Update Your Phone
From time to time, updates may become available for your phone. You can download and apply
updates through the Settings > System updates menu.
Software Update Cautions
During update: The phone cannot be used until the software update is complete. It may take
time to update your phone's software.
Signal during update: Update your phone where signal reception is good, and do not change
location during the update process. Make sure the battery is adequately charged before
beginning an update. A weak signal or low battery during an update may cause the update to
fail. An update failure may disable the phone.
Other functions during update: Other phone functions cannot be used during a software
update.
Update Your Phone Software
You can update your phone's software using the System updates option.
