Had pro 3 2 years haven't used it much maybe 1 hour tops, been useing my p3s, now all my video is choppy with lines going through it, when i first got it no problem at all beautiful video, always properly stored, it has the original firmware from 10/2016 and i switched phones since i have used it last( the phone i have now is not the best) and i last primarily used a i-pad mini 2 which broke. Also I'm just learning how to set the camera up that i know very little about but that wasn't an issue before, so please help if you can
