I just got a new galaxy s3 a few days ago and I have two questions. First I cant seem to get it to charge up most of the time? I will plug it in for hours and it will stay at whatever % its at or only gain a little and sometimes lose a little? Second whats the newest Android version? It says I'm running 4.1.1.. Is this the latest and if not any drawbacks to updating? Sry for the (Im sure silly) questions but I dont know much about this phone or smart phones in general! Thanks, Pitty
