There are two kinds of Android interfaces. One is a Micro USB interface, and the other is a Type-C interface. The common Micro USB interface, which was widely used by most mobile phone models before, is characterized by not being able to plug forward and backward, and the interface is trapezoidal; Type-C interface, which is used on mobile phones, features that the plane interface can be inserted forward and backward, and is widely used in mobile phones and light notebooks at present. Compared with Micro USB interface, Type-C interface has more advantages in interface function, transmission rate and ease of use.
