Screen lock when making a call so can't end call
When I make a call the screen instantly locks, it's calls fine but it is a blank screen so can't end call or do anything. Unlock button doesn't do anything so phone stays connected until other person disconnects. As soon as it disconnects phone works perfectly again. Only started happening for the last week. No damage or anything been done to it. How can I fix it?
Is dit een goede vraag?
