My Android is unencrypted and running Android 5.1. However when I restart the phone I cannot access the file system using Android File Transfer using a trusted computer unless I enter my password.
Given that my device has not enabled whole disk encryption what is stopping me from gaining access?
Do I still need to encrypt my files?
If the files are accessible how can I access them in order to test if the encryption I intend to add works?
Note: Encryption is not on by default on Android phones so I'm taking these measures to encrypt at the file level to secure the data for users who have not enabled whole disk encryption on their phone.
