Hi my IPhone 6s has a problem where if I make a call the screen goes black, if I press the home button the screen come back on shortly but it won’t let me end the call with the red end call on screen. I have to reset by holding down the power button and home. Everything else seems to work ok.
Sounds like you have a proximity sensor problem! How long have you had this phone? Did you buy it new or used? Has the screen been changed on it? I believe the sensor to detect if it is up to your ear is out of position and always detecting something in front of it. Solutions could be to align the sensor correctly, or if the assembly is bad, to replace it. Good luck!
Hi the problem was the screen, any know why the screen would do this?
I had this problem, and it was because of a slightly misaligned screen protector
Probably water touched the screen. Having same problem. I left the phone in the bathroom and some water splashed on the screen.
