much sun

I live in Texas desert, the sun here is intense.
It burns out LED traffic lights all the time; OLEDs are far less tolerant.
Simply use in the shade.
The individual pixels are microscopic. That they work at all is amazing let alone being capable of high lumen output with extremely excellent color/gamma rendering.
The AMOLED matrix has 10's of thousands of active solid state components not just the OLED pixels themselves. All are hest sensitive plus the fact the display is helping to dissipate mobo heat while producing heat of it's own. The most heat sensitive component, the OLED is smack on top of this glass heatsink*.
Direct sunlight in especially high ambient temperatures is a real bad plan. You can fry any display like this.
Know, understand and respect their limitations. You will be rewarded with a long lived gorgeous display.
*glass is a good thermal insulator. Do tempered glass protective screens increase the thermal burden? Most likely. If cool at first the added mass will be protective but once the device (or the sun) heats that mass up things will go down hill from there and the display temperature will rapidly climb.

Common sense should prevail I guess. I live in a place hotter than Spain. If I were to use my device in the middle of the day in bright sun light it’ll cook after 15mins. Hence why I don’t. But then would any other device.
