USB cable of Android Auto

Why the culprit of Android Auto Erro 12 is USB cable?

The cable is not as tough as it may seem. In fact, if the cable was working well yesterday, it is possible that it won’t work today. As the USB cable has 4 hair-thin wore running inside, so one of them gets a small crack is easily possible.  If we look at USB-C it’s even thinner cable, and we have 24 wires running so the chance of 1 wire developing a fault is way higher. Besides this, each device, even the same phone/model have a slightly different tolerance to the wire and wire faults. A change of resistance in a cable with 1 or 2 ohms may not affect one device but make the other one fully un-functional.
