Accessing Brightness Toggle in Kiosk Mode for Android Enterprise Devices

If you are managing Android devices via Microsoft Endpoint Manager (aka Intune) and enrolling them as Corporate-owned dedicated devices through Android Enterprise, you can meet the use case of a Kiosk device. However, when configuring these devices in Kiosk mode with the Microsoft Managed Home Screen, you may encounter challenges, such as accessing and adjusting the screen brightness.

This guide will provide you with the necessary steps to enable the brightness toggle in the quick settings of Kiosk mode on a Vanilla Android device, which does not use a third-party UI, and the standard “settings” menu. Enabling the brightness toggle in the “settings” menu proved to be particularly tricky, but this guide will walk you through the process.

The Challenge

Typically, on an Android device, the brightness can be adjusted via the settings or the navigation bar. When these devices are enrolled and configured in Kiosk mode via Intune, particularly with the Microsoft Managed Home Screen, the option to adjust brightness through the settings might not be accessible.

The Solution

• To regain control over the brightness settings in the quick settings menu of Kiosk mode, you must enable the toggle via an Intune App Configuration, rather than through the Device Configuration.
• If you wish to adjust the brightness through the device’s Settings menu, it is essential to add both the System UI (com.android.systemui) and the Settings (com.android.settings) as Android Enterprise apps via Intune.
• For example, if you are using a Samsung Android device, you will need to add the One UI launcher (com.sec.android.app.launcher) in addition.
• It is important to note that the brightness toggle is a feature of the System UI, not the settings (thanks Android for that).

Step-by-Step Guide

1. 1. Enroll your devices as Corporate-owned dedicated devices via Android Enterprise in Intune. For more information see: Set up Intune enrollment for Android Enterprise dedicated devices – Microsoft Intune | Microsoft Learn
   2. Roll out the devices in Kiosk mode using the Microsoft Managed Home Screen. For more information see: How to setup Microsoft Managed Home Screen in kiosk mode on Dedicated and Fully managed devices – Microsoft Community Hub
   3. When you are setting up the Device Configuration profile for the Kiosk mode, refer to the Microsoft documentation which Android setting has to be enabled via an App Configuration policy: App configuration policies for Managed Home Screen.
      For example: If you want to enable the brightnes slider (via quick settings), you have to activate it via an App Configuration policy.
   4. To now enable the Brightness toggle, enable the setting “show the brightness slider” in the app configuration policy.
   5. To access the brightness toggle via the Setting, you need to add both the System UI (com.android.systemui) and the Settings (com.android.settings) as Android Enterprise apps via Intune.
   6. Once the System UI is added and enrolled correctly, you should be able to access the brightness toggle via the settings.
   7. Test to ensure the brightness toggle functions as expected.

Conclusion

By following the steps mentioned above, you can effectively manage the brightness settings on your Android Enterprise devices configured in Kiosk mode with the Microsoft Managed Home Screen.
