I bought a Nokia X6 phone from China with Android V8 OS. Few days ago my phone upgrade Android 8 to Android 9 and after up gradation Google is not syncing contact details from server. However, in Android Version 8 everything was fine. I had checked every options related with contact sync function, but I found that this feather is not there to sync contact from Gmail. Now I am in big trouble. I need to read and write all contacts to my phone. Please give me full solution to get rid of this issue.
