I'm not totally sure I barely use Google Messages except for verification codes, I prefer to uninstall it preventing it from having any access to my local end to end encrypted keys for other apps. but it's up to you I guess.
I use YouTube Music installed as a brave app with ads block on. I'm always connected to internet so I save storage space and time watching ads.
The other one is Android System Key Verifier, for that I'm not totally sure it's malware but as it have access to your end to end encrypted keys and the way it's secretly installed seems shady to me. Looks like a way for Google to intercept end to end encrypted messages for me.
Client side scanning, it's already happening in android running google services there are two apps automatically installed which at least I know scan photos in the device. One is android system saftycore and the other I can't remember the name.
I can't understand why people can't use their devices whatever the way they want, greedy corps.
