Phone Check
Test your phone or tablet right here in the browser - no app to install. Phone Check runs the checks a browser can honestly answer - touchscreen, a screen / dead-pixel color-field test, motion and environment sensors, both camera lenses (graded for sharpness and exposure), microphone and speaker, vibration, and network - and clearly labels what a browser cannot check, so a used-phone buyer is never misled.
Read the Phone Check guide for what each check means and what a browser can and cannot see.
Privacy: Runs in this browser tab. The camera and microphone previews stay on your device - nothing is recorded or uploaded. Only the Network check makes a small request to
edge.desktest.net (DeskTest.net's own server, which stores nothing) to confirm you can reach the internet and measure round-trip time. No photos, audio, files, or personal data leave this device. View source to verify.A short guided walkthrough. Your browser will ask permission before the camera, microphone, or motion sensors turn on.
