AutoFill is a service that helps us to fill out forms automatically. when we visit a web page and enter our address in a form, we can have this data saved. the next time we call up such a form, the data can be automatically inserted.

On the Oppo smartphone, Google's AutoFill service is set as the default, but if this service is not desired, another AutoFill service can be selected or deactivated without any problem.
