Check every feature on your own phone,
in a few taps.
A browser-based diagnostic suite: test your camera, microphone, touch screen, sensors, and battery — no app to install, no technician needed.
Test your phone's hardware
Each test checks one feature and gives you a clear pass or fail. Pick one below, or filter by category to find what you need.
How it works
No accounts, no apps to install. Open a test right on the phone you want to check, and read the result.
Pick a test
Choose the feature you want to check — camera, mic, touch, or sensors.
Allow access
Grant camera, mic, or location permission when prompted — only for that test.
Follow the prompt
Tap, tilt, or speak as instructed so the test can read your device's response.
Get a pass or fail
See an instant result for that feature, right in the tab.
A faster way to know what's actually wrong
No repair shop appointment or paywalled app — just focused tests that answer one question at a time.
Zero setup
Every test loads instantly in a browser tab. Nothing to install or configure.
Privacy-first
Camera, mic, and location access is used only for the test you run, and never leaves your device.
Single-purpose tests
Each test checks one feature well, so you get a clear answer fast.
Uses real hardware
Tests talk directly to your browser's camera, mic, and sensor APIs — not a simulation.
Actually free
No tiers, trials, or feature walls. The full test suite is free to use.
Works on any phone
Any modern mobile browser — no app store, no account, no platform lock-in.
Where these tests fit into your day
Common moments where a quick check saves you money or hassle later.
Before you hand over cash

Did anything break?
Check the camera, speaker, and touch screen after a screen or battery swap.
Document the fault
Get a clear pass/fail result to reference when you file a claim.
Check it out of the box
Run through every hardware feature before your return window closes.
Hardware or software?
Isolate whether an issue is a broken part or just a misbehaving app.
