To facilitate the transfer of data via a cable, the Xperia™ SP supports the Microsoft standard, Media
Transfer Protocol (MTP), which makes it possible to easily transfer content back and forth between your
phone and a Windows PC. For Apple Mac computers, a special application, BridgeforMac, is available
offering built-in support for MTP; this application can be downloaded from the Xperia™ SP Support page.
Note that you do not need to back up or make a copy of applications that you have downloaded from
Google Play™*. They can normally be downloaded again if, once you have set up your Google account to
work in a new phone (or a phone where the memory has been completely erased).
Note 1:
As noted above, some Android phones, including Sony Mobile devices from 2012, and Sony Ericsson
devices from 2011 and earlier, do not use a single “Internal Storage” for both applications (and their data)
and user content. Instead, these devices use either an external SD card for user content, or a
corresponding area of internal memory to reproduce the functionality of an SD card. In such devices, there
is a fixed limit between the application area (“/data”) and the user content area (“/sdcard); with the result
that user content can be filled, stopping the taking of new pictures for example, while there is still
considerable free space in the application area; or vice versa, stopping the download and installation of
new applications even though there is free memory in the content area.
Note 2:
Some devices with an integrated storage have abandoned the distinction between the application area
and the content area when it comes to Factory Data Reset. As a result, there is no choice to do Factory
Data Reset and preserve content; in such devices, all content is mandatorily and completely deleted from
the device when a reset is performed.
In contrast, Sony Mobile has done the integration in a manner which makes it possible to preserve user
content in this situation; therefore, when performing a Factory Data Reset, the default will still be to only
remove applications and their data, and an option box must be checked if also all content is to be
removed (as might be desirable when selling the device second-hand, for instance).
Note 3:
For a developer, it is important to note that from a programmer’s point of view, the location names used to
refer to the different memory areas described in Note 1 are still valid; i.e., the area used for application (/
data) is still present, as is the area used for content (/sdcard).
In reality, “sdcard” is a so-called symbolic link to “/data/media”, but from inside an Android application, “/
sdcard” can still be used (for instance, use “sdcard/DCIM/100Android” to find all camera images).
Continuing to use /sdcard to access the content area ensures compatibility across different products and
Android releases in this regard.
