I have an LG V20 but I can't find the setting for full device encryption. There is a setting to encrypt the SD card. However, I'd like to also encrypt any memory on the phone itself.

Is this possible in Nougat?

    Nougat doesn't offer that feature anymore. It offers direct boot which is covered here – beeshyams Nov 1 '16 at 13:35

    The encryption was never "full" - only user data and cache partition. The system itself was never encrypted. – Robert May 8 '17 at 12:50

Head to Settings > Security > Screen Lock and tap your current screen lock. If “require PIN to start device” is an option, you’re running full-disk encryption.

If you’d like to convert to file-based encryption, you can do so by enabling Developer Options, then heading into Developer Options and tapping the “Covert to file encryption” option. Keep in mind that this will erase all of your data, effectively factory resetting the device!

Here is the full tutorial from howToGeek.
