Do you know how to recover deleted photos videos from samsung galaxy s21? I lost some videos and photos from my S21 and want to restore them.

If you have backed up your videos using some cloud services like Samsung Cloud, Dropbox, etc. then you can directly get your deleted videos back by extracting them from the backup.
If the above way fail to help you out, there’s the last choice for you to get deleted videos and photos back. MobiKin Doctor for Android is a 100% safe and powerful Android data recovery tool that is widely accepted as the best tool for Samsung users to retrieve deleted or lost files including photos videos.

Check your Google Drive - maybe you have a backup there. Similarly, check Smart Switch for backup. If you use Google Photos App, then check the trash section of the app. If you do not have any backup, anywhere else, then in such condition, you must try third-party data recovery sofwtare.
