A topic over at Apple's Discussion Forums has a few users reporting an unusual glitch with the FaceTime app on their iPhone 4 handsets. iPhone 4 users are reporting that when using FaceTime, the screen shows a random picture frozen on the screen.
It seems several iPhone 4 owners are experiencing this FaceTime glitch, which is increasing privacy concerns among the community. According to several users, the camera seems to be keeping random images that have not been taken before and don’t seem to originate from past FaceTime calls.
