Meta/Facebook preinstalls an app called Meta Services (previously Facebook services) on a very large percentage of android devices (I’ve never used one without it) and while they claim it helps updates and synchronisation between different meta apps, it is very suspicious. Why preinstall it on devices of people who will potentialy never use a single meta app?
Go to your app list/app management and show system apps and find anything with the words “meta” or “Facebook” then turn off network access for those apps (if you can) and disable them. (eg. Meta app manager, Meta app installer).

Edit: Looking around I have found several people complaining that this app is using their ram for 10 hours a day even though they don’t use anything Meta. That’s even more suspicious.
Honestly, if I have the choice, I will choose Google to keep my data over Facebook/meta. While they will do the same stuff with it, at least they give me good products in exchange for my personal life. I also think Google is more transparent about how they collect their data and they let you pretty easily opt out of most of the very intrusive stuff. I also trust their security a whole lot more than Meta’s as they are pretty innovative in that space (like with webauthn)
That’s always been my only reason for holding google to a different standard. I know what data they harvest and see really clever optimizations and tailored experiences for me on their services. I actively see the benefit of my data being collected as the end user. I’ve ever felt that with meta products.
