What is Android Auto Communication Error 12?

It’s a very simple problem. You know that it’s a problem with the USB cable, so changing the cable should solve the problem. But, in reality, it’s confusing. You got to choose the right cable! Even though you have established a good connection one day, the next, you could encounter the same error. Even the stock USB cable that comes with your smartphone – that you know will work just fine — won’t give you a guarantee that it will also work.

Blame the USB cable. But, how do you know if the USB cable you’ll use will work or not?

USB cables are just made of four hairline wires running inside. If you don’t store the cables properly, it’ll easily get damaged with just minimal stress and strain. With the even thinner USB-C with around 24 tiny wires running inside, you need to always store them properly when not in use. Just one faulty wire could cause this problem if you connect Android Auto. Try using Google’s recommended USB cables so you can assure that it will work.

Is There a Way to Get Rid of It?

In this regard, you can easily go to Google Play Store>Menu (hamburger)>My Apps & Games>Android Auto. You can immediately see the Update button next to the app. Tap the Update button to get the latest version.

Alternatively, instead of tapping the Update button directly, you can tap the app, then tap the three vertical dots in the upper-right corner. Now, you can see the Enable auto-update with a checkmark box right next to it. If it’s set to auto-update, it has a green box, while white or gray with no checkmark if it’s disabled. Simply tap the box to enable auto-update.

Close All Running Programs Before Opening Android Auto.

So, before you connect the USB cable to your car, try killing all running apps. Likewise, you can do a quick restart to ensure that no apps are competing with Android Auto.

First, ensure that the cable is less than 6 ft long without any cable extensions or adaptors. Second, you must choose a USB cable with a USB icon. If it’s still hard to find which works best, check out recommended cables. For micro USB try the one from Anker, AmazonBasics, or Monoprice. If you need Type C, you can try the USB cables from Inatech or Choetech.

The Final Say

Connecting your smartphone to your car is amazing. Especially with Android Auto, you can do different tasks safely using voice commands. All you need to do is download the latest Android Auto app on your smartphone and connect it to your car via a reliable USB cable.

What do you need to do? Change the cable. Yet, this is not just any replacement. You need to stick to certain requirements — shorter USB cable under 6ft. And, to get rid of the guesswork, use the recommended USB cables for Android Auto. Store your USB cables properly and securely to avoid bumping into this problem again.
