I have had Google as an app disabled for the past 2 months. I don’t use google assistant or anything like that and I have had no issues. I’m not going to uninstall the play store, google play services or carrier services since I know those are pretty much integral to my phone.
I’ve used ADB to uninstall the vast majority of the bloatware or other software on my Samsung phone, but I’m not sure if uninstalling Google will actually cause my device to become inoperable.
There is no point disabling the google app when the rest of the phone runs on Google services, and the rest of the google apps. The tracking will happen regardless. If you don’t want to be tracked by them, you need a de-googled version of Android, that doesn’t run their apps, or their services. I’m currently using /e/ OS, an Android de-googled fork, by Murena: https://murena.com/ on an older Motorola G7 Plus. No google apps, and I make a point of not installing any popular app that depends on google’s services. I only use open source apps found on the f-droid open source store. Yes, that means that you won’t have games, or FB or IG, or twitter (unless you use them via the browser). But I don’t need any of that. I now only use fediverse open source apps, plus the basic phone apps found on the Murena eOS, like email and notes.
