I have to agree with mid-kid here. GrapheneOS is great for security, but some of that ends up directly in conflict with privacy.

For example years ago I opened an issue around runtime-patching applications (https://github.com/GrapheneOS/os-issue-tracker/issues/284) and was told it didn't make sense in the OS.

Putting aside the validity of arguments on either side of that issue, runtime patching allows me to very quickly excise large swaths of anti-privacy code across every app on my phone.

If I was to switch to GrapheneOS I'd have to accept that I'd be giving up a fair amount of privacy for the added security.
