Has it? Does it afford me 'contextual' permissions, rather than an app just requesting contacts for no reason? Does it let me know _what_ data it's requesting (long/lat coordinates, state/county, country, continent?)? What about the data it's requesting about my contacts, does it tell me which contact's data was accessed, and what data that was (first/last name, DOB, email, phone number)? Does the app make a request to a server after getting that data, does it store it on a server? Are apps compliant with the GDPR, do they respond to privacy requests, such as what data they store, or whether they delete data when asked to do so?

Everything you see about privacy is an illusion, designed to do the bare minimum to make people think Google respects your privacy. But there's a reason Facebook likes Android simply due to how much information it gives developers with or without permission. You can hope the user allows that location permission (accidentally just once is all it takes).

Without actually detailing what information they want, why they want it, how they'll use it and how it'll be stored and processed and deleted (LOL) then no, privacy has not increased.

And this isn't exclusive to Android, but operating systems and 'apps' as a whole.
