It's been a couple years since I tried the graphene camera, but (at the time) it's essentially trash in comparison to the Google camera. I just use the gCam without internet permissions and call it a day.

But I'm not hardcore tin-foil 'the NSA will use your office mirrors reflection to precisely heat up a 2mm space on the side of your phone that somehow enables Bluetooth and with that the G + glowy bois will exfiltrate your data at 10Kb/s'. I want additional security hardening and some privacy additions, but I also use the play services and store, like a typical user. Yada yada threat model yada yada - I just want my phone to simply function at the end of the day. Middle of the road, if you will, between stock os users and the guy that's now boarding up all his windows because of the 2mm Bluetooth mystery vulnerability.

Unknown about the claimed AI features - my 8 pro is in transit. But I can check in a few days, if interested.
