Android Auto Not Working After Update How to Fix Connection and Function Issues

If Android Auto stops working right after an update, it usually means the app or your phone’s system can’t connect properly to your car anymore. This often happens because of new bugs, corrupted app data, or settings that changed during the update. Fixing it typically involves restarting devices, checking your USB connection, clearing app data, and making sure your phone and car software are up to date.

What does it mean when Android Auto stops working after an update?

When Android Auto fails after an update, common symptoms include your phone not connecting to the car at all, a blank or frozen Android Auto screen on your vehicle’s display, or the app crashing right after launch. Voice commands may stop responding, or the connection might drop unexpectedly. Sometimes, apps like Google Maps or Music won’t open through the Android Auto system.

Why does updating Android Auto or your phone sometimes cause problems?

Updates can introduce bugs or compatibility issues between your phone’s Android version, the Android Auto app, and your car’s infotainment system. App data or cache might get corrupted during the update, which causes unexpected behavior. Also, the update might reset or disable important permissions and settings needed for Android Auto to work. Additionally, your car’s system might not support the newest Android Auto version yet, leading to connection failures.

How can I fix Android Auto if it’s not working after the update?

Follow these steps to troubleshoot Android Auto after an update:

1. Restart your phone and your car’s infotainment system to clear temporary issues.
2. Check your USB cable and ports. Use a high-quality, data-capable cable and try different USB ports in your car.
3. Clear the cache and data for Android Auto:

Settings > Apps > Android Auto > Storage > Clear Cache
Settings > Apps > Android Auto > Storage > Clear Data

4. If clearing data doesn’t fix the problem, uninstall and reinstall Android Auto from the Play Store.
5. Reset app preferences to restore any disabled permissions or default apps:

Settings > Apps > Menu (three dots) > Reset app preferences

6. Make sure Bluetooth and location services are enabled on your phone, as Android Auto relies on them.
7. Disable battery optimization for Android Auto to prevent the app from being blocked:

Settings > Apps > Android Auto > App battery usage > Unrestricted

8. Verify your phone’s USB connection mode is set to file transfer, not just charging:

Settings > Connected devices > USB > File Transfer

These steps resolve most issues caused by updates.

How do I verify that Android Auto is working again?

After troubleshooting, connect your phone to your car’s USB port. The Android Auto interface should appear on your car’s screen within seconds. Open apps like Google Maps or your music app through Android Auto. Test voice commands by pressing the voice button and saying something simple like “Navigate home” or “Play music.” If these work smoothly without errors or disconnections, Android Auto is working properly.

Could my car’s infotainment system need updating too?

Yes. Your car’s infotainment system firmware may need an update to stay compatible with the latest Android Auto versions. Check your vehicle manufacturer’s website or user manual for instructions on updating the system. Some updates are done via USB drives or at the dealer. Without the latest firmware, even a fully updated phone might fail to connect correctly.

What settings or permissions should I check on my phone for Android Auto?

After an update, some settings can reset and block Android Auto:

• Permissions: Confirm Android Auto has permission for location, microphone, and phone.

Settings > Apps > Android Auto > Permissions

• Battery optimization: Exclude Android Auto from battery saver restrictions.
• Default apps: If applicable, ensure Android Auto is set as the default app for car connection.
• USB preferences: Set your phone’s USB mode to file transfer instead of charging only.

Double-check these settings to avoid inadvertent blocks.

How can I prevent Android Auto from breaking after future updates?

To reduce problems after future updates:

• Read update notes before installing to spot known issues.
• Avoid beta or developer preview versions of Android or Android Auto unless necessary.
• Keep your car’s infotainment system firmware updated regularly.
• Use high-quality USB cables and maintain good connections.
• After updates, check permissions and settings haven’t changed before relying on Android Auto while driving.

Conclusion

If Android Auto stops working after an update, first restart your phone and car system and check your USB cable. Clearing app data or reinstalling Android Auto often fixes corrupted files. Also check your phone’s permissions and battery settings, and update your car’s firmware if possible. These steps should restore Android Auto so you can get back on the road quickly.
