Check if your proximity sensor is not covered by a screen protector or a clip from your case. (proximity sensor is in the same place as front side camera.
If that does not work do a soft reset. (no data will be lost)
Push both power and Volume down till the phone starts to vibrate. (mat take 10-15 sec)
After it startup check if data and time are still correct.
and see if you still have this problem.
