Turn your phone screen into a full-screen color light, or run a visual screen test to check for dead pixels, stuck pixels, possible screen burn-in, ghosting and uneven display colors.

It is useful for testing new phones, inspecting used phones, checking repaired screens, creating photography or video lighting, and producing relaxing ambient colors.

COMMON USES

• RGB screen light and full-screen color lamp
• Screen flashlight without using the camera flash
• Pixel check and dead pixel test
• Stuck pixel and screen uniformity inspection
• Possible screen burn-in or ghosting inspection
• LCD and OLED display testing
• Photography and video fill lighting
• Room, mood and ambient lighting
• Visibility and signaling in dark environments
• Automatic relaxing color rotation

FULL-SCREEN RGB COLOR LIGHT

Display your selected color across the entire screen.

Adjust the shade smoothly from black through the selected color to white. Use the screen as an RGB light, color lamp, ambient light, photography light or screen flashlight.

RGB COLOR WHEEL CONTROL

Choose colors precisely using the hue wheel and shade slider.

Quickly create red, green, blue, white or custom full-screen colors for lighting and display inspection.

AUTO COLOR ROTATION

Automatically rotate through colors clockwise or anticlockwise.

Use automatic color changing for ambient lighting, mood lighting or relaxing background colors. Stop the rotation at any time with a tap.

STROBE SCREEN LIGHT

Create a screen-based strobe light effect with adjustable speed.

The effect uses the display only and does not activate the hardware flashlight. The strobe rate is limited for safety, and first-time use requires confirmation.

PIXEL CHECK AND SCREEN TEST

Run a full-screen pixel test using solid display colors in this order:

Red → Green → Blue → Grey → White → Black

These test colors can help you visually inspect the screen for:

• Dead pixels
• Stuck pixels
• Bright or dark pixel spots
• Uneven screen colors
• Display discoloration
• Possible screen burn-in or ghosting
• Other visible display problems

The pixel check is useful when:

• Testing a new phone
• Inspecting a used phone before buying
• Checking a screen after repair
• Testing an LCD or OLED display
• Looking for visible pixel or color problems

The dead pixel test is a visual inspection tool only. It does not fix pixels, repair the screen or make hardware changes.

LOCK MODE

Lock the full-screen controls to prevent accidental touches while using the RGB screen light, color lamp, screen flashlight or pixel test.

SAFETY NOTICE

Avoid strobe mode if you are sensitive to flashing lights or have photosensitive epilepsy.

Stop using strobe mode immediately if you experience discomfort.

This app displays colors on the screen only. It does not provide medical, emergency or hardware repair functions.

PRIVACY

The app does not ask for personal information such as your name, email address, phone number or contacts.

Firebase Crashlytics is used for crash and stability diagnostics. See the app’s privacy policy for complete information about data handling.
