These past 2 weeks, my Samsung S3 has taken to disconnecting itself while charging. I've woken up with a dead phone multiple times in the short period of time. It can be securely in the phone, but it's almost as if the phone isn't registering that it's connected. I've tried a different charger, and it still happens. I have a second battery that I can try, but it doesn't seem to be a battery issue because if I can get it to charge, it will usually last all day.
Any advice on what to do with this?
Also, I can upgrade soonish, but I am trying to hold off until my tab balance is at 0. (Which will be a few months from now).
