A deodexed ROM for the Samsung galaxy S5 mini is now available courtesy of XDA developers. Since it is based on stock ROM, you get same look and feel but is deodexed and thus it is better than the completely stock rom. There are two versions of it – full version and cleaned version which does not come with any add on applications pre installed.
