An unusual glitch with FaceTime calling has popped up in the Apple Discussions forum. It appears that for some people FaceTime would bring up a random image, a user wrote:

Another poster suggested that the camera seems to be keeping random images that have not been taken before and don’t seem to originate from past FaceTime calls:

Judging by the comments, restoring the phone and manually re-installing all the apps doesn’t help. This glitch is bound to raise privacy concerns. I, for one, would not be happy about my iPhone taking pictures of me when I haven’t told it so.

Actually, this reminds me of a similar problem when the original iPhone was released… Back then, eagle-eyed users had found out that the device grabbed a screenshot of the running app when the home button was pressed. This was by design so that the phone could zoom in to the saved screenshot when a user runs the same app again in order to give the appearance of loading more quickly.

The “feature” got substantial air time due to privacy implications. For example, someone could obtain your personal information by grabbing a screenshot of your banking app from the phone’s memory.
