I have a very strange issue, after upgrading my phone to 4.3. After I did the official firmware upgrade via Kies, my phone appears to be taking pictures randomly. When I am using the phone, the flash just goes off, as if a picture has been taken with no input from me. These pics do not show up in the gallery anywhere. Now, I am not suggesting that Samsung is secretly gathering photos, but I am interested to know what setting needs to be changed for this to stop. Is it a notification of some kind? Just very weird to me. And on another very strange note, after the upgrade 1 of my icons on my homescreen vanished, and the strange part is, I cannot recall which one it was!!! All I know is there is an open space, where 1 did not exist previously. Ideas?
