File sharing
By using the Server role of the File Transfer Profile,
the phone enables the use of a computer to
manage content files that reside in the phone’s file
system. Most computer Bluetooth applications
provide an explorer-like user interface for the file
transfer service. The content in the Games and
more folder is not exposed in the file transfer
server. Opening one of the folders will show a list of
files related to that folder, such as, images in the
Pictures folder. Using the computer application the
user can now: retrieve files from phone to
computer, delete files from the phone and transfer
files from the computer to the phone using the
normal drag and drop mechanisms provided by the
computer.
File browsing
By using the Client role of the File Transfer Profile,
the phone enables the user to access file systems
of other devices, that also support the Server role
of the same profile. After pairing the phone with the
other device, the user can connect to the other
device by selecting it in the ‘My devices’ list on the
Bluetooth menu and selecting the browse option
that should be available on the left selection key. If
the browse option does not appear the user can
select the Service option to update the phone’s
knowledge that file browsing is possible to use with
the device. When the phone is connected to the file
server, the user can browse the shared folders and
retrieve files listed in different folders. Files are
transferred to the file server device using the
normal Send/via Bluetooth option.
Media viewing
The phone can send images and sounds to a
media viewer device, such as, the MMW-100 TV
adaptor accessory. The user can also conveniently
run a slide show on the TV showing a set of nice
phone camera pictures for family and friends. The
phone can connect to a Bluetooth device that can
receive images, the image can be transferred to the
remote screen and displayed.

System functions
Power save mode
The phone uses sniff mode on headset and
handsfree connections which means reduced
power consumption and shorter connection set-up
times.
USB
G900 is USB (Universal Serial Bus) 2.0 compliant,
and for the transferring of large amounts of data, a
user can select high-speed mode – up to 480
Mbps. This greatly reduces the time needed to
transfer, for example, a large number of music files.
USB in a mobile phone means a possibility of
convenient data transfer between the phone and a
computer.
At synchronization of PIM data in the phone with
the corresponding data in a computer (using PC
Suite for Sony Ericsson) USB full-speed mode, 12
Mbps, is used.
