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.

I have HTC HERO smartphone, i have tried many different roms and format my sd card multiple times but every rom has 2 big issues i cant live with.
1) sometimes the screen will randomly flicker while im interacting with the phone, i have tried putting it at lowest and highest brightness and even something with overclock widget but its not doing the trick
2) sometimes i press the screen unlock button, and it does nothing, then i press it twice more and it will show the lock screen.
Is there something i am doing super wrong or is this stuff the roms normally do?
i have tried these roms: villianrom, froydvillian, cyanogen 6.1 RC, RCmix, elelinux 2.2 and fusionrom.
I've had a problem on my xperia play, but I don't think its specific from it, because I m on stock...
1 out 10 times I trie to turn it on, it stops on the boot animation.... don't freezes, just don't go any further, the animation keep going... I've noticed that if I touched the screen sometimes it vibrates, only the bottom part, because I was in the unlock screen, I just can't see it, then you unlock and touch on the screen and launch a random app, and then the screen goes as normal....

On my Galaxy S I've similar isue.
When the phone is completely booted I've seen the bootanimation yet until the power button is pressed
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
I'm running aokp jb on my phone. The other day I decided to change my boot animation so I used the tool in Settings to do so, then rebooted. However, after it got past the Samsung logo it was stuck on a black screen for about half a minute before the screen got brighter and the touch keys lit up, and it never boots into the OS. What's also strange is how I can feel the vibration of the pattern lock. I entered the pattern and heard the unlock sound. Is there any way that I could remove the boot animation and bring it back to the stock Aokp one, or do i need to reflash? Thanks.
Try wiping cache... !
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?
