Encryption
As a security measure, you can encrypt the contents of your
phone or an installed memory card, and require a password
each time you turn on the phone or access the memory card.
Encryption may take an hour or more to complete. Start with
a charged battery, and attach the charger until encryption is
complete. Loss of power or other interruption may cause the
loss of some or all data.
Once your information is encrypted you will be prompted to
enter your decryption password each time you turn your
phone on.
