Set a lock screen PIN or password before starting encryption. Fully charge the battery and keep
your phone connected to the power adapter during encryption. This process may take about an hour
or so.
You cannot undo encryption on the phone storage. If you want to return to an unencrypted phone,
you must perform a factory reset. Once you enable storage card encryption, only new files added
after encryption will be encrypted. Files already on the card will not be encrypted. Also, storage card
encryption doesn't reformat or erase your card. Encrypted files on the storage card can only be
opened by the phone that encrypted them.
