Change Contacts Name Format (First/Last Name Order) auf Oppo
On Oppo phones running Coloros, the Contacts app keeps its own name-format setting instead of pulling it from Android's system locale. This means Coloros can show first name first even if your phone language usually sorts by last name, or the other way around.
The setting controls how contacts appear across Calls, Messages, and the Contacts list itself. Switching it does not change how contacts are stored, only how the display order looks on screen.
Where to find the setting
Open Contacts ➔ Open the Menu ➔ Tap on Settings ➔ Tap on Name format ➔ choose First name first or Lastname first.
Once you confirm the option, the app refreshes the list immediately. No restart is needed.
If you only want one specific contact to display differently, this setting will not help since it applies globally across the whole Contacts app. In that case, edit the first and last name fields for that single contact instead.
