What to know

  • Samsung’s November 2024 update has modified the Auto Blocker feature, which could prevent Android Auto from working on Galaxy devices.
  • The issue occurs when “Maximum restrictions” are enabled in Auto Blocker settings, blocking all USB connections except charging.
  • Users can easily fix this by disabling Maximum restrictions in their phone’s security settings.

The latest November 2024 update for Samsung Galaxy smartphones has introduced changes to the Auto Blocker security feature that might disrupt your Android Auto experience. While the update aims to enhance device security, it has created an unexpected hurdle for Android Auto users.

9To5Google reports that the modified Auto Blocker feature now blocks all USB connections except for charging when set to “Maximum restrictions.” This security measure, while well-intentioned, prevents Android Auto from establishing a wired connection with your vehicle’s infotainment system.

Fortunately, there’s a simple solution to this problem. The Auto Blocker feature isn’t enabled by default, and you’ll only face issues if you’ve manually activated the “Maximum restrictions” setting. To restore Android Auto functionality, navigate to Settings > Security and privacy > Auto Blocker > Maximum restrictions and ensure these settings are turned off.

If you prefer to maintain maximum security while using Android Auto, you have the option to use wireless adapters like AAWireless or Motorola MA1. These devices allow you to bypass the USB restriction while keeping your security settings intact.

For those wondering why their Android Auto suddenly stopped working, checking these security settings should be your first troubleshooting step. Remember, you’ll need to enter your PIN if you choose to completely disable Auto Blocker.
