I’m using Android Pie for this post and here’s how you can reset the advertising ID on Android:
- Open Settings.
- Tap Google, which you can find between Digital Wellbeing & parental controls and System.
- Tap Ads option.
- Now, hit Reset advertising ID, which you can find above Opt out of Ads Personalisation.
- In the pop-up, you can see this message: This will replace your advertising ID with a new random number.
- Tap Ok in the pop-up.
