Display Touch Tester

Display Touch Tester is a easy, no-nonsense toolkit for checking the health and quality of any Android screen. Whether you're buying a new phone, inspecting a used device, calibrating a display, or just curious about your panel, it gives you everything you need in one clean, ad-free app.

Run professional-grade screen tests in seconds and see exactly how your display performs — dead pixels, stuck pixels, color uniformity, touch accuracy, refresh rate, and screen burn-in.

▓ WHAT YOU CAN TEST

● Dead Pixel & Color Uniformity Test

Fill your screen with pure red, green, blue, white, black, and custom colors to spot dead pixels, stuck pixels, dust, and backlight bleed. Tap to cycle colors, long-press to enter any custom hex color, and swipe down to exit.

● Gradient & Banding Test

Smooth color ramps and a stepped reference chart reveal color banding, tint issues, and gradient smoothness — perfect for checking panel quality and color depth.

● Multi-Touch Visualizer

Test your touchscreen digitizer with up to 10 simultaneous touch points. Every finger is shown with a glowing ring, crosshair, and live coordinates so you can confirm touch accuracy and detect unresponsive areas.

● Refresh Rate Tracker

Measure your screen's real-time refresh rate (FPS) and see every display mode your device supports — ideal for verifying 60Hz, 90Hz, 120Hz, or higher panels.

● Burn-In Fixer & Prevention

Exercise stuck pixels and reduce screen burn-in on OLED/AMOLED displays with noise, scrolling bars, and color-flash patterns, plus a session timer.
