Hope you have solved your problem since it has been two years. For the one who still has the same problem, here are some steps to help you recover deleted photos and videos from your Samsung Galaxy S21:
Check the Trash or Recently Deleted Folder:
Samsung devices have a built-in feature called the "Trash" or "Recently Deleted" folder in the Gallery app. Deleted photos and videos are often moved to this folder for a specific period before being permanently deleted. To check:

2. Look for a "Trash" or "Recently Deleted" folder within the app.
3. Open the folder, and you may find your deleted photos and videos there.
4. Select the files you want to recover, and tap the "Restore" option.
Use Samsung Cloud:
If you have Samsung Cloud backup enabled, your deleted photos and videos may be recoverable if they were backed up before deletion. Here's how to check:
1. Go to "Settings" on your Samsung Galaxy S21.
2. Scroll down and tap "Accounts and backup."
3. Tap "Samsung Cloud."
4. Select "Restore data" and choose the files you want to restore.
Google Photos:
If you use Google Photos to back up your media, deleted photos and videos may be recoverable from the cloud. Follow these steps:
1. Open the Google Photos app on your device.
2. Tap the three horizontal lines (menu) in the upper-left corner.
3. Select "Trash" from the menu.
4. Find the deleted photos and videos, select them, and tap "Restore."
Use a Data Recovery Software (PC/Mac):

1. Download and install reputable data recovery software like Coolmuster Lab.Fone for Android, MobiKin Doctor for Android, or Dr.fone, etc. on your computer. Connect your Samsung Galaxy S21 to a computer using a USB cable.
2. Follow the software's instructions to scan your device for deleted photos and videos.
3. Once the scan is complete, preview the recovered files and select the ones you want to recover.
4. Click the "Recover" button to save the selected files to your computer.
