I managed to get it working, downloaded last full rom from recovery using wifi and did a factory reset. The problem was i downloaded google play apk form web (i think). With the last rom clean, i downloaded the google play from vivo app store and then managed to get google contacts working.Good Morning
To sync your Gmail contacts you need to download "google contacts Sync apk" from the web.
The idea of overwriting the global version with Funtouch OS is a very good one. However Origin OS works fine with the latest Vivo updates.
Just run adb to disable Chinese bloatware.
The only thing I really miss is Android Auto and that the preloaded application cloning app (Settings / Applications and permissions / Application cloning) is compatible with WhatsApp.
The latter I could solve with WhatsApp Business.
The Android Auto bug with the floating window permissions I could also fix it using adb but unfortunately there is no connection with the vehicle's infotainment system.
Has anyone got a solution?
