You probably happen to have one of the CSCs that has native call recording enabled.

Everyone else needs to either root their phone or change the CSC somehow.

1. Did you install CubeACR from the Play store, or somewhere else?
2. Did you install it on an earlier Android version, and then upgrade?
3. What device is this, if you don’t mind sharing?

Do you have such a phone? What CSC does it have?

Two problems:

1. No automatic call recording.
2. Banking apps don’t work on GrapheneOS thanks to Play Integrity APIs, so you probably need to root to get them to work.

If you need to root anyway, might as well use BCR.

I very much doubt that, since Google removed the call recording APIs. But if someone can tell how it would work on recent Android, I would love being proven wrong.

Cool. Now let me legally record my phone calls without rooting my phone.

You are arguing for selective encryption, but I can’t really find any technical argument in your comment.

Whether we are speaking of encryption at transit or rest, there’s a general consensus that encrypting everything is best in every way except possibly performance for select cases.

For example, it allows hiding (meta)data about the really important bits, and with computers it’s really difficult to tell which bits of (meta)data could be combined to abuse. Tampering is a consideration as well.
