Maximizing privacy on Android without custom ROMs?
I've had a Galaxy S22+ for 2 years and still want to use it. When I look up how to maximize privacy on Android, many results say to install custom ROMs which I can't since its a US model and the bootloader is locked. I just want to minimize tracking and sharing of personal information. I could use a firewall app like RethinkDNS to block trackers, but could I completely block tracking from Google and Samsung? Are there any lists of packages to uninstall to improve privacy? (I've used ADB to remove a bunch of bloatware. Ex: pm uninstall -k --user 0 com.samsung.android.arzone)
What I did on my old Oneplus 7t (from a fresh install) was using Shelter to create a work profile and keep anything google related there. On the main profile I didn't sign in to google or installed any google apps. I also disabled all OEM bloatware and apps I didn't use. Not ideal, but better than nothing and all I could do before getting a new phone without unlocking the bootloader.
The reverse may be a better option(?), as you can completely remove / disable ALL google services (google play, google play services, google framework, etc.) within the work profile
