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 all,
I have a Samsung Galaxy S3 GT-I9305T rooted and running Android 4.3 with Touchwizz.
The problem I am having is that the screen will not turn off and pressing the power button will not lock the phone. Holding the power button will bring up the device options menu (power off, restart etc) indicating that the button itself is still functioning.
Restarting the device will boot to the lock screen, however the screen still wont turn off and after unlocking the phone once, you can no longer lock the phone.
In the phones settings, under battery it shows that it doesn't even register the screen as being on or the phone being awake (see image) however the phone is still completely functional aside from the issues stated above.
This problem occurred after accidentally dialling emergency services from the lock screen while watching a video on my computer and absent mindedly spinning my phone in my fingers. As soon as I saw it was dialling I cancelled the call and took the battery out. When I started the phone I noticed the screen wouldn't turn off and the phone wouldn't lock.
Hoping I wont have to do a factory reset, if anyone has any ideas or suggestions, they'd be greatly appreciated.
Thanks
Have same problem with my Alcatel Onetouch Fierce 2. Fairly certain it's from this Kingroot in my case. However I don't know enough to prove this. I started using apps to lock the screen for me but they started not working as well.
Hello,
Yesterday I have unlocked my phone with my finger print (like I always do) and it took about 5-6 seconds for the screen to show something. The backlight turned on rather quickly but the screen remained black. After the screen turned on, it had a bad case of screen retention, the colors were also darker and I could not use the buttons from the bottom of the screen. A reboot solved all this problems.
Also, sometimes when I turn on the screen, it quickly goes dark and the slowly comes back to the initial state. During this time I cannot use the touch screen. It is like it does the wake up of the screen all over again.
I think this is a software issue (I have V20C on H850) and it might be related to the always on display. Also, all of these problems happened when I woke my phone using only the finger print (not pressing the button or knocking on the screen).
Did anything like this happen to you?
Hi all,
i really dont know what happened to my phone. the screen turns black instantly after showing the samsung logo on the start up i tried to reflash a fresh firmware but didnt do the job. the screen is showing the download mode also but after restarting and showing the samsung logo the screen turns to black. sometimes it flickers and shows some of the screen but turns off instantly
is there any fix to this ? does my phone encountered a water damage ? i tried the water damage test on the sim tray but the sticker seems to be on its original state no water damage at all any assistance would help i hope the lcd is not broken my country is on a lockdown and service centers open at this moment. i really need the phone for my work
Thanks
you have to turn on AOD to fix this I guess because I had a similar issue with my screen so a temporary fix is to turn on AOD then press power button screen will work fine pressing the power button directly when the screen is off flickers it and the screen turns completely black after a weird yellow flash.
Hey guys, help me please troubleshoot this issue without resetting my phone..
My Samsung phone (after small/short water damage) has an issue..
If I turn it on, the screen lights up and I can see Samsung logo and welcome screen.
I can login to my phone using pattern unlock and use it just fine, there is no issues, but once screen turns off (due to screen time out, or if I press power button) it will never turn on again, even fingerprint doesn't turn it on..
AOD will not come up as well
Any thoughts?
