Restore Deleted Photos and Videos auf OnePlus
On OnePlus phones running Oxygen OS, deleted photos and videos are not removed instantly. They move into a Recently deleted folder inside the Gallery app, where they stay for 30 days before being erased for good.
To bring a file back, open Open the Gallery app ➔ Tap on Collections ➔ Tap on Recently deleted. From there, Tap and hold a photo/video to select it, and Select more photos/videos if desired if several files need restoring at once. Confirm the action with Tap on Restore/Recover and then Confirm with Recover.
Restored files return to their original album in Gallery, so you can find them exactly where they were before deletion.
This method only works within the 30-day window. Once that period has passed, the Recently deleted folder empties automatically and the files cannot be recovered through the Gallery app anymore. In that case, check a cloud backup or a local backup made before the deletion, since Gallery itself has no way to reach further back.
If a photo is missing but was never actually deleted, check whether it was moved to a different album or hidden through a Gallery filter before assuming it needs to be restored.
