Settings not functional on current device: Enable Esper Remote Viewer in Android Accessibility

Android

If you see the error "Settings not functional on current device" when trying to start a Remote Control session in the Esper Console, the Esper Remote Viewer accessibility service may be disabled on your Android device. This article explains how to enable it and restore Remote Control functionality.

Before you begin

You'll need physical access to the affected Android device to enable the accessibility service through its settings. If the device is in a locked kiosk mode, you may need to use ADB (Android Debug Bridge) instead.

How to enable Esper Remote Viewer in accessibility settings

1. On the Android device, open the native Settings app.
2. Navigate to Settings → Accessibility.
3. Locate Esper Remote Viewer in the list of accessibility services.
4. Tap Esper Remote Viewer and toggle it to Enabled, or tap Use Service if prompted.
5. Confirm any system permission dialogs that appear.
6. Return to the Esper Console and start a new Remote Control session for the device.

The Remote Control session should now launch successfully without the error.

If the accessibility service is not visible or greyed out

On some devices, the native Settings app may not provide access to the Esper Remote Viewer service due to OEM restrictions or device lockdown policies. In this case, you can grant the permission using ADB:

adb shell settings put secure enabled_accessibility_services com.example.app/com.example.app
adb shell settings put secure accessibility_enabled 1

If the service re-disables immediately after enabling

The accessibility service may be blocked by your device's active Blueprint configuration. Check your Blueprint settings:

1. In the Esper Console, go to Blueprints.
2. Select your active Blueprint.
3. Navigate to Permissions / Accessibility.
4. Ensure Esper Remote Viewer is explicitly allowed or enforced.

For long-term prevention across multiple devices, configure your Blueprint to enforce the Esper Remote Viewer accessibility service rather than relying on manual enablement.
