how to recover “On My Iphone” folder

To recover a deleted "On My iPhone" folder or its contents, you'll need to check the "Recently Deleted" folder within the relevant app, like Files or Photos. If the folder or files aren't there, you'll need to restore from a backup

Check the Recently Deleted folder:

• Files app: Open the Files app, tap Browse, then select Recently Deleted. 
• Photos app: Open the Photos app, tap Albums, then select Recently Deleted. 
• Other apps: If you deleted something from another app, check its corresponding "Recently Deleted" or similar folder (e.g., Notes app, Messages app). 

Recover from Recently Deleted:

• Single file: Tap and hold the file, then select Recover. 
• Multiple files: Select the files, then tap Recover. 
• All files: If available, tap Recover Al

If not in Recently Deleted:

• Restore from backup: If the folder or files are not in the Recently Deleted folder, you'll need to restore your iPhone from a backup (iCloud or computer). 
• Note: Restoring from a backup will revert your iPhone to the state it was in when the backup was created, potentially overwriting newer data.
