After Rooting the t800 I have had battery issues charging takes too long so far I have left my tablet on charge for 6 hours and battery is only 15% I have checked all plugs cables they all work fine. What can be the issue? The knox has been tripped to 0x1 also I have hard resetted the tablet back to original firmware...still same issue. When I plug in via usb cable pc or laptop I get a red cross symbol before I never did get that. Can I send it back to Samsung for replacement repair? So annoyed! should not of done a root
