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.
Hi everyone, as you should know the Asus Zenwatch 3 has an AMOLED display. From my understanding this should mean when displaying the colour black, the pixels should be turned off completely (like on my S7 Edge).
I was looking at my watch in a pitch black room with an ambient watch face displaying a black background and it appeared slightly reddish. Compared with my LG G Watch R sporting the exact same watch face it was clear the LG had the black pixels turned off but not on my Zenwatch 3.
I've attached a couple of pictures taken with my phone of the Zenwatch 3 in a pitch black room, one with normal shutter speed and the other with a 2 second shutter speed. Evidently the 2 second shutter speed shows that the display is in fact not turning off the pixels. The pics were taken when the watch was charging and in ambient mode with a watch face set to true black only.
Can anyone else confirm that this is the case and maybe a reason why? I'm worried that battery life may be affected by this with always on display enabled.
Lastly on a side note, are the black lines that aren't illuminated something to worry about?
Mine is the same, including a similar set of dark lines. I've seen others on Reddit report identical concerns.

Noticed this too, thought I was crazy lol...kinda waste of an AMOLED screen.
Hmmm ok at least I'm not the only one. Hopefully Asus is able to change it in a future update.
Yeah it is weird, black watch faces aren't truly black. I think they did it so watch faces can blend into the color scheme of the watch, if you notice the color overlay on the app launcher
That's because of auto Brightness. Turn it off. This impacts battery life. I observed this on very first day after the purchase. Using manual Brightness since then.

I just tried disabling Auto Brightness but the red tinge of the black background still exists.

It doesn't happen with me. If I turn off auto Brightness the blacks go complete black. Do you have live display turned on your phones? If so try disabling it. May be this setting depends on your phone. All I can confirm is if I turned auto Brightness off amoled works perfectly.

Not sure what you mean by live display but I just have a stock S7 Edge. I prefer keeping the auto brightness on for my watch so I guess I'll have to live with it.

Live display is when some ROMs allow the screen to have a tint at night time so the blue light from the screen won't affect your eyes at night
Me too have similar display and black line like that.
Glad I'm not the only one with this condition.
I also have those black lines, was about to get a replacement but since I'm not the only one and it doesn't affect overall performance or aesthetics its fine.
Yeah I have also black lines and screen is not completely dark with totally black watch faces
Turning off the auto brightness is not a solution. Its a pain if you had to adjust the brightness all the time
Hello everyone, i really love my p20 pro but it seems like I have some kind of a Display bug. Whenever there is grey and black(so that the display is turned off there) and then swype, I have weird "veils", as you can see in my video. Does anybody have the same issue? You can see that as weel when you are in dark mode and the scroll in your settings. Or is this just because it is an OLED display? I had an IPS one before and that definitly did not had issues like that. If you want to reproduce it you can use the image from the video as well.
Does someone know a solution to this besides bringing it to a service center? Thank you!

The problem is the oled screen most of them do that.
This is normal for OLED cause the pixels individually produce light. So they are switched off at that point.
At last found some one has the same complaints with me.
Yes this is amoled nature, the pixel take times to turn from completely off to some colours. Unlike ips LCD displays the backlight is always on.
But, i only notice this problem ob very early generation Samsung phone (like Samsung S2 /S3) generation. I actually try to do the same thing on the display unit of Samsung s9.
Guess what?Samsung panel doesn't have this black smearing effect
I do believe it can be fixed via software. Cuz I only notice this in gallery and menu setting. Playing video doesn't have this problem
Anyway please feedback your complaint to Huawei so that they can hear you and start to do something!
After lots of research, I finally found a solution, but its temporary.
Download & Install ScreenDimmer (Dims Notification Too) By Etsang From Play Store.
Keep the auto brightness off, and device brightness @100% (Or Above 50%), install app, give permissions and change brightness from app according to your usage, thats it.
I think red tint is a software bug, not a hardware, because at last the motive is to decrease the brightness (dim the display) without red tint. App is also doing the same. The only difference is it has no red tint.
This works but if advise against using it. It records your inputs.
More to your point of it being a software bug, I agree. I wats always under the impression that they could fix it by adding blue in software based on the light sensor input. I noticed that if you put your phone in grey scale (in notification tray) that the grey for the icons in the tray that are toggled on, are actually grey while the other have a red tint. Normally the toggled on icons are blue when not in grey scale. The fact that it can show grey properly under these conditions as well as the one you described shows software could address the issue.

Oh wow it works but im gonna wait for asus to fix it.
Yeah, actually the brightness mechanism of oleds and LCDs is different, lcds just have a backlight led that would get brighter or dimmer pretty straightforward, but OLED's case is different, getting brighter or dimmer means showing different frequencies of the same color so our eyes can see that color brighter or dimmer, thats why when you turn the brightness of an oled panel down you still dont feel the way you do with a lcd
Long story short, this tint issue is most probably caused by wrong calibration of different brightness levels but still, i would take my hopes up with asus...they dont have a good history of customer support at least in their mobile phones section
Btw, thanks for the app and thumbs up
happy to hear this is a software issue. I am sure Asus will fix this with an update.
I knew this was a software bug long time ago. Since I noticed even night mode did same problem too. That's who I found out this is software defently.
Hey guys, hope you are doing great.
I have noticed one peculiar thing, when i sit in pitch dark places with brightness at the end, i face this white issue over my display screen shot attached, it's Google chrome app which showing me these results,(there are many more also)for this to be noticed you must sit in a dark room.
I know it's typical led panel issue and i would like to know if i am the only one?
Do you seriously think we are able to see your display in a screenshot?

If you are in a pitch dark room and see no anamoly then your's display is good. If not you will see a whitish tint over the top area
And btw you can check on your device itself, by just opening chrome(if it's black) and in dark room with brightness as low as possible.

Enable feature in display settings under anti flicker mode to on. and check again your screen in low light conditions.
Yup, that worked, it increase overall contrast for low brightness, is this condition(tint) is normal for amoled panel, or i am just unlucky.
