About this app

USB OTG Checker instantly checks OTG support, manages files on external storage, previews media, and runs an OTG speed test—all in one utility and without root. Our easy OTG checker combines USB compatibility checking and a USB OTG Explorer (OTG view).

USB OTG Checker:
Use the USB OTG Checker to verify USB host support and check OTG support before buying keyboards, mice, cameras, game controllers, hubs, or flash drives. Get quick signals to confirm whether the device can connect and interact with common USB accessories.

USB OTG File Manager and OTG Viewer:
USB OTG File Viewer lets you easily browse, open, and manage files directly from connected USB storage devices such as flash drives, hard drives, and card readers.

OTG Speed Test:
Run an OTG speed test to measure the read and write performance of your USB devices.

Real-Time Device Monitoring:
Get live detection for connected USB devices, with specifications and instant connect/disconnect notifications to assist with troubleshooting and setup.

Device Information:
View model, manufacturer, Android version, screen resolution, battery level, and relevant hardware details.

Key Features:
• Easy OTG Checker for fast compatibility checks
• USB OTG File Manager with full file operations
• OTG Speed Test for read/write benchmarking
• Real-time USB device monitoring and notifications
• Device information display for troubleshooting
Supports FAT32, exFAT, and NTFS (device support may vary).

Important Limitations:
This app tests and reports existing capabilities; it cannot enable OTG on incompatible devices.

Supported Accessories:
Our Easy OTG Checker works with USB storage drives, keyboards, mice, cameras, card readers, game controllers, and hubs that operate under Android USB host mode. Performance and feature availability can vary by device and accessory.

This app sucks the donkeys nuts, one star is an exaggerating lie, zero would be too high. It literally tells you what you already know, the way they make it sound when you read their "synopsis" if you will, it'll tell you the problems you might have with the OTG capability you already know you have...as well as a couple of other things you'll find if you pay any tiny amount of attention to your phone...and don't get me started on the so called "advanced" features.......it's bad enough they make
