My Galaxy Tab Pro 8.4 keeps rebooting. This happens frequently like at 97% battery capacity, then it reboots and it drops to 93% capacity, goes through the Samsung title screens, then gets to the "swipe screen", then it reboots itself again, and does this repeatedly until the battery life shows around 57%. What is wrong, has the battery built up the memory that it needs to be replaced already? Is it the tablet that is malfunctioning? HELP!!
