Camera, Touch & Sensors — Tests & Tools

Test the touchscreen of a phone, tablet, or touch laptop for dead zones. Slide a finger across a full-screen grid — every square you touch lights up, and any that stay dark map exactly where the screen is not responding.

Test how many simultaneous touch points your phone or tablet screen can track. Each finger gets a numbered circle, with live and peak counters — most modern screens track 10.

Test the gyroscope of a phone or tablet in the browser. Rotate the device and watch the live alpha, beta, and gamma readings — each axis is checked off once the sensor clearly responds, so a dead or drifting sensor shows up in seconds.

Test your webcam in the browser — a live preview with the camera's real resolution, frame rate, megapixels, and brightness, plus a snapshot to check framing. Nothing is recorded or uploaded.

Test the accelerometer of a phone or tablet in the browser. Live X, Y and Z readings in m/s², a g-force meter, and a shake counter show whether the motion sensor responds on every axis.

Test the vibration motor of an Android phone or tablet in the browser. Trigger a single buzz, play patterns like pulse, heartbeat, and SOS, or build a custom rhythm — if the phone buzzes along, the motor works.
