Terms & Disclaimer
The simple rules for using ProDeviceTest, and what to know before you trust a result.
Last updated:
Results are a guide, not a guarantee
The tests run in your browser, so a result depends on your device, your browser and your settings. Passing a test doesn't prove a device is fault-free, and failing one doesn't prove it is broken. For a warranty claim or a repair, rely on the manufacturer's own diagnostics.
Not medical advice
The hearing and frequency tests are not a medical examination and cannot diagnose hearing loss. If you notice changes in your hearing, ringing in the ears or pain, see a doctor or an audiologist.
Volume and screen safety
Start any sound at a low volume and raise it slowly, because loud or high tones can hurt your ears and your speakers. Some screen tests (such as the stuck pixel fixer and the refresh rate test) show flashing colours or fast-moving patterns. Don't use them if you are sensitive to flashing lights, and stop right away if you feel unwell.
Repair tools: use at your own risk
The speaker cleaner / water eject and the stuck pixel fixer use common methods that sometimes work, but they can't promise a repair, and we are not responsible for damage to your device. Let the device dry, and don't charge it while it is wet.
