I mean you can say it’s “insecure” since Google stopped providing security patches. I don’t really care much tho, I don’t keep confidential stuff on my phone, I’m not that much of a valuable target and I’ll be pwned anyway if I get targeted due to bad opsec. I’d say my phone running Android 11 with root and everything is much more “private” than most normal Android 16 phones since I have stuff like AdAway and AfWall. Android 11 still works for most apps, I’ve never seen anything not supported.
