Samsung A11 Is Connected by USB but Recovery Apps Cannot See Its Storage
TL;DR:
Desktop recovery apps like PhotoRec and Recuva cannot retrieve deleted files from a Samsung Galaxy A11's internal storage because Android uses a file-transfer protocol rather than allowing raw disk access to its encrypted flash memory.
● Changing the USB connection to File Transfer mode, installing different Windows scanners, or rooting the device will not make the internal storage readable as an ordinary disk.
● Recovery efforts must focus on locating existing copies in app Trash folders, Google Photos, Google Drive, Samsung Cloud/OneDrive, messenger exports, or computer backups.
● Files stored on a removable microSD card are exempt from this internal encryption limit and can be scanned by desktop software if the card is removed and read directly.

Samsung A11 Is Connected by USB but Recovery Apps Cannot See Its Storage
USB File Transfer on a Samsung phone is not the same as exposing an HDD or SD card as a raw disk. That is why desktop tools can see ordinary USB drives but cannot select a Galaxy A11's internal storage for deleted-file scanning.
In this r/datarecovery Samsung A11 case, the owner had accidentally deleted important files. PhotoRec and Recuva worked on flash drives in the past, but neither listed the phone even after switching USB to File Transfer.
Why the Phone Is Missing From the Disk List
Android normally exposes shared files through a file-transfer protocol rather than unrestricted raw access to encrypted internal flash. The Android Open Source Project documents file-based encryption used on modern Android devices; storage cleanup imposes further limits on retrieving deleted internal-file data.
Changing USB modes, installing another Windows scanner, or repeatedly rooting or resetting the phone will not make the internal deleted bytes available as an ordinary disk. Do not factory reset the phone while checking for other copies.
Look for Copies Outside the Deleted Internal Data
Check the app's Recently Deleted or Trash location, Google Photos, Google Drive, Samsung Cloud/OneDrive where applicable, messenger exports, and any previous device or computer backups. A removable microSD card, if the missing files were actually stored there, is a separate recovery case and can be evaluated outside the phone when it is readable.
If the only copy was deleted from encrypted internal storage, set expectations realistically: consumer desktop recovery software cannot promise to restore it. Spend effort locating backups rather than running endless USB scans.
