[GUIDE] Green Screen Issues on MIUI No More!

Hey Guys,
I have figured out how to get rid of the ugly green screen issues with 3rd party kernels for MIUI.
Goto Settings
Display Settings
Turn automatic brightness on
Adjust the slider until the screen is at the lowest (before it turns green)
Go into advanced mode
Turn on Use Custom under Light levels
Light level to dim - set to 10
This should fix all the issues with green screens!

I never had any green screen on miui, with official or neo/vorbeth/glitch kernels.
I was curious and tried what you posted above, and I can't do step 4
3. Turn automatic brightness on
4. Adjust the slider until the screen is at the lowest (before it turns green)
If auto brightness is set to "on", I can't slide..

That's odd, maybe the new versions fixed this problem. I guess coming over from cm7 if you have custom brightness it will turn to green with miui

it worked, thanks! my dim level was set to 5, changing it to 10 worked perfectly.

strange... never had this issue when i was on miui and that was yesterday.

they say that in my case i need to replace the screen in order to fix this issue... if anybody have other idea...
thanks in advance !

I have instaled on my defy green lens, a 2.3.6 full rom, and i have been searching and i cannot find any one with this problem, a few seconds after restart the phone the screen brigth dims to a point, it is only possible to see in a dark place. The brigth settings doesn´t react, only the buttons change there brigth levels. The problem isn't the screen because when the phone start the motorola symbol appear brigth.

If you can go to market install root dim app put all setting to 255 (full) then save then reboot.

sorry, but do you have the automatic brightness on?
i just moved to the GGL-ROM 2.3.6 also, and my first impression was exactly the same ... the screen brightness was very low.
i just turned off the automatic brightness setting and set it manually.

[Q] [HELP] SGS4 brightness messed up! Too bright or too dim

Today after ending a call, I was about to leave my house when I my phone wasn't responding. The screen was dark but the keys were lighting up, so I didn't pay much attention and pulled the battery out. After rebooting, I learned that my brightness calibration is wayyy off!! It is very dim or super bright (that my screen is a bright reddish orange yellow). I tried a few screen brightness calibrator apps and learned that from 0 to 199 the value of brightness (lux) remains the same - super dim!!. The moment i put the brigthness at 200 and upwards until 255, the phone becomes super bright!!
I did a factory reset and flashed the stock ROM via Odin. Still no change. Any assistance on apps, mods or anything I could try before returning the phone to AT&T?? Thanks in advance!

Seems like you've done anything you could do to be honest with you

[Q] Galaxy S4 I9500 Screen flickering problem

Hi, started this thread to see if anyone had the same problem I'm having with my screen.
I have a Galaxy S4 GT-I9500 (Octa-core variation), it is running 4.4.2, rooted, stock Touchwiz.
The problem is that the screen starts to flicker almost as if it would want to turn off, when in low light conditions and auto-brightness on, it continues to flicker unless I set the brightness between +2 and +5. I can reproduce the issue without auto-brightness setting the brightness to the lowest, one notch above the lowest and there is no flickering. It is noticeable in white backgrounds and also when swiping down the notification center, that's the most noticeable instance but you can see it in the home screen and in any app.
I started noticing it when I had 4.2.2 Jelly bean (rooted), and I updated to Kitkat hoping it would be solved but it is the same, I updated through Kies and rooted, no Factory reset, I want to try that as last resort.
Funny thing I discovered is when I set Juice Defender to control my brightness it does not flicker even in -60% brightness, but when the dimming happens before the screen turns off it does flicker (and the dimming thing is controlled by the OS I think, not Juice Defender).
I wish I could put up a video but I don't have another phone to film it.
Anyone know if this is software or hardware? What can I do?
I'd like to add, that I changed the battery, disabled overlays in developers option, forced GPU rendering, tried Pimp my rom and played with all the settings, checked and unchecked every option in Display settings and it still flickered given the low brightness conditions.

I think I've found the best solution out there for most annoying screen flickering issues... Done a substential amount of digging and finally discovered the app "Twillight" works like a charm by enabling backlight control feature... Try it out first, then thank me and share your experience here ...

A5 2016 sometimes won't wake up, screen flashes

Hi,
I have this phone for little over 2 years. For over 1 week now I'm experiencing my phone not being able to wake up when I use the power button/home button. Whenever I push the button, the screen flashes for like 1s blue color, you can also see that the notification panel is blacked out and part of it green and it doesn't wake up. Sometimes it doesn't even flash. It used to take about 10 tries to wake it up but today I couldn't wake it up. I performed soft reset, I couldn't see the booting animation at all but it rebooted, buttons lit up and I was able to get in. It's like the phone is working fine in the background but the screen doesn't light up. I can turn down/up the volume, take a screenshot, get into settings, open apps, write a message but the screen is black. Even my alarm went off this morning but I couldn't dismiss it.
I downloaded an Always On Display app. Although I don't actually see the screensaver when it's locked, it's still on and it's easy to get in beacuse of it.
It all started with the screen flickering on minimum brightness. In February this year I had the screen replaced for the same issue but this time it's worse because of the blacked out screen.
Any ideas what it could be? Faulty display again?
Thank you

It's over to have this phone for little over 2 years now you should have to change
TIP:
Flash a new stock rom of your phone from sammobile via ODIN.

That would be great, but I'm not a person that buys new phone every 2 years. I was thinking about it though .
When it comes to flashing. Do you think that would help? I don't want to end up with a black screen unable to set the phone up again. Cause overall it's working great .

Hi, i have the same problem, i'm from Belgium, and I have blinking screen problem and wake up screen problem :s
is it a software issue (nougat???)
before the big update (marshmallow i dont have any problem)
i'm on firmware A510FXXS7CRJ6_A510FLUX7CRJ1_A510FXXU7CRJ6_HOME.tar.md5

Turn screen brightness up abit to stop the blinking of screen. It's an issue of the screen hardware itself at low brightness after wear and tear. As for the hanging issue, maybe it has to do with your AOD app? Try uninstalling the AOD app OR flashing a stock Rom OR custom rom OR factory reset and use your phone at a higher brightness that the screen does not blink and see whether it still persists.

Thanks, because of my past experience with the same problem earlier this year I know about that "solution". Unfortunately, it makes the battery die faster as expected. Which is sad because I used it mainly on low brightness. So it's really not a solution at all.
I got rid of the AOD app because I found out that the phone lights up on 2nd try. AOD didn't work at all. I have to wake it up, put it to sleep and wake it up again which is always successful and the screen lights up. The screen flashes white about 3 times in a row now otherwise it works.
I haven't flashed it yet although I wanted to. But I will see what can I do. Thank you though!

I'm having the exact same issue using LineageOS.

It's already been 2 years, but since this thread is one of the first results on Google, I'll gladly add a solution.
Exact same problem for me, went through two screen repairs under warranty, and it would always come back a year later. No difference between Samsung OS and LineageOS, though I haven't tried rooting it.
Found on Ifixit: this issue is related to the AMOLED screen technology used by Samsung (among others). You can look it up, apparently there is a bad (?) voltage management in low brightness which worsen with time.
I could fix it with the "OLED Saver" application on Play Store. It works around this voltage management and allows you to reduce the brightness without the green flickering.
I still got white flashes after the installation, but not anymore the day after. I could even disable this application without the issue coming back.
I don't know what kind of magic cleanup this app performed, but it really is a (screen) life saver.
