“For device implementations supporting full-disk encryption and with Advanced Encryption Standard (AES) crypto performance above 50MiB/sec, the full-disk encryption MUST be enabled by default at the time the user has completed the out-of-box setup experience.”
What is Full Disk Encryption?
- The private user data partition (/data)
- The public data partition (/sdcard)
What’s the Problem with Full Disk Encryption?
- Slower Performance: As mentioned above, Encryption always adds some overhead, which causes your device a bit slower.
- Encryption is One-Way Only: If you forget the decryption key, you’ll need to factory reset your device that will eventually erase all the data stored on your phone.
