Nah, not scanning at the bottom of the screen. It's just the little black box thing in the centre. Pops up every three seconds, as though it's loading something. Sorry, picked up "scanning" from a previous post. LOL.
I've removed the Facebook app, as that was the only app that has been logged into all the time. I haven't touched the others in weeks so I'm doubting they're the problem! so far, it hasn't happened again, and has been six hours.
