After turning off the screen, then turning it back on, the screen on my max pro m2 goes grayscale. This doesn't happen everytime though, just randomly. Sometimes its after 5 times normal colored screen, sometimes more or less. To make the screen colored again I would have to lock the device, then unlock it. It is a bit annoying... I have checked the bedtime settings, nothing wrong. Factory resetting, no use. Even installing a custom rom and custom kernel doesn't help. What am i missing here? Is it actually the LCD component that's going bad? But it's still displaying colors very well though....

Hi,
i have a problem with my three days old HD. Besides the fact it seems to be much slower than it should be, the problem is the screen goes dim after a while. I'm not talking about it going black after a while, like it's supposed to, but in normal working mode it just kinda becomes darker, kinda like notebook screen goes a little dim when you unplug it from power. When i turn it on, it looks ok, but after a while, mostly after it first time goes black due to inactivity, the screen looks dimmed, no matter what i do, and after a few minutes it returns to normal, without any apparent reason, kinda random. At first i thought it might be something in HDTweak, so i did the factory reset, but it's happening again. Any ideas?
Try disabling the light sensor. It is supposed to adjust the screen brightness automatically, depending on the external light conditions. You can disable it in 'Energy', under Start -> Settings.
Well, it sort of works. When i disable the light sensor, i get the screen for adjusting the light on battery and AC. When i adjust the slider for battery, the screen lights up and it's ok. But, the moment the device locks itself (via HDTweak setting, the only thing i adjusted in HDTweak, it dims, and when i unlock it, it's still dimmed. Then when i again go into light sensor setting and press on the slider, it lights up. I don't understand what's going on. Faulty device maybe?
Also try changing the settings in the advanced tab.
Adding a minute or reducing a minute here seems to kickstart the device - and the annoying screen dimming goes away.

I installed a battery booster app from the market, and it had an option to dim the screen, it was on 11%, well i tried to adjust it, and i guess i went way to far and it turned my screen black, i cant see nothing.
im on the Darkstone build.
is there a way to either delete that app or what, i know the phone works as i feel the vibration from me sliding it to unlock from home screen.

The LCD still light up but very dim, so try going into a dark room and wake up the phone. Then you will be able to see the contain on your phone.

Like i said it is BLANK. seriously blank. its not dim or nothing.
Is there a way to restore the brightness on here, because i cant see anything im doin on it.
what you can try to do is, grab a friends phone and try to immitate the same touches on both devices, the best way to do it is by unlocking it, pressing the menu key, click on the corner to make sure u go to the settings, scroll all the way up and find your way to "display" tipically the 4th (or 5th in my case because i have cyanogen mod) and brightness (should be the one at the top) and just try to drag ur finger from left to right to increse it (as it should over pass any 3rd party app) and see if it works, but..... keep in mind these things dependeding on what phone you use to guide you....
screen size
DPI scale
sense??? or not! as settings are different
and other things, also..... when you unlock it make sure its on the home screen
i also believe if you go outside you can see the screen a little bit under the sun, but not completely sure
hope this helps, oh and by the way, if you have a build based on sense go to a sprint store and use an EVO lol, or if u have stock froyo grab a nexus one from a friend and use that (but like i said before, keep in mund the screen size)
yea thats what i was tryin to do. no luck.
I had this problem twice and rejoice, I have a solution!
Simply download "DroidExplorer" for windows.
Boot your phone in android.
Once booted (when your screen turns black), plug in USB, and launch DroidExplorer.
In DroidExplorer, look for the "Screencast" icon (little android icon).
Run that, you will see your screen. Reset brightness to a normal level.
You are saved

When this happens, try shining a bright light on the screen, make sure the device is woken up (i.e. press a hard button) and view your screen from different angles. Even if the backlight is completely off, the LCD display is still active and the graphics elements just about visible.
With this method, you should be able to make enough of your screen to navigate to the brightness settings.
Screencast in Droid Explorer (for your PC) is also a good last measure.
Most apps that control brightness has this problem on HD2, so be careful about going too low in all of them. In Tasker, for example, 30 is the lowest setting that works.
Even the standard screen dimming that occurs a few seconds before screen timeout is not calibrated correctly. In all Android builds/kernels I have tried, the backlight is turned off when it should be just dimmed. Cyanogen(mod) has a setting for the dim level, but the maximum you can use is 26, which still turns off the backlight.
Curiously, sometimes (very seldom) after waking my phone up from standby, the backlight is in a much dimmer state than usual. When sliding the standard brightness from min to max, the actual brightness range varies from barely visible (but still on) to the regular dimmest level. So the device *can* support incredibly dim levels, but I've have found no way of getting into this state predictably. It has happened only 3-4 times over the past 2 months. A reboot fixes it, but I've also gotten out of this state after a locking/unlocking cycle.
So there seems to be several layers to the backlight brightness:
- the actual hardware (which supports much lower brightnesses than we're usually allowed access to)
- the Android API (which probably is the layer turning backlight off below 30, and which occasionally is fooled into using a much dimmer range than usual)
- whatever app providing the GUI (usually showing a range of 0-100% or 0-255).
Does anyone know if there's a reason for the threshold? Is it somehow risky for the LCD display hardware to be very dim?
Great phone but, it appears to be a bug with the screen dimming.
Regarding settings, I have everything turned off. Adapt display is off. Auto-brightness is off. Auto-adjust screen tone is off also.
I know Samsung displays dim if the phone overheats but my phone will auto-dim even if the phone is cool.
What I've found out is that the phone will only dim "permanently" when the screen is about to shut off.
For example: Set the screen shut off to 30 seconds and around the 28 second mark, the screen will dim for a couple of seconds before it shuts off. This is where the auto-dimming will "permanently" kick in. When the screen dims at the 28 second mark for a second, i'll touch the screen so it doesn't shut off. But by this time, the screen has dimmed already and won't go back to the regular brightness. I have to lock and unlock the phone for the dimmed screen to go away.
This scenario has happened every single time. Extremely annoying.
Anyone else experience this?

Yes, same here. It happens alot. Not every single time, but alot of the times.
Try this...
Hi
As the other user said it might be the software bug.
Please try this app. Disable your auto brightness and install this software https://play.google.com/store/apps/details?id=com.vitocassisi.luxlite
This lite version is free. Try this. If everything works, you may consider the paid version to support the dev guy...
What's up guys! I've been having a problem with my phone that turns all red colors a little brighter, to a pinkish color. It's REALLY weird because I know it's not the hardware. When I restart, the colors all go normal and red for about 15 seconds after boot. After about 15 seconds, the color resets back to pink. This change from red to pink happens everywhere. On the home screen, inside apps, and in videos.
I have check all the settings like brightness and adapt display and nothing is out of place.
I will probably factory reset my phone if I can't find a solution but then I'll root to use titanium back up.
Anyone have any ideas?

Are you saying your screen mode is set to adapt display? I have my device set to movie and I can see the change in colors when my S4 switches from the normal screen profile to the movie profile shortly after boot. Although, if you have screen mode set to adapt display you shouldn't notice any change in the colors.

Adapt display was checked. But I found the problem, it was actually the Color Adjustment setting in the "Accessibility" section.
Thanks for the reply!

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.
