Android auto 

Android Auto is an application that mirrors your Android phone into your car’s system. It was built by Google to assist you while you are driving. It helps you assist with very well-known Google Assistance. You just have to say “Ok Google” to get several tasks done. At this time more than 400 car models support android auto (Don’t worry, even if your car model doesn’t have it, you can easily add android auto to it) Many cars now come with already installed android auto functionality. The functionality may be available in your car by way of a wired connection or wireless connection. With android auto, you can focus on driving and control your phone at the same time by using the voice command or the car’s touchscreen.

Why does android auto keep disconnecting

The issue of android auto keeps disconnecting can be caused by several reasons, but the reason I have listed below can be the main cause :

  • Battery optimization feature: The battery optimization feature does not let some processes occur (or kill them) to save the phone’s battery. So, the battery optimization feature can be the one causing this issue. Try switching off the battery optimization feature and then try to connect. I have mentioned the process to switch it off step by step in the article below just follow it.
  • Outdated application: By outdated application, I meant your android auto app, google play services, phone’s OS, or the unit’s firmware. Android auto may be disconnecting due to the android auto app, google play services, phone’s OS or the unit’s firmware being outdated. The outdated application can cause incompatibility with others. We suggest you keep them updated.
  • Improper configuration or the developer option: In USB-type connections, improper USB debugging or developer option control can be the major cause of app disconnecting. They control phon’s many settings so, if any of these settings are in a misconfigured state then it will cause android auto connection issues.
  • Mock location: Many of you might not know but there is a mock location feature on our phones. If the mock location feature is on then it might be causing the issue of disconnecting. Try turning off the feature and then try connecting. The steps to turn off the mock location feature are written below in the article.
  • Corrupted installation of the android auto app, corrupt cache, or corrupt data: There might be some issues while installing the android auto application, or a recent update of the app has corrupted the cache and data somehow can be causing the disconnection issue. 

Things you should know before solutions

  • Many users have suggested disabling the “Auto Rotate” feature of your phone when using android auto
  • The problem can be your phone too so, many people have recommended replacing it
  • Several people have suggested uninstalling the troublesome applications on your phone (Example – Spotify)
  • Make sure to check that the android auto app is enabled on the car’s entertainment unit
  • Enabling the “Do not disturb” mode on your phone can help a lot, according to many users
  • Please check the capability of the android auto with your car, highly told to make sure of it (by users)
  • “High-Speed USB 3.1” is the best choice for connecting, when using a USB connection to connect the android auto and car’s head unit
  • People say that make sure to enable the “Data Transfer Mode” when connecting with your car’s entertainment unit  
  • It is recommended to delete all the “Data” and “Settings” from your car’s entertainment unit and establish a new connection to solve the issue
  • Installing “A Wireless Dongle” is recommended by many users, may work and may not 
  • Select the “USB tethering” to fix the issue

Solutions- Now you know the major reasons behind the disconnection issue, besides these issues there may be other issues too, which are causing the disconnection error. Let’s head to the solutions below. 

Try another USB cable or clean the USB ports

Before moving to the tougher solutions first let us try our bare minimum, the disconnection issue may just be solved by cleaning the USB ports or by just changing your USB cable. The reason behind this error can be dirt stuck in the USB ports or the phone’s stock cable. The dirt may be acting as a barrier to the connection. Or it is that your USB cable is not working properly, time to buy a new one (I can’t change my phone right now, the USB cable is dead). Follow the instructions written below to clean the USB ports:

  1. Search for a sharp pointing object such as a needle, toothpick or just fold a paper like it. (I use a needle and highly recommend you all to use it)
  2. Remove dirt from the USB contact pins of the phone or the cable. (Be gentle while cleaning, do not damage them)
  3. Check by reconnecting to ensure that android auto is connecting completely fine
  4. If it did not work try using the phone’s stock cable to connect the phone and check if the problem is now solved or not
  5. If all this did not work for you then try using special cables like a data rate USB 3.1 cable or a special high-speed cable (kind of similar to an Anker cable)
  6. If the problem is now fixed and you only face it during car bumps or some kind of shock then keep the phone on a soft place to absorb the sudden shock (like a cushion or something)

  2. Click on the Restart or reboot option and wait until your smartphone restarts.

Disable Battery optimization
