I got the tablet for Christmas 2016. Recently When I use it while it is charging. the screen goes berserk. It constantly moves up and down, zooming in and out with no rhyme of reason, and when I'm typing I will randomly puts another letter, and when I try to get rid to the letter it adds 2 to 5 other letters (this also counts the enter button). But when I'm not charging the tablet it's perfectly fine. I don't know what is wrong with my tablet. For the record there are very little scratches and cracks on my screen. Now I just realized that this is only happening on the right side of my tablet, but I still don't know what to do.
