Frequently Asked Questions
Does this test provide a definitive hardware diagnosis?
No. The test measures signals the browser can safely access and clearly explains its technical limits.
Why can results change between runs?
Background applications, power mode, network conditions, permissions, and operating-system timing can affect results.
How should I repeat the test if I see a problem?
Repeat it on the same device and browser while changing only one condition, so the source of the difference is easier to identify.
