===== FAQ =====

==== should I encrypt my phone? ====

Yes, you should. Android since 7.0 has an efficient file-based encryption method which doesn't impact performance in a noticeable way (only 3-4% speed loss). You should upgrade your phone to the latest version and check that the processor supports modern encryption and hashing algorithms.

=== how to encrypt ===

//Settings// menu → Security (wording could be different). If your device is encrypted, that's displayed here. Some devices will allow SD card contents to be encrypted, by default Android just encrypts on-board storage.

If the device isn’t encrypted, start the process with the //Encrypt phone// option.
