Important Connection Information
ⅷ To avoid loss of data, DO NOT remove the USB
cable, the microSD card, or the battery while
accessing or transferring files.
ⅷ DO NOT use your computer to change or edit folder
or file names on the microSD card, and do not
attempt to transfer large amounts of data from the
computer to the microSD card. Doing so may cause
the microSD card to fail.
ⅷ DO NOT turn off or restart your computer, or put it
into standby mode, while using a mass storage
device. Doing so will result in loss or damage of data.
ⅷ The internal microSD card can only be mounted for
use by either the device or a connected computer.
Prior to accessing the card via a different method, it
must first be unmounted from its current device
(phone or computer-USB).
Important: The internal microSD card can only share a
connection with one device at a time, either your
device or your computer (via its USB connection),
not both. You can not browse the contents of the
card via your device if they are currently being
browsed via your computer.
