I had the exact same problem. Only to find out it was Flash player that I installed from the Play Store. I didn't figure it out until I installed Flash on my tablet and it started doing the same thing.It was labeled as Adobe even though I am not sure it was actually developed by them being that the had supposedly stopped support for Android.
it's happening on my note 10.1 too.. only to find out that the Flash Player 12 was the culprit. my antivirus detecting my flash player as a malware.. potential unwanted app..it suggested that I should remove it.. if i do that, what will happen to my note?will youtube works with out it? what did you do? did you uninstall the Flash player? did your tab works when you uninstalled the FP? your help will be much appreciated. thank you!
