One of the major issues with the YouTube app on Android is that it only plays back HD videos if your device is connected to a Wi-Fi network. Over 3G, the app only provides the option to playback videos in “HQ” mode.
With Android devices now packing full HD and higher resolution screens, watching videos on HQ mode is quite an eyesore. At the very least, Google should provide an option to view videos in HD mode even when streaming videos over mobile network.
Thankfully, a developer over at XDA forums has released a modded version of the YouTube app that allows for 720p/1080p video playback over 3G or Wi-Fi. The app will be especially handy for DROID DNA, HTC One, Galaxy S4 and other 1080p Android handset users, where videos in HQ mode don’t do justice to the screen of these phones.
