Why test first
- Most “broken” devices are not.A muffled phone after rain is usually water in the grille. A dead earbud is often a pairing glitch.
- A verdict, not a percentage.Every test ends with what the result means and what to do next — never a fake success rate.
- Nothing to install.Tests run in your browser. No account, no upload. How we test.
