NOTE
Your personal data from internal phone storage—including information about
your Google account and any other accounts, your system/application data and
settings, any downloaded applications and your DRM licence—might be lost in
the process of updating your phone's software. Therefore, LG recommends that
you backup your personal data before updating your phone's software. LG does
not take responsibility for any loss of personal data.
This feature depends on your network service provider, region and country.
