There is problem with proximity sensor - small hole in the left top corner near earpiece.
This sensor is switching off your display when you are on call to save energy and to prevent messing on your display by your face (touch screen).
It's sensitive only when in call and you can activate it by covering it.
Check if its not dirty or covered. Maybe you have some screen protector?
If not you ll have to give your phone in for repair.

You can also check your sensors, just go in to the TEST MODE (type on dialpad *#0*#) and tap SENSOR, you can check accelerometer, proximity sensor, light sensor and magnetic sensor. If the phone is vibrating all the time in this test that mean you have problem with your sensor.

Hope that helped

Thank you and more power!
