Open Settings, Security and privacy, More privacy settings and tap Ads. Reset advertising ID gives apps a new ID from now on; Delete advertising ID removes it, so apps that ask get only zeros.

Step by step
Open More privacy settings
Settings, Security and privacy, then scroll to More privacy settings.
Tap Ads
It is near the bottom, under Google.
Reset it
Reset advertising ID creates a new ID that apps can use from now on.
Or delete it
Delete advertising ID removes it. Apps that ask for it get a string of zeros, so they cannot show you personalised ads based on it.
About this guide
Apps use the advertising ID to link what you do across apps for personalised ads. Resetting it breaks that link; deleting it stops apps from getting one at all.
The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ. Our phone's ID is blurred. We only looked at these screens on our phone and changed nothing.
Good to know
Samsung's own options are higher on More privacy settings, such as Send diagnostic data.
Deleting the ID does not remove ads. You still see ads, only less personalised ones.
In short: Settings, Security and privacy, More privacy settings, Ads: Reset or Delete advertising ID.
