I unplugged my phone from the charger after charging it to almost 100% and unlocked the phone and started playing youtube videos. Everything seemed fine I pressed the power button on my phone to lock the screen. After sometime when I tried to unlock the phone by pressing the power button the phone unlocked but the screen flickered for 2-3 seconds and then started working normally. As it was working properly I tried to lock and unlock again to see if there was a problem. when I locked the phone the screen did not start completely! There is a small visible line on the top of the display and rest of the screen is black! I panicked and tried to lock and unlock the screen again and tried some of the tips on the internet i for sometime it did not start but after sometime the screen turned on again and I was able to unlock again! Everything worked properly the youtube videos were also able to be played at full hd 60fps. After backing up the data I locked the phone again and the problem came back! can someone please help me fix this problem!
