What if the Android phone driver installed on the computer shows no signature?
Why is there no signature? Could there be something wrong with the downloaded driver? Install pea pods on the computer. Enter the phone settings, turn on usb debugging, and then connect the computer. Pea pods will automatically download and install the driver. If pea pods is connected, the driver has been installed. Or directly install the driver, Baidu search, for example, my model is Samsung N7 100, Baidu search: N7 100usb driver. Download and install it when you find it.
