That's why the first thing I do on my new phone is disable the Google app.
It does absolutely nothing useful for me, but never sleeps, eats resources and shows you advertisements.
I also hate the mobile apps that designed to be always on, always listening or nagging.
So, I have the policy: if the app is only useful occasionally and it is active but I didn't start it - I disable it. And I'll enable an app when I need it, not whenever it wants me to use it.
I consider any notification for something I did not explicitly sign up for an ad. So if I get a notification like "use Gemini" or "heres a tip:", that's an ad.
Unfortunately that makes, like, half the default notifications on Android ads. But you can disable all of it.
