The phone stayed in my pocket most of last night, but I picked it up to see when the last bus would go and thought the battery was dead. But it's like the sensors are broken, the screen is on the lowest brightness setting, just like the LEDs are completely broken. It has flashed a few times, and the brightness did come up to a normal level for a few seconds, but today it's completely dark/low light.
This makes it very hard to use the phone, does anyone have any idea what could be wrong? I'm thinking about reflashing it, but I'm not sure that would help?
I think the screen is broken... I tried to hard reset it and it still doesn't light up. It's completely dark, so I can't see anything when I'm outside...
This is really bad...

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.

have android desire build on my hd2 and it works great...if i put my phone in standby for a few seconds it comes back on just fine but if its in standby for a few minutes only the keys light up and i have to pull the battery..i was reading some posts and thought i saw something about deleting the data.img....was wondering if this was the solution to the problem or something else..
If you have a black screen and the button lights are on, you can stick it under a bright light and turn it on. It should come on after that. If that's the case then turn off automatic brightness and see if that corrects the issue.
auto brightness wasnt on when i went to go change it...i flipped to it just to see if it would do it but it does the same thing..if in standby for too long,the buttons light up and the screen lights up black but thats it.

hi,
Today my backlight on my screen just gone off. Did factory reset, battery out/in, hard reset and still nothing. Its like setting brightness to minimum and i almoust can see anything. Need help with this please.
I've notice 351 screen brightness is turn down compared to 318 which was too bright in my opinion. Kinda sucks because I bought adjbrightness app. Now its useless.
Sent from my Dell Streak using XDA App
Yea but on mine its totally gone dark. I cant change anything by any settings. Leds of home,back and menu works fine and flash from camera. Everything works fine only screen is very dark. Its like swiching off the light in the room. You can still see things but in darkness. Its looks like lighting bulb is dead or something. Any ideas or tips?
Sounds like the LED backlight burned out, and did so way too quickly. But, try flashing a different ROM and see if that helps, if you believe it to be software related.
Problem is even when i go to fastboot mode is the same. Its looks like hardware problem. Its any chance to check in fastboot backlight? like benchmark or test?
Nope. No test modes for anything like that.
I have an N9005 that I bought second hand just under a year ago. It's running the Phronesis 4 ROM. About a week ago a one pixel wide bright pink line appeared intermittently down the right-hand side. It looks like this (only bright freaking pink): http://forums.androidcentral.com/at...-bright-line-being-shown-display-p1070045.jpg
Today I was playing Fallout Shelter (always makes my phone pretty warm and eats battery). 15% battery warning comes up so I take it to charge. I notice the screen doesn't turn on. There is a momentary flash of dim colour at the top, but otherwise the screen is completely black. I tried pushing the power button several times, but all it did was a momentary flash of dim colour at the top but still black each time.
I took the battery out for a bit, then put it on to charge. The on screen charging display did not appear (stayed black) but after a bit the LED lit up to indicate charging as it would after the screen display turns off. I left it for a while and eventually the screen started working again (99% charge when I checked). I was then able to boot like normal.
However a while later the screen would not turn on again (just the momentary dim flash of colour at the top before black). I didn't do anything with it in this time. It just sat in standby before I tried using it again. The back button and hamburger menu buttons are not seemingly lighting up either. But the led works fine with notifications. I tested calling my phone and it rings fine - if I slide accept the call where it is normally on the screen, I can accept calls and talk like normal. But the screen remains black. So clearly the digitizer works fine.
I have tried taking out the battery for a long period of time, taking the battery out and discharging the remaining power by holding the power button (5 minutes), I have tried taking the phone apart and cleaning the display connector with some isopropyl alcohol and firmly reattaching. Screen is still black.
Is this a problem with a malfunctioning LCD or could it be something like the GPU? I don't want to pay $150-$250 for a replacement screen assembly only to find that it's some other problem
Thanks in advance!
I would suggest to get a new device.

I prefer to repair rather than replace unless I have absolutely no other choice, thanks.
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

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.
