I'm have a Samsung Galaxy S3 running
Android 4.1.2 which I am trying to encrypt through
Settings -> Security -> Encrypt Device. The process I am following is described in this article at Step 2.
Upon entering the
Encrypt Device screen I am told to "Set an unlock password". How is this password set? My first guess was the Android
Screen Lock, but within
Settings -> Security I have no
Screen option as I would have expected (shown in above article at Step 1). Could this be because I am using the device without a SIM card? If so, is there any other way of using this encryption method, potentially with an inactive SIM card that is not connected to any network?
