Mobile Device Tests

Mobile Device Tests on DeviceHub cover the full browser suite for phones and tablets: Touchscreen Test and Multi Touch Test for taps and simultaneous contacts; Accelerometer, Gyroscope, and Orientation tests for motion and tilt; Compass and Magnetometer for heading and magnetic field signals; GPS Test for geolocation fixes; and NFC Support Checker for Web NFC (NDEFReader). Older ambient-light and proximity URLs redirect here. Typed permissions stay none across the suite, GPS still explains the browser geolocation prompt because geolocation is outside PermissionKind, and iOS motion tools explain user-gesture plus DeviceOrientation/DeviceMotion permission without inventing union members.

Start with Touchscreen Test, Multi Touch Test, GPS Test, or Accelerometer Test for everyday triage, then drill into Gyroscope, Compass, Magnetometer, Orientation, or NFC when a symptom needs a sharper lens. Results stay honest: many sensors are mobile-only with desktop unsupported; Generic Sensor APIs are mostly Chromium plus secure context and Permissions-Policy; compass absolute heading is approximate; Web NFC is Chromium Android primarily, not iOS Safari; GPS coordinates appear on screen only and are not uploaded by DeviceHub.

FAQ

Mobile Device Tests FAQ

Common questions about this category of diagnostics.

Do sensor tests work on desktop?
Many sensor APIs are mobile-oriented. Desktop browsers often report unsupported; that result is still useful for capability checks, not a DeviceHub defect.
Why does iOS need a tap before motion numbers appear?
iOS requires a user gesture plus DeviceOrientation/DeviceMotion permission before orientation and motion samples flow. Use the on-page enable control, allow the prompt, then move the device.
Does GPS Test upload my coordinates?
No. Coordinates are shown on screen for the diagnostic and are not uploaded by DeviceHub for advertising. Typed permissions remain none, but the browser can still show a geolocation permission prompt, deny anytime and revoke in site settings.
Does Web NFC work in iPhone Safari?
No. Web NFC (NDEFReader) is primarily Chromium on Android. iOS Safari unsupported is expected platform behavior, use Android Chrome or Edge for support checks.
Where did Ambient Light and Proximity tests go?
Those pages were retired because the web APIs are effectively unavailable. This Mobile Device Tests hub is the replacement landing page, with Compass, Magnetometer, and Orientation as practical alternatives.
