Move Contacts to Another Account auf Oppo
On Oppo phones with several linked Google accounts, every contact stays assigned to the account it was originally created in. That single account controls which app or device sees the contact during calls and messages, even if other accounts are active on the same phone.
To reassign a contact, use the following path: Tap on Contacts ➔ Choose a Contact ➔ Open the Menu ➔ Tap on Move to another account ➔ Choose an Account.
The destination list includes every Google account currently signed in and syncing contacts on the device, plus the internal storage option. Internal storage is useful when a contact should stay local and not sync to the cloud at all.
Moving a contact removes it from the source account and places it exclusively in the destination you picked. If the same contact already exists in the target account, expect a duplicate entry rather than an automatic merge, so check for existing matches first. This method only moves one contact at a time, so bulk cleanups across many entries take longer through this menu.
