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?

It sounds like you're having an issue with your proximity sensor. If there is no damage to the screen or the proximity sensor, it is possible the issue is caused by your screen lifting. One way of checking is by applying pressure to the top of your screen while avoiding the 2 small circles where the proximity sensor is located during a phone call after giving your screen a quick cleaning.
