MAY use USB mass storage, but SHOULD use Media Transfer Protocol to satisfy this
requirement.
If device implementations have a USB port with USB peripheral mode and support Media Transfer
Protocol, they:
SHOULD be compatible with the reference Android MTP host, Android File Transfer .
SHOULD report a USB device class of 0x00.
SHOULD report a USB interface name of 'MTP'.
7.6.3. Adoptable Storage
If the device is expected to be mobile in nature unlike Television, device implementations are:
[SR] STRONGLY RECOMMENDED to implement the adoptable storage in a long-term
stable location, since accidentally disconnecting them can cause data loss/corruption.
If the removable storage device port is in a long-term stable location, such as within the battery
compartment or other protective cover, device implementations are:
[SR] STRONGLY RECOMMENDED to implement adoptable storage .
7.7. USB
If device implementations have a USB port, they:
SHOULD support USB peripheral mode and SHOULD support USB host mode.
7.7.1. USB peripheral mode
If device implementations include a USB port supporting peripheral mode:
[C-1-1] The port MUST be connectable to a USB host that has a standard type-A or type-C
USB port.
[C-1-2] MUST report the correct value of iSerialNumber in USB standard device descriptor
through android.os.Build.SERIAL .
[C-1-3] MUST detect 1.5A and 3.0A chargers per the Type-C resistor standard and MUST
detect changes in the advertisement if they support Type-C USB.
[SR] The port SHOULD use micro-B, micro-AB or Type-C USB form factor. Existing and
new Android devices are STRONGLY RECOMMENDED to meet these requirements so they
will be able to upgrade to the future platform releases.
[SR] The port SHOULD be located on the bottom of the device (according to natural
orientation) or enable software screen rotation for all apps (including home screen), so
that the display draws correctly when the device is oriented with the port at bottom.
Existing and new Android devices are STRONGLY RECOMMENDED to meet these
requirements so they will be able to upgrade to future platform releases.
[SR] SHOULD implement support to draw 1.5 A current during HS chirp and traffic as
specified in the USB Battery Charging specification, revision 1.2 . Existing and new
Android devices are STRONGLY RECOMMENDED to meet these requirements so they will
be able to upgrade to the future platform releases.
[SR] STRONGLY RECOMMENDED to not support proprietary charging methods that modify
Vbus voltage beyond default levels, or alter sink/source roles as such may result in
