There is a vital feature that Sony Engineers refused to include in their early 2012 flagships and it is called mass storage mode. In its place, we have MTP. While MTP has its advantages over USB mass storage, the exclusion of a USB Mass storage left many users unfulfilled. For various reasons, there should be USB mass storage mode for Xperia 2012 phones. This is because USB mass storage is faster than the MTP mode.
Another point is that, MTP mode tends to screen the data you are trying to transfer to your device for compatibility issues while USB mode offers you unlimited freedom to transfer data from, and to your device with amazing speed. But all things aside, in the course of the article, I shall be enlightening you with the awareness of an app called “SD Mounter” by an XDA Senior Member DooMLord. This android application enables the mass storage Functionality on the Xperia S, P and U, acro HD SO-03D and other 2012 Xperia phones lacking the features running on Android Ice Cream Sandwich and Jelly Bean.
USB Mass Storage Mode for Xperia 2012 Phones
SD Mounter allows users to easily activate either mass storage mode or media transfer mode. A rooted device with busybox is required for it to operate properly, so don’t be surprised when SuperUser prompts for root permission. As with any mass storage device, it is also recommended to eject your device from your PC once you’re done your business before you switch back to media transfer mode to prevent any unwanted storage errors. For the changelog and further information,, be sure to check out the SD mount original thread for more information.
