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: 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.
