MixZing Player Lite was my favourite Android app because it has a great album cover feature and the ability to permanently delete tracks from my SD card (many desktop music players don't even have this). Plus it's well organised and easy to use. But recently they've updated it (which i've regretfully installed) and it's got ads all over the god damn app and some functions like searching for songs doesn't work. The worst part is the app is really really slow now, like If I press 'next track' 'next track' 'playlist' quickly, thereafter it'll change track twice and show me the playlist, plus there are plenty of 2 second delays when pressing anything in the app. My mp3 player from 2003 is faster than this. Is there anyway to downgrade/downdate to the previous build of the app?
