I have a Galxy Note Pro 12.2, SMP-900 that discharges even though the charging adapter is plugged in. Have tried several things to resolve the issue, including restarting the tablet, turning off all but essential apps, swapping charging cables and adapters with my Galaxy S5. Charges while device is turned off, but very slowly. Problem seems to have started after upgrade to android 5.0.2. Had no problems before that. Additionally, the charging indicator will disappear intermittently and return a few seconds later with a pronounced "beep". Is anyone else having this issue with this tablet? Any suggestions how to resolve the issue short of doing a full reset. Have a lot of data on the tablet that I don't want to lose. Thanx.
