Restore Deleted Contacts from Trash Bin auf Oppo
On Oppo phones running Coloros, deleted contacts don't disappear instantly. The Google Contacts service keeps them in a trash bin for 30 days before permanent removal, the same mechanism Android uses across devices with contact sync enabled.
This only works if sync was already turned on when the contact was deleted. If sync was off at that moment, the entry was only removed locally and never reached the cloud-based trash bin, so it cannot be pulled back this way.
Recover a contact from the trash bin
Open Tap on Contacts ➔ Open the Menu ➔ Tap on Trash. Find the entry, then use Tap and hold a Contact. Add more entries with If desired, select other Contacts. Finish with Open the Menu ➔ Tap on Recover to move everything back into your active contact list.
Recovered contacts return with their original numbers and details, but linked call logs or message threads may need a moment to re-sync. If more than 30 days have passed, the trash bin no longer holds the entry, and a Google account backup or manual re-entry becomes the only remaining option.
