Multi-touch Test

Multi Touch Tester helps you check how your device screen responds to touch input. Use the touch surface to test finger tracking, multi-touch support, edge and corner response, ghost touches, and possible dead zones. The app displays useful real-time information while you test, including active fingers, peak touch count, screen coverage, touch coordinates, movement trails, and ghost touch warnings. Key features: - Test single-touch and multi-touch detection - View active finger count and peak simultaneous touches - Check screen coverage with a visual scan grid - Detect possible dead zones across the screen - Watch for ghost touches, sudden jumps, and unstable input - Use fullscreen mode for better edge and corner testing - Show or hide grid and touch trails - Reset test data anytime - Choose light, dark, or system theme Multi Touch Tester is useful for checking a new phone, diagnosing screen issues, testing after a repair, or confirming whether touch problems are caused by the screen, charger, case, or screen protector. For best results, clean your screen, remove thick cases or protectors if needed, and repeat the test before deciding that an area is faulty.
