the only time my phone has ever locked itself while i was using it as a handset and not a speakerphone or during a BT call, was when the other party hung up on me.
i'd test your proximatey sensor to see what it's doing during a call. it should go dark and then light up once the sensor is no longer blocked.
basically, what you're experiencing is not a normal issue, and steps need to be taken to troubleshoot what is happening.
