Hi all,
May i ask the solution for this problem: sometime when i try to unlock my phone using the home or power button, the screen keep become black back or autolock it back which means when i unlock the screen will have a display, then in a few second it bcome black back.
The problem can be solve after u leave it a while or when ur phone ring of received msg.
Any idea on the problem and the solution. I have format the phone but it seems like the problem may occur sometimes. So is it a hardware or software defect?
Thank you very much

My screen's backlight would not work after i press the sleep button.It would respond because as I randomly scroll through the screen I can feel the vibration of the touchflo and if i hold the phone up steady in a certain area with enough ligh such as the glare of the sun I can partially see the screen but its very hard. Only after i reset it the screen would come back in and the backlight would work until it goes into sleep mode after being inactive. I have tried installing a new Rom but it still didnt solve the problem. What do I do to repair this? I was assuming it was the flex but then I thought if it was the flex the screen would not work at all ? Can somebody help me

I'm assuming you aren't asking where the backlight controls are. It seems like you're saying that the backlight simply doesn't come back on after putting the device to sleep.
If you are flashing custom ROMs, preform a task29 (search) and then re-flash the device. If this doesn't fix the problem (make sure you test it before installing anything.), flash the latest stock ROM and see if it continues. If so, see about a warranty repair/exchange.
If this is on a stock ROM, re-flash the latest stock ROM and see if this behavior continues. Test it before installing anything. If it doesn't clear up, ask your carrier about a repair or exchange.

Hi, I have the same issues. My phone does not recognize touch when it is cold. When it was in the pocket outside or facing a table. 2-3 times turning on and off the screen brings it back working.
I read an article from Sprint that there are protector foil issues with the capacitive display, but I don't have any.

Hi, I guess I have the same issue. Bought the Note II a week ago, came with 4.1.1 and it automatically updated itself to 4.1.2, so don't know if this problem was present with 4.1.1
When I press the power button to lock the screen and wait about 10 minutes, the screen becomes unresponsive, no tap or swipe works. Have tried swipe, pattern, pin for unlocking, result is always the same.
Strangely, at that unresponsive state, the S-pen works and I can unlock and do other things. At that state, touching with the fingers still doesn't work.
The only way to return the screen back to normal is, press the power button again (sometimes need to press the power button twice).
Have done factory reset, the problem is still there with both Sim card and SD card removed.
Has any one found a solution, is this related with 4.1.2 upgrade or a hardware fault ?
Thx in advance,
Regards
I have sent mine for repair. It is a pity that Samsung does not do an exchange.
It is a hardware fault for sure. I made a video to demonstrate the behaviour.

I bought my device (P600) a few month ago,
and suddenly (without changing rom/karnel or doing root) i got a big problem -
when i push the button that close the screen(turn off the screen but the device is still on) or if the screen is turned off automaticly, the screen stay off forever. Even pushing the power button doesnt turn on the screen.
The only way to turn the screen on again is to reset the device (by pushing the power button long press).
I almost sure that the problem is a hardware problem even that it's look like a software problem because after i saw the problem i changed the rom and the karnel to other option to check if the rom/the karnel is the problem and the problem didnt solved.
Someone have a clue which element make the problem?
Thanks (and sorry for my bad english)

I'd bet money on it being a backlight issue.
Test it again in a well-lit room with a bright lock screen wallpaper, something with a lot of bright color. Once the screen turns off, wake the device and look carefully to see if you can see anything. You might have to tilt the screen, but you should see a very faint, dark image.

Amazing that's was the problem!
There is a way to fix it? What is the component that causes this problem?
thank you so much!

Unfortunately I don't know of any solution other than sending it in for warranty coverage or replacing the screen yourself.
I've seen a couple of other posts on XDA involving the same issue, but never saw a solution. I've even seen this issue a couple of times IRL (not on my device, thankfully) and have not been able to find a solution. The two times I've seen this issue, the backlight level could not be adjusted, either. Whether it was set to automatic or manual brightness, it would never adjust, the backlight was locked at a constant level, until the screen turned off, and then the backlight would NOT come on again until the tablet was restarted. Reflashing stock firmware and doing a factory reset did not help, either. On one of those devices, the backlight DID start working again for a while after a manual wipe of internal storage, but only until the tablet was restarted, and I think that might have been a coincidence, I was not able to replicate that again.
So in short, I'm afraid I don't have a good solution other than hardware repair/replacement via warranty.
this has just happened to mine - will have to send it into repair, but it had CLEAN ROM installed so they might argue re the Knox trigger - really annoyed about this!
Hi all,
I have some trouble with my Z1 compact. Very often when screen is off and pressing powerbutton (to get to unlock screen) the screen goes on but in the same sec goes it off. The same thing can also happen if screen is on and I want to turn it off -> it goes off and again on and I'm back at unlock screen. This issue appears kind of randomly and I have no idea if this is a software bug or a hardware problem.
Using CM11 M12 stable. Any ideas? Thank you

I have the same phone and OS, and have seen the same issue, but until I saw your post I have dismissed it as something I was doing when pressing the power button. I believe it must be a software bug, since I did not have the problem when running the stock OS. Perhaps it is worth a bug report.

I use Xposed and GEM Xperia Xposed module, that has 'wake up with volume keys'
Not really a solution, more of a workaround
Hoi everyone, i have a question and looking for a solution. After cracking my glass and replacing a aftermarket display&digitizer, an issue accured. The screen goes black after a while and i cant start up using the On an Off switch. The phone is still working i can feel fibration using the volume and on and of button. Sometimes i can use the display and of the sudden it truns black. I have to disconnect the battery and start up again.
I tried solving any proximity issues as the phone seems to use the camera when unlocking the screen . You can see a blue ring around the camera when pressing the button but it stops there. Then i went to disable all sensors. No help there. Last i switch of the use of the lock screen. It did help the phone can can be used for a few hours but then goes black again.
any explanations to why this happens and any solutions?
thank you in advance
best regards Vincent
