I don’t like latest YouTube application on Android. Why? The last few versions have serious video quality issue. You can easily spot on 1080p screen like Nexus 7 (2013). Therefore, I uninstalled all the updates and use back the stock YouTube version. However, after upgraded to Android 4.4 KitKat. The stock one was replaced with this poor quality version. So no more nice music video for me until I discover Viral. Basically, it is a YouTube app with pop-up video feature. Not perfect on Nexus 7 (2013) as it still have soft navigation bar even on full screen mode. But at least the video quality is better than stock YouTube on 720p.
