when I try to end a call, my xperia u continues with the screen off, I take away it's ear and the phone continues with the black screen. What is the solution?
Clean the proximity sensor area, if you have an extra film or protective case it might be blocking the proximity sensor, thus creating this issue.
If that doesn't work then repair your phone
