My tablet is not turning off, and I cannot locate the battery on the back. It has done this before, but it finally turned off. Now, it has been at it for at least 3 hours. It is charging, and I also had another problem before this that I think caused it. On YouTube/Netflix it was messing with my pause/play button. I solved this by fighting back. I deleted some downloads, that did not work.Even if it fixes itself, I could use some help if it happens again. Someone please tell me what to do!!
