I have recently changed number, but kept the same device (Sony Xperia XA1). With the previous number, I saved my contacts in Google Contacts.
Before I changed the sim on my device, I erased some contacts from Google Contacts. I formatted the phone and reinstalled applications, logged in with the same google account.
Those "unwanted" contacts are still there. Even though I erased them from Google Contacts website (and I checked the website, they are no longer there).
I tried to log off that google account and in again, because I thought it was a matter of synch. But nothing changed.
So my question is, how to synch the contacts on my Android with just the current contacts on Google Contacts?
