Hey guys, I have a weird problem with my SGS2. A few days after I flashed Lite'ning Rom v6.1, my phone's display went haywire. I cannot switch the display on, but the phone is working i.e. backlight notification works, vibration works.
I can boot the phone and hear the bootup sounds and everything, just that the screen is off.
In the rare event that it manages to switch on, the display's off color (colors not as rich, black is slightly off etc)
I've tried reflashing the rom, as well as flashing the stock sgs2 rom/kernel and Sensation Rom, but I still get the same problem.
Can anyone help me out here?
Your screen is probably bust, go exchange it if you have warranty.
Hello,
the following problem appears when i try to unlock the phone after some hours: i can see my home screen, but the screen stays extremely dim. When i try to start an app (e.g. browser) the screen turns black. I can unlock it again, but the screen stays dim. after some unlocking the screen becomes normal (normal brightness) and also the apps are startable.
i am using autobrightness, the stock firmware, 4.1.1 (i9300xxdlih) power saver is not turned on.
thx, i hope you can help me solving this problem

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem
Hi,
My Galaxy S7 froze up this morning, and when I hard rebooted it the screen will either flicker green lines, or slowly fades into green bars. This happens whether it's in the OS, recovery mode, download mode, or anywhere in between.
The fingerprint reader and touchscreen still works, since I can hear the unlock sound from fingerprint or pattern.
A few hours ago the screen started working again for a few minutes, and stayed fine through a reboot from recovery mode into normal OS, but then went back to how it was.
The phone is rooted, and I had been running the phone in greyscale mode for the last week using CF Lumen.
Do I need to fully replace the front display and digitiser to repair this?
I have a Xiaomi Redmi Note 9S which has the following behaviour: it works normally until the moment it goes under the sun, then (apparently only) the backlight of the screen is turned off and never turns on again until I restart the smartphone, where it works normally until the very moment it "detects" a bright light like under the sun, then the screen goes black. When this happens, sometimes you can still see the shape of what was on screen, but most times it only goes totally black.
When the screen is black, the telephone keeps working normally (music keeps being played, receives calls, vibration responses keep working, etc...(confirmed it using scrcpy and all is working normally)), only that the backlight is turned off and it keeps totally black. During the night, i.e. with artificial light, the telephone works normally (I was able to replicate the error using a strong flashlight above the telephone, the screen also went black the very moment I turned it on).
What I tried to resolve: restarted many times, disabled every auto brightness (also one that I think is a Xiaomi MIUI only, sunlight detector, something like this) settings that are in the configuration menu, restarted using vol up + power button. Factory reseted the smartphone. Disabled pocket mode before and after factory reset.
Any idea how to proceed? What is killing me is that it seem to be a software issue, like, why the screen don't turn on back after a while, but every time you restart it, or why the phone works all night long (i.e. there no strong light on it)?
How to capture the telephone log (logcat perhaps?) and be sure of what is the exact event that is disabling screen? Maybe I can manipulate it to prevent from happening, or to make screen goes back to normal after a while, as I work as a software developer.
Flashed Ace2 to OxygenOS A.08 and updated to A.10, problem still persists.
Happens both with auto brightness enabled and disabled.

Was this issue also present on ColorOS?
Disable always on display
Any unlock securities
Fingerprint, pin, code etc..
I haven't encounter any screen flashing
I have same issue, tried turning all off, did help, but i need fingerprint unlock... Autobrightness does not work at all, just dimms the screen a bit when turned on, and goes bit up when turned off, no changes in light or dark room
So i believe i figured it out, it is connected to always-on display features, which includes animation for fingerprint unlock. There is an option to turn off animation for fingerprint when display turned off, but then you have to turn on the screen before using fingerprint...
Also this phone gets pretty warm when only looking youtube or browsing, when on 120Hz refresh rate. I used setedit app to reduce it to 90Hz, much better battery life and no heat...
One last solution for the screen flickering, turn off always-on display, and turn off fingerprint animation only, it is under security/fingerprint/fingerprint animation setting, just choose none, it still litghs up the fingerprint, but has no animation, and most important, no screen flicker...
The same problem, flashing, removing the fingerprint, and using the pattern, the problem is gone
Yeah, it started again be me, so no lighting for fingerprint, and then works fine... Just turning off animation did the trick for short time

Do you have region lock too?

Yes, I had a region lock, after contacting the seller. It was opened with TeamViewer, now 3 weeks. There are no region lock messages.
So the seller could remove it? Mine keeps saying only oneplus can remove it. Did you what he did? I am nit sure if it completely removed or just blocked... The bigger issue is these software issues, especially flickering which could damage the screen... I wonder if these issues exist on all oxygen os phones, or only on these flashed from color os

So turning off lighting for fingerprint fixed the problem for good?
Yes, turning off any always on display features, which includes animation and lighting for fingerprint does eliminate the problem.. i suppose it is some drivers for AOD that are incompatible. Same goes for light sensor, if you test it with software the problem is obvious, light sensor does not work at all, it is recognized, but it does not react to light changes.
Hi All,
Could anyone comment on the minimal requirements to avoid flickering and potential random restarts? At this stage I turned off AOD, turned off fingerprint for locking/unlocking (only use pass + face recognition) and turned off the auto brightness. With these settings the flickering/random restarting problem is gone. I just wonder whether there is a solution with potentially fingerprint for locking/unlocking off, but with auto brightness on and with at least basic AOD on. Thanks in advance for your help!
Hi I have the same issue screen flickering and diming after turning one the screen with in addition and the most problematic the call is blocked by a message concerning the region.
If I make a factory reset the calls work work a time then the same problem comeback
i fixed screen flicker... show fingerprint icon off, Finger print animation off, AOD off. Auto Brig off
