To turn on Classic Invert (color inversion) on an Android phone, follow these steps:

1. Open the Settings app on your Android device.
2. Scroll down and tap Accessibility.
3. Tap Visibility enhancements , Display , or Color and motion (the exact name may vary depending on your Android version).
4. Find and tap Color inversion.
5. Toggle the switch next to Color inversion to enable it.

This will invert all colors on your screen, turning white backgrounds to black and inverting all other colors, including images and videos

. Additionally, you can enable a shortcut for easier access:

• In the Color inversion settings, toggle on the Color inversion shortcut.
• This adds a floating button on the edge of your screen that you can tap anytime to quickly toggle Classic Invert on or off

Classic Invert differs from Dark Mode in that it inverts all colors on the screen rather than selectively changing backgrounds while preserving other colors

. This method works on most Android phones, including Android 13 and various manufacturer versions, though menu names may slightly differ
