What does it mean to encrypt your phone?

One such option is to encrypt your entire device. This means that every time you power your phone on, you’ll need either a numeric pin or password to decrypt the device. An encrypted device is far more secure than an unencrypted one. When encrypted, the only way to get into the phone is with the encryption key.

Does Android automatically encrypt?

Some devices will also allow SD card contents to be encrypted, but by default Android just encrypts on-board storage. If the device isn’t encrypted, you can start the process by tapping the “Encrypt phone” option.
