Good morning all, New to the Samsung / Android family - had a ipad but was looking for a tablet that had a pen... so I purchased the Galaxy Note 10.1 and I was impressed with the s pen... I purchased my galaxy in early November and configured the unit without an issue. I had it charging from the power charger and my pc, without an issue... Then in mid November, I turned the unit on and it asked it had a software update; which I let it do... it took about 10 minutes and all looked good... I then needed to charge my unit, and noticed the red x on the icon (regardless whom was charging the unit - power charger or PC/USB).. I noticed if I left the unit on, the charge would take for ever but it would charge. I turned the unit off, and connected to the power charger and the battery icon appeared on the display and I would leave this over night an the unit was fully charged. My question, before the software upgrade everything was great and after the upgrade I started to have this issue... Could this software upgrade cause this issue? Thanks in advance...
