Reset Advertising ID auf Oppo
Every Oppo phone running Coloros generates a unique Advertising ID the moment ad services first request one. This ID stays fixed unless you reset it manually, and it works like an anonymous fingerprint that ties your app usage and browsing habits together for ad targeting.
Turning off interest-based ads in the ad settings stops personalized ads from showing, but the ID itself keeps existing. Resetting it breaks the link between your past activity and any new ID that gets generated, so advertisers start building a fresh profile from zero.
Where to find the reset option
Go to Settings ➔ Privacy ➔ Advanced ➔ Ads ➔ Reset advertising ID ➔ OK. Confirming the dialog assigns a new ID immediately.
A reset does not delete your Google account data or app permissions. It only affects ad tracking tied to that specific identifier, so apps and settings keep working exactly as before.
If ads still feel too targeted right after a reset, check whether individual apps have their own tracking permissions active, since some ad networks use additional identifiers outside the system-level Advertising ID.
