How to sync contacts with Google?

Your Google contacts sync to your Android device when you sign in. Changes to your contacts will automatically sync to keep them backed up and up to date. If multiple Google Accounts are signed in to the same device, Google contacts from all accounts will sync to the device.
To scan and connect the nearby device using Google Fast Pair, please refer to the following steps:
1. Open the [Settings] APP;
2. Swipe down to find and select [Google];
3. Tap [All services];
4. Select [Google Contacts sync];
5. Tap [Status] and enable [Google Contacts sync];
6. Tap [Notifications] to configure the settings for syncing contact notifications.
Note:
1. If you use a work or school Google Account, download the Contacts APP to get all contact details, like job titles;
2. When you use the Contacts APP without an account and turn sync back on, it will make your Google Account and your contacts available in the APP.
