Hypatia is interesting, but you might not need to have it running permanently.
If your Samsung is fresh off the shelf, there is likely some bloatware on it. Apps that canot be deleted.
If you are very serious about being a little more private and a little more secure, you could do some of the following.
- factory reset your device and then use adb (or the Universal Android Debloater https://github.com/0x192/universal-android-debloater) to remove the recommended Google and OEM apps.
- factory reset optional
- you won't be able to remove trackers, and some of them are just there for bug reporting. Being aware of them is good. There are several apps that can prevent the trackers from reporting (Tracker Controller, host blockers like InviZible Pro, etc.)
- practice good habits: 2FA (Aegis) and password management (Bitwarden), avoid using biometric data when you can, E2EE, etc.
- change email providers (maybe)
Take it slow though. There is a reason why they call this a rabbit hole and it can be daunting to figure it all out.
