USB OTG Checker - Android USB OTG Capabilities Verification Tool
USB OTG Checker is a free tool for Android devices that verifies and checks the USB OTG capabilities of your device's system without rooting your phone or tablet. This app quickly and effectively performs a full check to confirm whether your device can support USB OTG or not. If your device supports USB OTG, then it means that you can connect it to standard USB input devices such as keyboards, external storage, and more.
The app has multiple features that allow you to check your device's USB OTG capabilities. You can check if your device operating system or custom ROM has the USB OTG API, if your device has loaded with USB OTG driver or kernel to communicate with the USB OTG connected device, and if you can access (view) the USB OTG connected external storage folder. Additionally, the app also has a RAM cleaning capability.
