About this app
**Screen Checker** is an essential utility app that allows anyone to easily and precisely diagnose the condition of smartphone and tablet displays (OLED, LCD). Complete all tests with a single app, whether you are inspecting a device before trading a used phone or want to check the screen condition of your device in detail.
📌 **Main Features** 📌
✔️ **Dead Pixel & Burn-in Test**
Visually check for hidden dead pixels or physical defects on the display through full-screen solid colors (RGB, White, Black, etc.).
✔️ **Touch Screen Test**
Perfectly inspect for dead zones or areas with poor touch recognition by swiping directly over square tiles that fill the entire screen. ✔️ **Gradient & Contrast Test**
Displays smooth gradient screens in four directions (top, bottom, left, and right) to thoroughly check for color banding (staircase effect) and shadow details (black crush) in contrast expression.
✔️ **OLED Pattern Test**
Utilizing precision grid and dot patterns—which are much more advantageous for identifying display distortion than standard solid-color screens—definitively detect burn-in marks, a chronic issue with OLED displays.
✔️ **Text Readability Test**
Fills the screen with ultra-small text that shrinks finely from 24sp to 4sp to examine pixel matching and text rendering clarity, which are characteristic of high-resolution panels such as QHD.
