OTG is a USB transmission technology, and no additional settings are required. Through OTG jumper, the mobile phone can directly access files in devices such as USB flash drive or digital camera, and can also be connected to external devices such as keyboard and mouse. OTG can be used in the following ways:
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 needs to support OTG).
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.
Transfer files: Connect the mobile phone to the USB storage device through the OTG line, then enter the classified tab of file management and select "USB" to transfer files between the mobile phone and the USB storage device.
