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)
You should use a VPN or an tracker blocker like DuckduckGo. This is the only way to slow down the information you are sending out. You might not be able to completely stop Google and Samsung from tracking you, but there’s no reason to share yourself with all other data harvesting services.
You have to obfuscate the info that makes it through by using multiple, unlinked Google accounts that let you put separate components of your life into separate silos.
