I am sharing my experience with you . Mx player is better video player application then the other app . But in my device it getting trouble otherwise it is useful app. Sometimes it shows sudden advertisement while watching any movie or any song video . For avoiding this problem we need to go offline . Otherwise it does not take to much space that the other app takes. Sometimes an audio songs were not play , so this is a another problem related to this app also it is very so to set audio and subtitle delay in this player.
