If you’re aiming to not send any data to google, you may also want to double check that Google DNS servers aren’t being used, and you’ll need to reconfigure the captive portal check not to connect to google servers every time you connect to a wireless network.
Note that currently Fairphone Open aims for maximal code transparency and not necessarily maximum Google independence, which is difficult as Google is the main developer of Android (and issuer of security patches!). Also, the Fairphone developers (or any Fairphone staff, for that matter) don’t read all the posts on the community forum. So it’s fine to discuss things here, but if you need an official response you will need to contact Fairphone directly.
