I’m facing some annoying issues trying to sync my contacts.
It all started when they were not syncing with my Google Account (GA) properly.
Hence, I moved all of them to the phone memory, removed my GA, restarted the phone, and added the GA again.
Now, when I try to move my contacts back, the phone simply does not recognized my GA anymore in the stock dialer (or contacts) app.
I’ve also tried downloading Google’s Contacts app, but it does not show the option to move the contacts to my GA either.
