Check a phone before you buy

How to use this tool

1. Open this page on the phone you want to check. Clean the display and use normal room lighting.
2. Choose a test, or follow all four in order. Run the sound checks separately if needed.
3. Record what you notice and review the checklist. Ask the seller or a repair professional about anything uncertain.

Understanding your results

The checklist records your observations in this browser tab. It does not automatically grade a phone or prove that every component works.

What an online phone check can help you notice

Before buying a used phone, try the functions you will actually use. Solid screen colors can make visible marks easier to notice; the touch grid shows where the browser receives finger input. Camera preview lets you inspect the cameras made available to the browser, while a short vibration request can help you check the motor on supported phones. Each test explains its limits before you interpret the result.

Keep the purchase checks practical

Also inspect the casing, buttons, charging port and lenses, and try a call with permission. Check account locks, ownership and any warranty with the seller. These pages cannot verify battery health, hidden liquid damage, authenticity, network compatibility, Wi-Fi hardware or Bluetooth hardware. A browser check is one part of an inspection, not a purchase certificate.

Privacy and availability

You do not need an account. Camera access starts only when you ask; the preview is not recorded or uploaded. Your checklist stays in session storage in this tab and can be cleared. Browser support varies, so an unavailable feature should be marked as skipped rather than counted as a failed component.
