there's not that much hardening that can or needs to be done
4G provides less precise cell tower triangulation data than 5G, you can change it but it will be slower
The profiles can still be linked through the Media ID for antipiracy, i am not sure what it's called, and canvas fingerprint can still look unique in Vandium, people will get deemwd unique at eff.coveryourtracks.org, the last time I checked and people on here talked about it. The point is the phone is still linked to you once you log into anything KYC linked, lile amazon, and they can sense it's you after that in any profile often. Graphene is out of the box very secure, it's harder to hack, according to many, although I lack the technical skills to be sure and am just trusting others. It is not out of the box anti-tracking if you go to websites woth trackers or install apps with trackers. It's less bloated and you'll have more control. It doesn't make you invincible, it's just better than iOS and the bad one.
