Black screen during calling

Most of our Windows phones will be changed to black when we try to call. It will not get responded for sometimes seems to be our phone is out of service. So that we cannot cancel the call. This is mainly affected to the Lumia phones. Nothing to worry it can be solved easily.

What to do:

Double tapping on the power button will gives your old screen for a while. Make sure to cancel the call quickly at that time.

Solutions:

• This is mainly because of the obstacles happened to the phones proximity sensor. It is located near to the front camera.

• If you are using a screen guard (protector) make sure that it is original and suits your phone and also it is not covering proximity sensor. Clean dust particles in front of the sensor.

• Give a slight pressure over the sensor part.

• If again same problem is occurred then, replace your sensor unit.
