unresponsive screen during phone calls

[lumei 920]

Recently my screen has become unresponsive during phone calls. It would go black and would not respond to double taps or push of the power button. Has anyone encounter this issue before?

Try clearing cache of the dialer app and see if that helps. If not, then it could be the proximity sensor causing the problems.
