Description

Not sure whether a USB drive will work with your Android phone? USB OTG File Transfer Checker helps you check OTG readiness, understand a connected USB device, and move selected files through Android's secure system file picker.

CHECK BEFORE YOU TRANSFER
• See whether Android reports USB host support
• Detect when a USB device is attached or removed
• View useful device details and connection status
• Follow clear troubleshooting for adapters, power, and file access

OPEN YOUR USB DRIVE SAFELY
Choose the USB drive or folder through Android's Storage Access Framework. You stay in control of exactly which location the app can access.

MOVE THE FILES YOU CHOOSE
• Copy photos, videos, documents, and folders
• Transfer from phone to USB or USB to phone
• Review duplicate-name conflicts before replacing a file
• Pause or cancel a supported transfer
• See a completion summary with file count and total size

CLEAR CONNECTION GUIDANCE
The readiness screen separates three different questions: Does the phone support USB host mode? Is a device currently attached? Has Android granted access to its files? That makes common OTG problems easier to diagnose.

NO ROOT REQUIRED
Core checking and system-mediated file access do not require rooting your phone.

PRIVATE, USER-CONTROLLED ACCESS
The app uses Android's system picker so you choose the files and folders it can access. No account is required for the core checking and transfer flow.

COMPATIBILITY NOTE
USB behavior depends on the phone, adapter, drive power needs, Android version, device software, and file system. Android may mount some drives but not others. The app cannot enable missing OTG hardware or guarantee support for every FAT32, exFAT, or NTFS device.

Android controls USB mounting and removal. When available, the app provides safe-removal guidance; it does not claim to unmount every drive itself.

Connect, check, choose a folder, and move your files with a transfer flow that explains what is happening.

Initial release with USB OTG compatibility checks and guided file transfer tools.
