In short

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 can no longer use it to show you personalised ads.

The advertising ID is an ID used only for ads, supplied by Google Play services, and you can reset it or delete it. Resetting it gives apps a new ID; deleting it removes it, and apps that ask for it then get a string of zeros. The two buttons sit side by side and do quite different things.

6 of 6 steps show a real screenshot from our Galaxy A57 5G (One UI 8.5) and Galaxy S26 (One UI 9.0).

Steps

0 of 6 steps
  1. 1

    Open Security and privacy

    Open Settings and tap Security and privacy.

  2. 2

    Tap More privacy settings

    Scroll down and tap More privacy settings.

    On our Galaxy it is the last row in the Privacy section, below Controls and alerts.

  3. 3

    Tap Ads

    Scroll down to the Google heading and tap Ads.

    On our Galaxy S26, Ads sits between Permission manager and Usage & diagnostics.

    Reset the ID

    Tap Reset advertising ID. The screen says this generates a new advertising ID that apps can use from now on.

    Or delete the ID

    Tap Delete advertising ID instead. Apps can then no longer use this ID to show you personalised ads.

    Google's Play Console Help says apps that ask for a deleted ID get a string of zeros.

  6. 6

    Confirm the delete

    Delete advertising ID opens a page that says apps can still show you ads, but they may not be as relevant, and that you can always get a new advertising ID later. Tap Delete advertising ID at the bottom. We left with Back, so nothing was deleted.

If you do not see this option

  • More privacy settings is not on the first screen On our Galaxy it is the last row of Security and privacy, under the Privacy heading below Controls and alerts. Scroll right down.
  • Ads is not near the top Ads is under the Google heading on More privacy settings, below Samsung's own options such as Send diagnostic data. On our Galaxy it is just above Usage & diagnostics. Source: Advertising ID

If this does not work

  • Apps still show ads The delete page on our Galaxy says apps can still show you ads. Play Console Help adds that individual apps can have settings of their own, and those can change which ads you get too.
  • You are unsure what reset did Reset advertising ID does not turn tracking off; the Ads screen says it generates a new advertising ID that apps can use from now on. Use Delete advertising ID if you want apps to stop using it.
  • You changed the debug option by mistake Don't worry, it is easy to undo. Enable debug logging for ads is a separate switch on the Ads screen and has nothing to do with resetting or deleting. On our Galaxy it was off; tap it again to switch it back off.

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.

On our Galaxy, the Ads screen lists three options: Reset advertising ID, Delete advertising ID and Enable debug logging for ads, which was switched off.

Play Console Help calls it your device's advertising ID.

The screenshots are from a Samsung Galaxy S26 with One UI 9.0 and Android 17, in Dark mode, apart from steps 1 and 2, from our Galaxy A57 with One UI 8.5. On some older versions of Android, Play Console Help gives the path Settings, Privacy, Advanced, Ads, with a switch called Opt out of Ads Personalization. Our phone's ID is blurred. We only looked at these screens and changed nothing.
