MrGQ in the Apple discussion board on the FaceTime bug:
I am experiencing the exact same issue recently. Most notably just minutes ago when i called my GF and i saw a “picture” of myself from today when i was at the office. I know it was from today because i had the exact same shirt. The weirdest thing is that picture is not stored on my iphone.
You may be thinking that, while this is weird, it isn’t that creepy. Nasetron adds the creepy though:
Some of the images that have been coming up on mine are from times and places when I know without a doubt that I haven’t been using facetime.
Luckily it seems the images are not being shown to any one but the iPhone owner — but still, why is it taking these pictures at all?
