Encryption
You can encrypt accounts, settings, downloaded apps and
their data, media, and other files. After encryption, you must
enter the PIN or password you set each time you turn on your
phone. You can also encrypt information stored on an
optional installed memory card (not included).
Encryption may take an hour or more to complete. Start with
a charged battery, and keep the phone on the charger until
encryption is complete. Interrupting the encryption process
may result in the loss of some or all data.
