Hi! so i got a Samsung Galaxy s3 in late June and for the first month, i loved it! it was a really great phone, but then about a month and a half later the phone started to charge really funny. i tried buying new chargers, only one of them worked, and it wasn't even made for a samsung, it was for for an LG.That charger worked pretty good but eventually it got worn out. I decided to go back to the charger that came with my samsung, it works but it charges very slowly and the percentage goes down abnormally fast. I even tried switching batteries, that didn't work either. I also tried restoring my phone to the factory version, that didn't work either. please help.
