General sync settings11.7.1
Background data
Mark the checkbox to permit applications to synchronize data in the
background, whether or not you are actively working in them. Unmarking
this setting can save battery power and lowers (but does not eliminate)
data use.
Auto-sync
Mark the checkbox to permit applications to synchronize data on their
own schedule. If you unmark this setting, you must touch an account in the
list on this screen, press Menu key and touch Sync now to synchronize
data for that account.
Synchronizing data automatically is disabled if Background data is
unchecked. In that case, the Auto-sync checkbox is dimmed.
Manage accounts11.7.2
The rest of this screen lists the Google Accounts and other accounts
you’ve added to the phone. If you touch an account in this screen, its
account screen opens.
This screen contains different options, depending on the kind of account.
For Google Accounts, it lists the kinds of data you can synchronize to the
phone, with checkboxes so you can turn synchronizing on and off for each
kind. You can also press Menu key and touch Sync now to synchronize
data. Touch Remove account to remove the account along with all its
data (contacts, mail, settings, and so on).
Privacy11.8
You use the Privacy settings to manage your personal information.
Back up my data
Mark the checkbox to back up your phone’s settings and other application
data to Google Servers, with your Google Account. If you replace your
phone, the settings and data you’ve backed up are restored onto the new
phone the first time you sign in with your Google Account. If you mark this
option, a wide variety of settings and data are backed up, including your
Wi-Fi passwords, bookmarks, a list of the applications you’ve installed, the
words you’ve added to the dictionary used by the onscreen keyboard, and
most of the settings that you configure with the Settings application. If you
unmark this option, you stop backing up your settings, and any existing
backups are deleted from Google Servers.
Automatic restore
Mark the checkbox to restore your backed up settings or other data when
you reinstall an application.
Factory data reset
Erase all of your personal data from internal phone storage, including
information about your Google Account, any other accounts, your system
and application settings, and any downloaded applications. You can also
mark the Erase SD card checkbox to erase all the data on your microSD
card, such as music or photos. If you reset the phone in this way, you’re
prompted to re-enter the same kind of information as when you first
started Android.
When you are unable to power on your phone, there is another way to
perform a factory data reset by using hardware keys. Hold down Volume
up key and press Power key at same time until the screen lights up.
