For signatures you can use a dedicated signing subkey, however you get in problem with encrypted emails as mobile devices are not really secure devices and should never have cryptographic material. What could work in this case is a NFC (or for that matter bluetooth, although it needs to be properly paired etc etc) channel with a separate device with a separate keychain and display so you can verify the request, and never

This should read pinentry, the existence of a keyring is implicit to the use case..
