I'm not sure if that's the case, Cause I recently found out. .it's not only youtube but viewing anything online with video wouldn't work. I don't know but if I don't find a solution. .I think it might be a virus idk .
Re: S6 edge+ YouTube and touch key sound problems? nothing works
I have 4g LTE and full signal bars
I watch videos in any quality but mainly 720p
