So I'm running Pixel 6a with GrapheneOS beta updates, I'm okay? Tho if law enforcement needs in my phone they just need to hold me until after lunch, I get pretty hungry. And those Doritos and coke they offered me sure looks tasty...
Technically, the upgrade to the Pixel 8 (or higher) would be security-wise a lot better, because they offer more memory safety (MTE), but yeah you are probably good.
