Screen Tester is the ultimate local diagnostic utility designed to help you verify the health and functionality of your device's display. Whether you are buying a used phone, checking your device after a drop, or suspecting a display fault, Screen Tester provides the necessary tools to inspect your screen thoroughly and easily.
Key Features:
Pixel Color Test Identify dead, stuck, or faded pixels effortlessly. The app cycles through pure, high-contrast primary colors (Red, Green, Blue, White, and Yellow) at maximum screen brightness. This allows you to spot any pixel irregularities, LCD bleeding, or OLED burn-in with complete visual clarity. Simply tap the screen to switch between test colors.
Touch Digitizer Grid Test Ensure that every part of your touch screen is responsive. The Grid Test overlays a matrix on your screen. By swiping and dragging your finger across the display to fill the grid, you can quickly identify dead zones or ghost touch issues where the digitizer may be failing.
