I have a Samsung Galaxy tablet SCH-I905 via Verizon. After a factory up grade a Red X appears on the battery when I plug in the charging cable? Also sometimes I see two USB symbols other times I see only one. After the Red X, the battery drains very quickly and it takes much longer to charge than before. I have already performed a factory reset. No change.
If you are familiar with this issue, than please advise. If NOT than let me know so I can work with Samsung directly.
