Leaker reveals which Pixels are vulnerable to Cellebrite phone hacking

I've set up GrapheneOS on my Pixel with 2FA fingerprint + PIN unlock. No way will anyone be getting into it without my cooperation.

My only issue was less compatibility with my local emergency services, since they can't see me on a map for some reason if I call from a GOS phone.

My solution to that was a second Pixel as an emergency phone - one with the stock OS, that I'll swap sims with and take with me when hiking, stand up paddle bording and doing other activities that carry risk. This phone has no sensitive information in it. I also have a PLB for added protection.

Is there anything actually preventing Samsung or another vendor from adopting GrapheneOS's security innovations?
