Screen Test & Calibrate

Screen Test & Calibrate is a comprehensive utility tool designed to help you analyze, test, and calibrate your device’s touchscreen and display performance. Whether you want to test a newly purchased phone, verify a screen replacement, or diagnose touch response issues, this app provides detailed diagnostics.

Key Features:

* Multi-touch Tester: Check how many simultaneous touch points your screen supports. View touch coordinates in real-time, display grid lines, outer rings, and monitor screen density (DPI).

* Screen Grid Test: Fill a complete grid of touch points to verify that every area of your screen is responsive and fully functional.

* Dead Pixel Test: Detect stuck or dead pixels on your display. Cycle through solid colors (Red, Green, Blue, White, Black, and custom colors) manually or automatically at set intervals.

* Touchscreen Repair & Calibration: Calibrate and optimize your touchscreen response times. Analyze touch latency across multiple areas and apply software calibration to reduce response lag.

* Display Calibration: Adjust color balance, contrast, and brightness to enhance your screen’s visual output.

* Gesture Calibration: Calibrate basic touch gestures, including single taps, double taps, dragging, swiping, and pinch-to-zoom.
