I have done some searching and haven't been able to find anything on this issue. When my P3S is on and I pick it up and turn it on it's side, the camera starts to go crazy and zips all around. It also keeping going into ATTI mode and announcing it audibly through my ipad. It will keep repeating this sequence until I turn it back upright. Obviously I don't always carry it like this, just made me wonder what is going on with it. Thoughts?
