Personalized advertising has the advantage of displaying more relevant advertising, while for the "seller" it has the advantage of a higher purchase rate.

However, it has the disadvantage that each LG smartphone (and Google account) has a unique Advertising ID that is assigned to interests and usage. If this is not desired, the personalized advertising can be disabled in the settings.

Note: Disabling only turns off the personalized advertising. advertising, but will still be displayed.
