TestMu AI’s **Dark Mode** feature allows you to manually toggle between light and dark themes on **real iOS and Android devices** during manual testing sessions.

This enables testers to validate UI appearance, color contrast, and theme switching for both mobile apps and web applications without writing automation scripts.

## Use Cases

- Validate app UI elements render correctly in dark mode.
- Test color contrast and readability in dark themes.
- Verify icon and image visibility on dark backgrounds.
- Ensure theme inheritance across multiple app screens.
- Check browser and web application dark mode behavior.

## Supported Devices

| Device Type              | Supported OS Version    |
|--------------------------|-------------------------|
| iPhone / iPad            | iOS 13 and above       |
| Android Phones/Tablets    | Android 11 and above    |

## Steps to enable Dark Mode in Manual Testing

**Step 1:** Start a manual testing session on a real iOS or Android device in **App Live** or **Browser Live**.

**Step 2:** Go to the **Device Control tab** and turn the toggle **On** for Dark Mode.

tip

- Dark mode changes are applied at the **system/browser level** and may require refreshing the page for full effect.
- Some legacy websites may not fully support dark mode.
