I'm running 6.2.1, everything works that I can tell, it's just my youtube is not working properly. When set on HQ setting, I can hear the video but get no picture. If I revert to low quality, I get video. I then push HQ button once video is playing, but my picture freezes. I have rebooted, and uninstalled and reinstalled youtube, but still no fix. Anyone also experiencing this or have any suggestions?
