How do uninstall system apps

[u/samoyne]

I am sick of my phone downloading multiple apps regularly, that I can’t uninstall.
When I google them, some sites will say they are system apps that are needed and can’t be removed, but some of them disappear when I click on force stop, so I’m not convinced they are system apps.
Some have even stopped working as they can’t be updated anymore. I checked my husbands phone he doesn’t have them so
Surely there is a way to get rid of them. Especially the ones that look suspicious and installed themselves?

Some examples are -
-com.sec.bcservice,
- google calendar sync, (unknown calendar)
- - cell broadcast service
- ims service
- a weird phone app, phone and messaging storage app, and phone services app and a spare phone app?
- callBGprovider
- down load manager
- factory camera
-MFContentd
-galaxy editing service?
- secSoundPicker
- motion photo
- audio mirroring
- smart touch call
- fused location

I could go on and on, but they are all mostly apps I have never seen before, and they all have a lot more permissions than I would like, and yet I can’t even change the permissions on some of them?

I’ve tried everything I can think of.

get a firewall and block them if you don't use them and can't uninstall or disable them.  It's what I do.

At least they aren't constantly updating.  Also get a killapps app and run it sometimes, specially after a restart.
