Evidence is labeled by what it actually means
A browser can expose useful signals, but it cannot certify an entire device. TestingPhone keeps automated observations separate from human judgment.
Read the complete result guide- Browser-observed
- The browser reports an event or capability it directly exposed, such as simultaneous touch contacts.
- User-confirmed
- You report what you saw, heard, or experienced when a browser cannot judge physical quality.
- Manual check
- The inspection provides a structured physical step that remains entirely under your control.
- Unsupported
- The browser or connection cannot safely expose the required capability, without implying hardware failure.
Trust and privacy
Useful inspection without unnecessary collection
No account is required. Results stay in this browser on this device, and camera or microphone permission is requested only when you start a test that needs it.
TestingPhone provides a functional inspection—not manufacturer certification, a warranty, or a guarantee against hidden or intermittent defects.
