Bought a white iPhone 3GS last June and had no problems like this. However I took it back to the Apple store because it had the infamous hairline cracks on it and it was replaced with a re-jigged one.
Now I've noticed that at the end of calls when I go to press the hang up button the screen goes black and doesn't respond to anything I press. I can't hang up or do anything!
It only freezes for about 5-10 seconds and then pressing the home button usually gets it back on again. Sometimes the person is still on the phone because I can't hang up!
It's not the biggest problem in the world but is really annoying. Does anyone know what causes it? Is it a software issue or something to do with the hardware? Also could it be because it's re-manufactured or have people had this problem with new ones?
Thanks for any help
Edit: forgot to say it doesn't happen with every call but happens at least once a day
