If an AutoFill service is used on the LG smartphone, it is possible to store login data such as user name and password or even entire addresses. The device then recognises forms and can automatically fill them with the data. By default, the Google AutoFill service is activated on LG devices. In addition to these, other services can be added or the AutoFill service can be switched off completely.
