After unlock Black screen appears
please explain your issue!!
screen is flashing or something else?
When I switch off my phone and switch it back on, the restart works just fine but the part when the keypad appears to unlock the phone, the screen turns blank. So I have to click on the power button once and click it back on for the keypad to be visible. I have tried rebooting the phone and it worked fine the first time. But when I restarted the phone again, the black screen appeared again and the problem still persists. Is there any permanent fix for this issue?
Black screen after restart and you need to push power key to unlock...
This is a bug that came in with 10.3.3 update. You have to live with it until Oneplus brings another update to fix it.
