Some devices with integrated storage have abandoned the distinction between the application area and
the content area when it comes to a Factory Data Reset. As a result, there is no option in such devices to
perform a Factory Data Reset and preserve content. In such devices, all content is completely deleted
from the device when a reset is performed.
In contrast, Sony Mobile’s memory integration solution makes it possible to preserve user content in this
situation. Therefore, when performing a Factory Data Reset, the default action will still be to only remove
applications and their data, and an option box must be checked if all content is to be removed as well (as
might be desirable when selling the device second-hand).
Note 3:
For a developer, it is important to note that from a programming 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 applications (“/
data”) is still present, as is the area used for content (“/sdcard”).
In reality, “sdcard” is a “symbolic link” to “/data/media”. However, from inside an Android application, “/
sdcard” can still be used. For example, you can use “sdcard/DCIM/100Android” to find all camera
images. The continued use of “/sdcard” to access the content area ensures compatibility across different
products and Android releases in this regard.
