How to use OTG function on mobile phone?

OTG can be used in the following ways:

1, mobile phone charging: mobile phone A is plugged into OTG cable, and the other end is connected to mobile phone B through data cable. A can charge B (mobile phone A is required to support OTG).

2. Connect the mouse and keyboard: When connecting, the mobile phone needs to provide power for the mouse or keyboard, and some devices may not work normally due to high power requirements. If you encounter this problem, try replacing the mouse or keyboard.

3. File transfer: Connect the mobile phone to the USB storage device through the OTG line, then enter the "Local" tab of "File Management" and select "USB" to transfer files between the mobile phone and USB storage device.
