I have had this tablet Samsung Galaxy Tab for one year and I never had a problem. I used it till reached a 60% or sometimes not even that and I plugged it to charge. It was a bit slow but ok. From the past two weeks, when it charges the percentage gets stuck on 99%. If unpluged takes ages to go down to 98, 97%. So I never know the real charge...Only a restart fixes it, but I like to leave it on stand by all night to avoid the fuss of a reboot and save time in the morning. I am not keen on a factory reset. I read over the net that it could be the charger, or debris on the USB port. Any ideas? Is there sth I can do to fix this without having to calibrate it? I don't have many apps installed and it is virus free. Any easy solution will be welcome!
