I bought my tablet in November and love it. The battery doesn't stay charged as long as I expected and using it constantly I am frequently re-charging. I started having trouble with charging about 6 weeks ago and it would get to about 60 to 70% and then stop charging. If I tried to work on while charging, it seemed to drain the battery instead of continuing to charge. I bought a brand new charger from Samsung and at first, it was great. Now only 2 weeks later it is doing the same thing again. I can leave it charging all not and it won't completely charge. In addition, it seems loose in the connection where you hook the charge into. Any ideas?
