How to synchronize mobile contacts in Google address book (Google address book update adds the option to synchronize contacts stored in mobile phones)

Some people may know that Google's address book cannot choose to back up and synchronize contacts stored on smartphones. If you do not create a contact through your Google account, the contact will not be synchronized with your other contacts and will remain on your phone.

Alternatively, you can create contacts directly in your SIM card or in your phone's memory. If you switch phones, contacts stored in the phone will not be synchronized with your Google account, so you can take them with you in the easiest way.

However, AndroidPolice reported that Google has begun to introduce new "contact" updates, which seems to introduce a new option that allows users to back up and synchronize locally stored contacts. If you enable this feature through a new toggle switch in the application settings, the operation will be done automatically. This update has nothing to do with the Pixel owner, as these phones will prevent users from storing contacts directly on the phone. The new features will be extended to all kinds of mobile phones in stages. The Galaxy S10 series seems to be available on Samsung, but not on the new flagship.
