The most secure phone today is a Google Pixel running GrapheneOS

How so? What have you found unusable or broken compared to normal Android?
How do you install apps? There’s no App Store. There’s no consensus about how to safely install apps. Install play store? Leaks your login info to Google. Install a clone? Leaks it to China. Install one that doesn’t? Now you lack the security signing of the play store. Install the apps directly? Apps are untrusted.
This is a valid point.
I think they are trying to fix this with Accrescent. I've always heard to use Droid-ify for open-source apps, and Aurora for apps that are only in the Play Store (it uses its own Google accounts as a proxy).
