Android Auto Restart Problem

Android Auto may restart due to various factors. Here's a breakdown of common causes and solutions:

 1. **Software Glitches or Bugs

   - **Outdated Apps/OS**: Incompatibility between the Android Auto app, phone OS, or car firmware.

     - **Fix**: Update the Android Auto app, Google Play Services, phone OS, and car infotainment firmware.

   - **App Crashes**: Corrupted cache/data in Android Auto.

     - **Fix**: Clear Android Auto cache/data via **Settings > Apps > Android Auto > Storage**.

2. **Unstable USB Connection**

   - **Faulty Cable/Port**: Loose, damaged, or low-quality USB cables or dirty ports.

     - **Fix**: Use a high-quality USB cable, clean the ports, or try a different USB port in the car.

   - **Connection Interruptions**: Phone disconnects mid-use.

     - **Fix**: Disable battery optimization for Android Auto (**Settings > Apps > Battery > Unrestricted**).

3. **Overheating**

   - **Phone/Car Environment**: Excessive heat from charging, GPS, or sunlight.

     - **Fix**: Ventilate the phone, avoid direct sunlight, or reduce resource-heavy tasks.

4. **Power-Saving Modes**

   - **Battery Restrictions**: Aggressive power-saving settings limit background processes.

     - **Fix**: Exempt Android Auto from battery optimization and disable power-saving mode.

### 5. **Bluetooth Conflicts**

   - **Pairing Issues**: Bluetooth and USB connections overlapping.

     - **Fix**: Reset Bluetooth connections (unpair/re-pair devices) or toggle Bluetooth off during USB use.

### 6. **Third-Party App Interference**

   - **Conflicting Apps**: Overlays, VPNs, or cleaner tools disrupting Android Auto.

     - **Fix**: Boot phone in **Safe Mode** to test; uninstall problematic apps.

### 7. **Car Head Unit Compatibility**

   - **Outdated Infotainment System**: Older car firmware struggles with newer Android Auto versions.

     - **Fix**: Check for car manufacturer firmware updates.

### 8. **Hardware Issues**

   - **Phone/Car USB Hardware**: Damaged phone USB port or car hardware.

     - **Fix**: Test with another phone/cable; consult a technician if issues persist.

### 9. **Google Server Issues**

   - **Temporary Outages**: Rare server-side problems with Google services.

     - **Fix**: Wait for Google to resolve; check forums like [Downdetector](https://downdetector.com/).

### Step-by-Step Troubleshooting:
