Key Developer Options in Samsung DeX

1. Enable DeX Mode

This option allows you to force-enable DeX mode on your device. It's useful for developers who want to test their apps in a desktop environment even when the device is not connected to a desktop monitor. By enabling this option, you can simulate the DeX experience and ensure your app's compatibility.

2. Force Desktop Mode

The Force Desktop Mode option allows you to override app-specific settings and force an application to run in DeX mode. This can be particularly useful for testing apps that might not automatically switch to DeX mode or if you want to see how your app performs in a desktop-like environment.

3. Enable USB Debugging

USB Debugging is an essential tool for developers, allowing them to connect their device to a computer and use development tools such as Android Studio. Enabling this option in DeX mode ensures that you can still debug your apps while using the desktop interface.

4. Show Touches

The Show Touches option displays visual indicators on the screen whenever you touch the device. This can be helpful for debugging touch interactions and ensuring that your app's UI elements are responsive and properly aligned.

5. Show Layout Boundaries

This option highlights the boundaries of various UI elements on your app. It helps developers see how their app's layout behaves on different screen sizes and resolutions, which is crucial for optimizing the app's appearance on a larger display.

6. Window Animation Scale

The Window Animation Scale setting allows you to adjust the speed of window animations. By reducing or disabling animations, you can speed up your testing process and better evaluate your app's performance in DeX mode.
