Hello!
I have a problem.
I ported a custom ROM to my phone, but when I lock the phone and then try to unlock it, only sound plays, but there's no screen.
So i have to restart the phone to get the screen on.
How to fix it?

Most of the times i try to unlock my phone, the screen flickers, then the lock screen shows up for about a second, then the screen turns black, but the phone stays unlocked.When i try to unlock it again it happens again for at least a few times.I tried installing different roms, but it doesn't help.This was happening with the original rom too.
every time i turn offf the screen it boot with the bootloader image and make sound also then turn on on screen lock. how can i get over this problem?
for this rom i guess it perfect and very nice thx
I'm just a noob. I didn't root. Didn't unlock my bootloader! I use 4.5.141 (upgraded via OTA) Now having an weird problem! It was all okay! I was playing vector. But suddenly my launcher crashed & the phone got restarted! It took a lot of time to pass the at&t logo. I use holo locker. It comes alright. But I also use pattern unlock! But I cannot pass the lock screen because the touch is not working there!
That means in holo locker, the touchscreen is working! But after that, Motorola's own default lock doesn't work! It doesn't recognize my touch! Besides, after 20/30 seconds, the screen turns off & it doesn't open again by the on/off button. I've to remove battery & insert it again & boot from the beginning! Don't know what happened!!! :'(
Help please? :'(
I'm just curious, could you try to leave your phone without the baterry cover and see if the touch works? it happened to me once and I had to send it to a repair...
you could also try to change the rom to make sure it isn't hardware related.

Try this méthode :
1/ Reboot phone (remove battery for ex)
2/ Hold volume down during boot
3/ You start Android in secure mode (no more apps and widget are start‚ then you can read ’secure mode’ on bottom of screen)
Now try to use phone to see if something's wrong...
Walt for your answer
My S2 boots up fine (screen very bright and animation color not natural) after finishing boot the soft keys lights up but the screen goes black. When i press the home button the screen just flickers, shows the screen for a split second then goes black.Sometimes after many attempts pressing the power button it wakes but screen at full brightness and color is not natural. When i try to press the screen brightness to adjust it goes black immediately.
What i have tried so far, bought a new LCD screen and replace but problem persists. So its not a LCD problem. It was running stock ICS so i flash stock JB after wiping, no help. Root with Philz kernel but when i go to recovery screen goes black so i try Speedmod kernel with CWM recovery and the screen shows the Recovery menu I try to flash a custom rom (can't remember which one) but it won't boot up stuck at splash screen.I even flash GB and ICS stock still no luck.
The phone works fine calls can still get through, download mode screen and recovery screen ok. I actually have not use this phone for a year but the last time i use use it was working fine.
Google all the different Samsung device if anyone has this problem but no one seem to have the problem that i have so maybe if anyone knows or suggest anything else which i haven't tried.
Thanks for viewing
I have found the root of my problem, the damn brightness control in settings is not working. Brightness is at full, unable to set to auto or manually dim the screen.
Screen will only wake with black background. Have to tear apart the phone and figure whats wrong
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.
