In some latest android smartphones and updates some of the manufactures not includes the USB Mass Storage mode. They prefer to include MTP ( Media Transfer Protocol ) over UMS. Even MTP have its own advantages, many users still prefer UMS.
In Xperia S, P and U Sony not included the option to enable USB Mass Storage. But still we can enable the UMS using the third party app SD Mounter. The app requires Rooted Stock Ice Cream Sandwich or Jelly Bean with Busybox installed. Now this app tested with Xperia S , P and U and works well. Check with other Xperia devices and share your feedback.
