Turn On/Off Autofill Service auf Oppo
Autofill on Android relies on a single active service that stores form data such as names, addresses, and saved passwords, then inserts it whenever a text field asks for that kind of input. On Oppo phones running ColorOS, this setting sits inside the keyboard and input options rather than a dedicated privacy menu, so it is easy to overlook when you are troubleshooting wrong suggestions.
If the wrong account keeps appearing, or a password manager stopped filling logins after an update, the active Autofill service has usually reverted to Google or another default provider. Turning it off completely disables automatic suggestions across every app and browser, which helps if you want to enter data manually or suspect a service is offering outdated details.
To change or disable it, go to Tap on Settings ➔ Tap on Additional settings ➔ Tap on Keyboard & input method ➔ Tap on Autofill service ➔ Select an Autofill service or None. Choosing None stops all suggestions everywhere; picking a different service switches which app manages your saved data.
If only one specific app misbehaves, check that app's own autofill permission first, since disabling the system-wide service removes suggestions in every app, not just the problem one.
