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.
While technically it is, it mostly depends on whether you use Google products. I use some of them, but not all of them so the ones I don’t use I still consider bloat personally. Regardless of how I feel about it though anything pre-installed that you can’t uninstall is bloat and Samsung, in my experience, is the fucking worst I’ve used.
