Mx player is the video player I used too.it is very simple to use, very attractive, even a small boy can use it without enough knowledge about it.but the problem is when ever I connected to internet it shows ads videos.etc.if we accidently touch it it will go into another webpage Mx player began to hang when ever I connected to internet, it takes minutes to show videos and some audio codec ac3 codec are not supported in mxplayer, we need to install it separately from playstore or we need to play video in other players like vlc.etc
