Maybe there is something wrong with the device's proximity sensor, which is located near the front speaker and the front camera and which is supposed to be active only during calls.

To test this, cover the upper front part of the device with your hand. If the screen turns off, the proximity sensor is active and in this case, if restarting (or even resetting) the device failed, take it to a repair shop.
