Hi guys,
When I make a phone call, the display/screen turns off in a flash and i am unable to bring it back. I press all the buttons home,back,power key but only the button light glows but there is no response in the screen. Only if the call is ended by the opposite end i am able to get back to the phone.
Note : I had just replaced my touch screen glass yesterday ( Not the LCD ). Does this have something to do with this issue ? Or if there is any other solution please clarify my problem immediately.

My KS20 rom is Unoficial one from arthemus build 29022
did you solve your problem? i have the same issue too.
[Solved the problem by using mymobiler to adjust the screen brightness]
I'm running all stock on my Nexus 5 with 4.4.2. If I talk on the phone with it next to my ear the screen turns on and off as it should, so I know that the proximity sensor works. If I use the speaker phone and have the phone away from me, the screen goes black after a minute (which is what I have the screen timeout set to). The only way I can get it to wake up is to hit the power button. This is not a big deal except if I want the power button to end calls. Is there a way to wake the screen after it times out without using the power button? Or, is there a way to tell the phone not to shut off the screen during calls?
Thanks in advance.
Hi,
I have broken my display recently and now I’m facing a riddiculous problem. How do I switch the phone off, when the screen is not working? The phone is working well, however I am not able to switch it off in order to prevent further damage, as the screen s cracked open. The only thing I managed to do was to restart by holding the power button pressed.
Thanks for any piece advice.
Hi guys, I just got a uleFone U007, and having a black screen problem.
The thing is that, after every few hours when I press the power button to unlock the phone, the screen stays black .
I am able to blindly unlock it by swiping on the screen, and I can feel that the screen in responding in background.
The navigation buttons are also responding (phone vibrates on touch).
However the screen still says black. And if I restart it (keep power button pressed), the screen is coming back, but again, only for few hours.
Do you know of any solutions for that? For me it seems like a software issue rather then a hardware problem. A GUI crash...
Also if any ideas on how to further investigate that will be helpful.
Thanks

Are you on the latest update? is your phone rooted?
Hello everyone,
I bought a LCD replacement for my OPO, and asked a friend to replace the screen (he had his own OPO, and changed the screen on it a couple times, so I trusted him).
The frame was not included, so the phone is without it unfortunately.
But I have this problem with the screen itself...
I boot the phone, everything goes well, it boots, everything ok, I can do everything...
Then the phone goes to sleep after the 30s, and sometimes when I press the button to turn it on, the lights in the bottom light up, I can hear sounds, I can swipe to answer calls for example, but the screen stays all black.
If I press the power button to turn it to sleep mode and then click again to wake it within 1 or 2 seconds, it works everythime.
Its just when it goes to sleep... And then I have to press the power button to reset the phone, and it boots again.
I'm using the LineageOS Rom, and I never had problems like this before replacing the LCD.
What caused this? Could the screen be "broken" when I bought it?
Thank you for reading this and for the help!

Well,clearly the issue is lcd itself.Happened with me on my last screen replacement,it was defective.Though in my case,I had to power on/off the device to get the display back.Get a refund or replacement,there's no other alternative.
