À propos de l'application
OLED Checker is a free, lightweight tool designed to help you thoroughly test your OLED and AMOLED display. Whether you just bought a new phone or want to check your current screen's health, OLED Checker gives you everything you need.
TESTS INCLUDED:
- Pure Colors — Full-screen black, white, red, green, and blue to reveal dead pixels, stuck pixels, and uneven
lighting.
- Gray Uniformity — Subtle gray tones (5%, 10%, 15%) to detect burn-in, banding, and screen retention.
- Ghosting Test — Animated checkerboard pattern to identify image ghosting and slow pixel response.
- Touch Test — Interactive grid that maps your entire screen to find dead zones and unresponsive areas.
- Free Draw — Draw freely on screen to spot display defects with your own patterns.
WHY OLED CHECKER?
- Immersive fullscreen — Tests run with no distractions (system bars and ads are hidden during tests).
- Simple and fast — No account needed, no setup required. Open the app and start testing.
- Lightweight — Minimal app size, no unnecessary permissions.
- Ad-supported with optional one-time purchase to remove all ads.
Perfect for checking a used phone before buying, verifying screen repairs, or simply keeping an eye on your display's
condition over time.
