After phone call the screen still black

First Poster


When I start a call and move the phone near to my ear the screen goes off. When I finish the call the screen is still off and I can not close the call. I need to turn on the screen with the power button and after that the screen goes on.

How can I fix that? When I move the phone away from my ear I want the screen to go on.

Hi @Desideskata 


Sounds like the proximity sensor.


Just as a quick process of elimination can you please put your phone in Safe Mode which disables any downloaded apps and leaves the stock ones Live and then see what happens just to see if it is an causing this.


"Hardware test: go over to your dial pad and type in *#0*#, this will bring up a number of tests.


Check the sensor.


If necessary you may need to let a Samsung Experience Store or Samsung Service Centre have hands on.
