priv proximity sensor

After june update my proximity sensor malfunctioning. Screen goes black when on call and never cones back. Tried BlackBerry virtual test it is not going beyond 10 cms range hence, not passing far proximity test. But, when I press the sensor area with my thumb it detects 25.5 cms only for few seconds after tgat it goes back to deteriorate. Any help?

Check if there's any dirt or smudges over the sensor area. Also some people have found gently vacuuming the speaker grill in that area has sometimes helped (although I'm not sure why).

I have done all these things only pressjng the sensor area works but only for few minutes after that it again acting weird
