All right, so I opted for installing opengapps with this fantastic guide: ✏ Install OpenGAPPS (Step-by-step guide)
I would have missed FP Open OS otherwise ;-).
It turns out both apps use a google map to show the bikes/atms on the streets, I guess this is why they need some google installed on the phone.
We’ll see if I get used to the update process.
I’ve seen that uninstalling opengapps is not that easy, so if I ever can come bacl to google-free FP I’ll come back to surf the forums.
Thanks to all!
