YouTube for Android has finally been updated with a Material Design interface for devices running Lollipop. The entire app has been redesigned, from the “What to Watch” screen to individual channel and video pages.
Aside from the new design, the updated app also includes many new filter options for searches, allowing users to find videos that meet specific criteria. For example, you can now search only for videos that are available in HD, or have closed captioning enabled. You can also search for live streams.
Update: The redesigned app should be rolling out on the Play Store as of Wednesday, December 10th.
