Q：Why can't the earphone and charging port of a 2-in-1 OTG cable be used at the same time?
A：Cause: The keyboard, mouse, headphones, and charging port use the same channel (I/O interface), which will cause conflicts when used simultaneously. Solution: To use functions such as listening to music and charging at the same time, it is recommended to use Bluetooth headphones (it is not recommended to use the phone while charging).
