I’m running a Pixel 7 with graphene too, but have never had any issues with the fingerprint reader. Where would an ultrasonic improve over the current version?

(Genuinely looking to understand, fingerprint sensors aren’t something I’ve thought much about!)

Thanks for that - I’m on mobile, so not entirely sure what went wrong!

Annas Archive is usually my go-to for books, and a lot of other things to be fair!
