Data-friendly YouTube Go app is available in 130 more countries

If you haven’t heard of YouTube Go before, it offers the key features of YouTube along with a lot of data management options. Users can download videos at three different quality sizes and share them with other phones without using any data at all. It also features previews, so you can check out a video before streaming or downloading it. The app itself is less than 10MB, and Google specifically made it work with slower phones with less storage, and it works on much older versions of Android — all the way back to 4.1 Jellybean, in fact. – Nathan Ingraham, Engadget
