I found the perfect app! Its called, "Screen Filter" in the Market. It puts a virtual filter over the whole display to make it dimmer without impairing functionality.
This is perfect for our Amoled screens because power use is directly proportional to overall screen brightness not backlight brightness like lcds.
Also, don't set it on minimum or else you won't be able to see anything and have to wildly press the screen in a frantic attempt turn it off like me
HAHA this is exactly what I needed for my late night Pocket Legends sprees.
Perfect! This is exactly what I've been looking for, hate disturbing the GF when I can't fall asleep and need to check XDA
I used Screen Filter for about 3 days, and it seemed like the battery drained faster with it on than with it off. I think it's because it runs as a background application instead of simply modifying the brightness.
Hello everybody, I have the following "visual effect". It happens roughly 50% of the times the display switches off. It doesn't matter if it is by it self, by the power button or by a software button. In the very moment when the display switches off, a greenish dot in the center of the display flicks for a split second, along with a same color vertical line trough the whole screen. Obviously it is not supposed to be this way Beside this issue, there is no other problems with the display or the phone( for now). What do you think about this? Thanks in advance
Sounds like a screen off CRT effect, check you tube to see if that is your problem
Isn't the CRT effect a horizontal white line ending up in a dot?
I genuinely think the OP's screen may be defective...

do a lcd test and check if all pixels are working ok
Unfortunately it is not a CRT effect, although it looks a bit like it. The difference is, that the line and the dot( little spot) appear simultaneously for a fraction of a second. In a daylight it is hard to see it, even more it happens just 50% of the times, but not every other time. Its somewhat random.
The *#0*# test do not show much. No dead pixels. On blue you cant see anything, on green and red I think I see a little bit darker spot in the center of the screen( where the dot/spot appears), but there are such darker sports and elsewhere on the screen.
BTW, I noticed recently, that when the screens dims a bit shortly before switching off, this dimming happens not so smooth. How should I say it... it happens on a several steps, although the whole thing is done in less then a second, it is not so fluid. Is it supposed to be this way?
Thanks for your help guys
have u tried flashing a different rom stock
I am on the latest German stock 4.0.4, tried several others, including 2.3.6. .Currently with Hydra kernel. No difference whatsoever. I think the auto-brightness doesnt work so good. When set on fixed value it dims more fluidly.
if u on stock rom and not rooted then take it to a service center
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.
The lack of a front notification light is super inconvenient.. does anyone know of a way to have an always-on display with notifications etc?
Also, I read somewhere that they're working on pie for us, does anyone know details/timeframe?
Thx
Settings->Display->Advanced->Ambient Display.
Not always on but is pretty good. Can be configured to turn on briefly to show notifications
Always on display on an LCD display would be pretty pointless. The battery would drain pretty fast.
For what it's worth the Chroma Logo is what replaced a notification LED just means you have to leave your phone screen down.
This is my post in the Moto G Stylus forum
Disclaimer: I have no idea who makes this app and I get nothing for promoting it. I just think it is a nice addition to this phone.
Found what I consider a nice app for this phone. In the play store: Always on AMOLED.
I like the MOTO built in screen saver, but it only works plugged in and it doesn't show notifications. I was missing calls and messages. You have to touch the screen to bring up the home screen and see if there are any missed calls, etc.
This app has a lot of customization and works whether charging or not. I have my phone in a dock at my desk, so I can see the time and any new notifications at a glance. If it is not in the dock I can leave it face up and see the time, etc. or place it face down and the display turns off. If in your pocket or in a holster or other case that covers the screen the display turns off saving battery. I've gone almost a whole day without losing any charge because it was face down on my desk while I was out.
Pro's:
Nice customization choices
Home or lock screen don't come on when plugging in or unplugging
Can put date, time, battery level and weather on it if you choose
Notifications show and an optional pulsating blue border for a new notification
You can adjust the brightness of the display, but it doesn't automatically shift given lighting conditions (partly a con)
The display shifts around so as not to cause burn in
Con's:
If not plugged in and screen not covered, it will drain the battery faster
Pushing the power button does not bring up the home screen - you have to double tap the screen
There may be better options, let us know - I'm always looking for better options.
Cheers!
