Hi guys,

Recently had my iphone 4 swapped at the apple store because it had a loose home button and then the one I was given as a replacement I went home to find out the proximity sensor had a major problem.

Most people are getting a problem by the proximity sensor actually switching the screen off but then having trouble of it coming back on, my problem is the complete opposite it just doesn't turn off AT ALL. I've put it right next to my ear and covered it with my finger and the screen just stays on. I'd appreciate anyones opinion on the issue
