Hi,
I have bought new Mi2 just week back. Then yesterday night power (electricity) went off. So I used Mi2 and started torch.
After few mins, torch was off but my screen display brigtness got set to 0 or something, so I can not see anything on screen.
If I click on volume + then I can hear my stored recordings as well as I can trun on tourch LED... I can feel vibratons, when I
click bottom menu buttons at bottom of screen.. but brightness of screen remains off...
Please, can you help me with what might be wrtong and how to workaround ?
Many Thanks for your big help in adavance...
Thanks,

hi!
I recently bought a xperia and noticed that the screen is flickering when you turn off the automatic adjustment and turn the screen to maximum. Is this normal or should i return it? its very innoying. It's the light in the bottom of the screen that flickers.
I would return it. Mine does not do this, so I wouldnt consider this "normal"
seems that you have a defective retroillumination led... return it
yeah, definately not normal - mine doesn't have this issue
I also recently received my X1. I also note that the light of my screen flickers but only with certain software. It vibrates on the left when loading windows, and on the black bar in touchflo3d between the start menu and the clock ... I can't see if it is a hardware problem and therefore if I should get the guarantee
I recently aquired this phone, brand new too! Bought unbranded of course, and fully unlocked etc etc..
Problem is, when i sit in my couch at night, with my light turned on, bout 50-80cm away, that light is bright enough to fool the sensor to think im outside in full sunlight or something, cuz the "white light" in the home, menu, back, search button lights up for 1 second about, then shuts off, and dont come back on, unless i turn off the light, or hold my fingers above the top part of the screen, then it turns on, and stays on, untill i remove my hand or turn on the light, and then it shuts off after 1-2 seconds again...
Is there a way to either disable this ambient light sensor, or change its sensitivity to light... Cuz this is crazy!
Is it supposed to do that ? I think it's broken.
I have no such problem with my phone.

Go to Menu -> Settings -> Display -> Brightness -> uncheck the automatic brightness! this should fix your problem!
I dont think its actually broken though... I just realised that my HTC Desire is acting the same after the latest update, well, maybe the wildfire is just a tad more sensitive.. But if i fx just have one of the lamps on, then it activates after 1 second... :| Stupid sensitivity!!

Already done! The phone switched brightness settings too damn often for me to be sane! So that setting got torn off about 1 min after the phone was done updateing to latest kernl.
Within the latst few days, the screen on my Galaxy S5 (T-mobile version) has had the following issues:
- Screen not turning on when I click the power button.
- Part of screen flashes when I click power button before going off.
- When screen does come on, it's pulsing quickly and and colors are off -- like all green.
I haven't dropped it or anything. I bought it from Ebay in September (https://www.ebay.com/itm/361348692112).
It seems to do this whether battery is charged or not....
I have solved this. The brightness setting was the lowest and it seemed to have a problem on this setting.
hi . i have v20 h990ds .
when i turned the second screen Off when main screen is On , in setting , the phone didn't show any thing (that is normal) but if i go to completely in dark room i can see that pixels of second screen electrically are On (black backlight can be seen without displaying anything). while i expect that when i set the (second screen being off when main screen is on) the power of second screen getting to off and don't use any battery .
when i press power button to turning off main screen , the second screen goes off at the same time as the main screen , completely.
can anybody tell me that is it occurs for you , please? is it normal when you turn second screen off the power of it (that can be realized in dark room) don't turned off?
That is completely normal. The second screen and main screen share the same backlight even when turned off you will still see some light bleed through the black pixels. They dont have separate backlights so it is still on behind the screen.
Hi! Well as many people don't know but Lg v20's main screen and the second screen are the same panel having a Cut around the left corner which make it feels like that Both displays are separate and also they make some kernel tweaks to make them virtually separate.So even you turn off the secondary display its backlight will still Remain on.
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

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.
