Reason of Note 4 screen remains dark after calls issue

The proximity sensor of your Galaxy Note 4 is most probably the main reason behind this issue. The sensor is used by the Note 4 during a call in order to check the position of your face. If your face is near the phone, the display does not lit continuously while you are in call. But if the proximity sensor is blocked or covered then it may happen that your phone stays at the “calling” status though you put off the phone.

So the first thing to check is if the proximity sensor of your Note 4 has been covered or blocked with something. The sensor will be found next to the ear piece. So the things you need to check are:

  • Is any dirt or dust there in front of the sensor?
  • And if you are using any screen protector then is it covering the sensor and not letting it to work properly?Galaxy Note 4 Screen Remains Black After Phone Call-2
