Q：How to use OTG
A：1. Device Charging: Connect device A to the OTG cable, and the other end to device B via a data cable. Device A can charge device B (device A must support OTG and reverse charging).
2. Connecting Mouse and Keyboard: The device needs to provide power to the mouse or keyboard during connection. Since some external devices have high power requirements, they may not work properly. If you encounter this problem, please try a different mouse or keyboard.
3. File Transfer: Connect the device to the USB storage device via the OTG cable, then access "File Manager" to transfer files between the device and the USB storage device.
