Used USB Data Recovery: Lost Files for Android?
Editors’ Review
Experience USB Data Recovery: Lost Files, developed by Stephen Kingston, a mobile utility that recovers deleted data from external USB storage on Android devices. The app uses its own USB stack and filesystem engines to read drives the operating system may not mount, offering Quick Scan for original names and Deep Scan to rebuild files from raw sectors. It supports major filesystems and encrypted volumes, includes file previews, and targets Android users with OTG-capable devices who want on-device recovery without root.
What does the app do on Android devices?
The app reads external storage through its own USB stack and filesystem engines so a mobile device can access drives the OS might refuse. It supports NTFS, exFAT, FAT32, APFS and HFS+ and recovers photos, videos, documents and audio from USB flash drives, camera cards and external hard disks. Quick Scan restores files with original names and folders while Deep Scan rebuilds files from raw data when directory structures are missing.
Is it safe to scan encrypted or corrupted drives?
The app enforces a strict read-only guarantee and does not write back to source media during scanning, reducing risk of overwriting recoverable data. It can open BitLocker To Go and FileVault volumes provided the user supplies the password or recovery key. File previewing lets you verify content before export, and Deep Scan attempts sector-level reconstruction on corrupted partitions rather than relying on intact directory entries.
Do I need technical knowledge and what hardware is required?
The app does not require root access because it uses its own USB stack, but you need an Android device with USB OTG support and a USB-C or OTG adapter to connect drives. Scanning and previews are available without unlocking full recovery; the app lets you save a small number of recovered files before requiring an in-app unlock to restore additional items. The developer designs the tool to avoid ads, trackers and telemetry collection.
Pros
- Supports NTFS, exFAT, FAT32, APFS and HFS+ on Android
- Strict read-only mode prevents writes to source drives
- Handles BitLocker and FileVault volumes with provided keys
- Quick Scan restores original file names and folder structure
Cons
- Requires a USB OTG connection and compatible adapter
- Bulk recovery requires an in-app unlock to restore additional files
- Deep Scan results need verification for heavily damaged partitions
Bottom Line
Practical on-device recovery with a clear trade-off
The app is a practical option for Android owners who need to recover files directly from external drives without using a desktop. It excels at accessing complex and encrypted volumes on the device, but relies on a physical OTG connection and an in-app unlock for bulk restores. Plan to connect a powered adapter for larger drives during recovery and use previews to confirm results before exporting.
