Partial Touch Screen Blocker

🧩 Comprehensive Touch & Screen Diagnostic Tool. This app helps identify unresponsive touch zones, dead pixels, and display irregularities on Android devices — so you can quickly check screen health before issues worsen. Importantly, it does not block touches; it only detects blocked or damaged regions for diagnostic use, ideal for users, technicians, or buyers inspecting second-hand devices.

Key features include touch tests (Single Tap, Double Tap, Long Press, Swipe, Pinch) with visual highlights of faulty areas; pixel and display analysis (Auto Dead Pixel test, Manual Pixel Check, Screen Color Test); additional tools (Hand Writing Test, Fading Line Test, Orientation Test); and detailed device/screen information (model, Android version, resolution, DPI, refresh, brightness, sensors). The app runs offline on-device, preserving privacy and avoiding intrusive ads.
