I am using MX player app last three to four years .this app is very useful by many ways.app interface is really nice you can easily increased or decreased the volume or brightness of the video.you can play almost any kind of video formats through this app.sound quality is nice.in the setting you can easily set your preference of choices.if you are downloading any movie or video then you don’t have to wait till finishing the download although you can stream the download file and enjoying the video.this app never let me down so I give it thumbs up.
