AC Question
My Samsung galaxy tab-3 suddenly turned on by itself when it was charging. Then the screen kept on flashing blue, and it would stop when I pressed the power off button. I unplugged it and left it for several minutes. When i checked on it again, it went back to normal, except the background has changed to the same blue it was flashing, and i can't get rid of the "device is fully charged" notification, even when the device is not charged. However, my lock screen background remained.
