# MyPhoneSpeaker documentation

Technical reference for the free browser tools on this site. These pages state exactly what each tool plays, records and stores. For step-by-step help with a wet or muffled phone, use the guides.

By Marcus Brown, phone technician

## Tools at a glance

Every tool runs in the browser. No tool needs an account or an app.

| Tool | What it does | Permission | Stored on your device |
| --- | --- | --- | --- |
| [Water eject tone](https://myphonespeaker.com/) | A guided three-cycle tone that pushes droplets out of the speaker grille. | None. Sound starts only after you tap Start. | Drying timer start time and alerts; cue setting; whether you closed the install hint |
| [Speaker and earpiece check](https://myphonespeaker.com/speaker-check/) | Sweep, left and right test, earpiece test and vibration test. | None. Vibration only where the browser supports it. | Nothing |
| [Microphone test](https://myphonespeaker.com/mic-test/) | Record a short clip and play it back to hear if the microphone is muffled. | Microphone, asked by the browser when you tap Record | Nothing. The clip stays in memory and is deleted when you leave. |
| [Speaker problem finder](https://myphonespeaker.com/speaker-problem-finder/) | Answer a few questions and get the most likely fix. | None | Nothing |
| [Wet phone checklist](https://myphonespeaker.com/wet-phone-checklist/) | Tick off each recovery step and track the drying time before charging. | None | Ticked steps; drying timer start time |
