Since 2 days my Galaxy Note III is acting up. It doesn't charge anymore (when I turn it off, take the battery out and put it back in and turn it back on sometimes it DOES charge), the charging symbol is appears and disappears every 10-20 Seconds (that even happens when the charging cable is NOT PLUGGED IN). Kies and Smart Switch don't recognize the phone anymore when I connect it to the computer. I tried 3 different cables, 4 different chargers, I tried another battery - no change. The battery is drained rapidly (like 1 percent every 2 minutes). I cleaned the Micro USB port, I wiped the system cache, no change. I uninstalled a few apps (and games) right before it happened - just a coincidence? I'm thinking about doing a factory reset but I'm a little reluctant since I have a lot of stuff on there and right now I cannot backup through Kies / Smart Switch. Any suggestions / help? I'd appreciate this very much. Thank you.
