I have seen some other posts on this before but they all suggested disabling hardware overlays. The problem is that occasionally, after some time, the video player on the note 10.1 2014 (or any video on full screen for that matter) has this really weird graphical glitch where everything just flickers or freaks out. It is not just the video but the entire screen just glitches while the video is playing. Now disabling H/W overlays does work but the problem is that it completely slows down my device and makes it really laggy rather than the normal snappy feel after the kit kat update. I had to return this thing so many times and I don't want to return it if I don't have to but I rather have a functional device rather than one that will die later. The problem fixes itself when I restart the device. But apparently it is due to some issue with the device not recognizing whether to get the video from the GPU or CPU or something like that. It is just really annoying and I just wanted to find a way to fix it maybe by updating the full screen video thing or anything at all. Otherwise I would want to return it. If everyone else has this problem then I figure it is because of the update, but if some of you don't then I think it is something with my device rather than the software. Any help would be appreciated. Thanks!
