MX player is a popular video player in the android platform. Almost all android users use this player more than the built-in players in their phones. The players lets you control many things like changing the overall theme of the player, colour of the toggle buttons, disabling the audio/video and many more. Its really easy to turn the volume up and down. Just scroll up and down it’s easy as that. Many other shortcuts are available in the app. Really a good player to watch movies from. Its really worth it.
