Android 4.1.2 Full Device Encryption
Are you sure that you have enabled FDE? I've read this link which states that FDE may not work directly as expected (must try in 4.2.2 multiple times), and that you need a PIN or Password defined in advance. I mean, if you can access your data without entering a security credential then your device is probably not encrypted right? Watch out FDE may not encrypt all the things you think it should: Does Android&#39;s Full Filesystem Encryption also Encrypt the SDcard?
