PopPlayer

PopPlayer is a powerful video player that lets you play videos stored on your Android as well as ones streamed from YouTube or other online video sources.

The best thing about PopPlayer is the huge number of options you'll have during playback. You can change the speed of the video with just a swipe forwards or backwards on the screen and also raise or lower the volume or even make the video go backwards (as if you were rewinding it).

Another interesting tool included in PopPlayer is its excellent support for subtitles, which lets you not only upload files but also choose the size and color of the font on the screen.

PopPlayer is a powerful video player that includes many more features than the default video player for Android. Its interface is not only quite elegant but also perfectly adapted to touchscreens given its very intuitive gesture shortcuts.
