Use F-Droid to get Google out of the picture.
Discussion
F-DROID is a OS ?
You might want to switch to GrapheneOS if you are concerned about Google. Works well for me (all but tap to pay).
F-Droid is just a Google free "App Store"
Google previent pour tout usage d'apps ne venant pas de playstore que faire si on se retrouve à devoir acheter un nouveau smartphone tel est aujourd'hui ma question existentielle..'merci
For me the solution was to buy a Pixel phone. Flash GraphenOS to it (can be done via a desktop browser)
There are some things to get used to (like no app store) in the beginning.
Use as many apps you can via the browser. Install F-Droid from their website, you can find a lot of useful apps there (like OSM maps with). Try to get APKs for other apps directly from the creators website.
