Before Updating Your Phone
Updating your phone may result in a loss of saved data depending on the condition of your phone
(malfunctioning, damaged, water seepage, etc.). You must back up all critical information before updating
your phone firmware.
Note
: As these updates can be quite large, we recommend that you download updates over a Wi-Fi
connection.
