Touch Screen Test

About

TouchScreen Test lets you check if your touchscreen is working properly — right from your browser toolbar, no website needed.
Just click the extension icon, slide your finger across the screen, and instantly see which areas respond and which ones don't. Dead zones show up in red so you know exactly what's wrong and where.

Key features : 

✅ Dead zone detection — Visually maps every unresponsive area on your screen so you know exactly what's failing and where.
✅ Multitouch support — Use multiple fingers at once to verify your device handles 2, 5, or 10-point touch correctly.
✅ Live coverage tracking — A real-time percentage counter shows how much of your screen has responded as you swipe.
✅ Fullscreen mode — Expand the test to cover your entire display, including the edges and corners that are easiest to miss.
✅ Screenshot & share — Capture your results as an image to keep as a record or share with a repair shop.
🔒 Completely private — No accounts, no data collection, no internet requests during the test. Everything runs locally inside your browser.
