Question Display issues

It is normal for display to go blank due to proximity censor while making calls. In my case however,occasionally the display stays blank even after the call gets over. This also happens every now and then when I lock the phone, only to never unlock. At times, the displays backlit switches while unlocking but not all the time. The phone's processor stays awake in both the cases (calling/locking) and the phone rings & vibrates perfectly on making calls. The only option that I have in such cases is to restart the phone. Is anyone facing similar problems with their phones? I've done a factory reset off late but still the problem persists.

Are you using a screen protector? May be you haven't aligned it properly and hence proximity sensor detects it and turns off the display??

I've had similar situations happen to mine, but I figured out that after a Skype call on my phone, the proximity sensor will remain active and will sleep the screen if something's covering it. I'm not sure if you have skype running, but if you do, that might be why.

I don't think obstruction of the proximity sensor is an issue since this problems occurs even when I lock and then try to unlock the phone. Also the backlit turns on at times when I try to unlock the phone.

Well, what you're facing right now is a classic example of what people face when they keep on the protective covering used on a new phone when the phone is shipped.

If you think it's not the issue then search for any apps which you might have installed? Run the phone is safe mode and see if it acts up? Flash stock images or do a reset to rule out the possibility of a software issue.

After few days of working flawlessly, today again the display blanked out while it was locked in normal mode. I tried unlocking the phone but only the backlit would light up. So I restarted the phone, activated the safe mode as suggested by you and then few minutes later, again the display blanked out. What should be the next step now? Please elaborate on flashing stock image. I've earlier done a factory reset but I immediately installed all the apps.

Well, if you're facing the issue in safe mode as well, any apps might not be causing it. To flash factory images, you will need to unlock the bootloader. Follow the guide which is linked in my signature.

Since you don't know about how to flash stock images, I assume you haven't rooted and undervolted? Display black outs while unlocking the device can be caused due to undervolting as well.
