注意
* When installing an over-the-air update, connect to a Wi-Fi network when possible. OS updates are data-intensive and will install faster over Wi-Fi. Connect your phone to a wall charger during the update process.
* Some Android updates may wipe the data off your device. Before installing an update, be sure to sync your phone with the Gmail account associated with it. Apps that have been purchased through the Android market are available for download even after a data wipe. You do not have to purchase them again.
