You can test your microphone directly in your browser using Test Your Gadget. Allow microphone access when prompted, then speak into the microphone to check whether your voice is being detected.

Yes, if the microphone test provides playback, you can use it to check whether your recorded voice is being captured correctly and whether the playback sounds clear.

Yes, you can use an online microphone recorder to capture a short recording and play it back to check microphone input quality.

Check whether your browser has permission to access the microphone and make sure the correct microphone is selected in your device or browser settings.

Browsers require permission before a website can access your microphone. This helps prevent websites from accessing the microphone without your approval.

Yes. You can test the microphone input and headphone or speaker output separately to check whether both parts of your headset are working.

Yes. Testing your microphone before using services such as video meetings can help confirm that your microphone is being detected and capturing audio.

You can test your webcam directly from your browser. Allow camera access when requested and check whether the camera produces a live image.

Yes. A browser-based webcam test can check the camera without requiring a separate desktop application, provided your browser supports camera access.

Yes. A combined camera and microphone test can help you check both video input and audio input before a video call.

Open the relevant camera and microphone tests, allow the required browser permissions, and check that both devices are detected and working correctly.

Check whether the browser has camera permission and whether another application is already using the camera. You should also check that the correct camera is selected when multiple cameras are available.

You can run a browser-based webcam and microphone test before joining a meeting to check your camera image and microphone input.

Yes. An online speaker test can play test audio so you can check whether your speakers are producing sound correctly.

Use separate left-channel and right-channel audio tests to determine whether sound is coming from the correct speaker.

Testing the channels separately can help identify reversed stereo channels or a problem with one side of a stereo speaker or headphone setup.

Yes. You can use browser-based audio tests to check headphone output, including separate left and right channel playback.

Yes. In a stereo setup, the left and right channels are intended to play through their corresponding sides. A channel test can help identify incorrect channel routing.

A surround sound test plays audio through different channels to help check whether a multi-channel audio setup is routing sound correctly.

You can use a browser-based left/right speaker test or the operating system's sound settings to check the two stereo channels separately.

Yes. You can use a browser-based stereo audio test on a supported iPhone to check the left and right audio channels.

A keyboard test can display the keys detected by your browser as you press them, helping you identify keys that may not be registering.

Press the key while the keyboard test is open. If the browser detects the key, it should appear as an active or detected key in the test interface.

Yes. A browser-based keyboard test can detect supported keyboard input without requiring additional software.

Yes. Keyboard and mouse tests can be used separately to check common input problems directly from a browser.

A mouse test can detect common mouse inputs such as movement, button presses and scrolling.

Press the left, right or middle mouse buttons while the test is open to check whether the browser detects the corresponding input.

Yes. A mouse test can detect scroll-wheel movement and help confirm that scrolling input is being registered.

Yes. A double-click test can help determine whether two clicks are being registered when you perform a rapid double click.

CPS stands for clicks per second. A CPS test measures how many clicks are registered during a defined period.

Connect the controller to your device and open a browser-based gamepad test. Supported controllers can expose buttons, axes and other inputs to the browser.

Supported Xbox and PlayStation controllers can be tested through browser gamepad APIs when the browser and controller expose the required inputs.

A controller test can display analog stick positions while the stick is released. Unexpected movement away from the neutral position can indicate possible stick drift.

Yes. A compatible gamepad test can display trigger and analog-axis values, which can help you inspect their input range and dead-zone behaviour.

If your browser and controller support the required gamepad vibration features, a controller vibration test can send a vibration command to the device.

A dead pixel test displays solid colours across the screen so you can visually inspect individual pixels for pixels that remain off or behave differently from surrounding pixels.

Yes. A browser-based dead pixel test can display different colours that make visible pixel abnormalities easier to inspect.

Yes. You can use a browser-based screen test on a supported phone to visually inspect the display.

A dead pixel may remain completely inactive, while a stuck pixel may remain fixed on a particular colour or state.

A pixel test can help identify display problems, but it cannot guarantee that a physically defective pixel can be repaired.

A refresh-rate test can use browser rendering behaviour to help determine the display refresh rate under the current device and browser conditions.

A compatible browser-based refresh-rate test can help check the current display behaviour and distinguish between commonly used refresh rates.

Open a touchscreen test on your phone and touch different areas of the display to check whether touch input is being detected across the screen.

Yes. A supported browser can detect multiple simultaneous touch points, allowing you to check multi-touch input.

Move your finger across different areas of the screen while using a touch test. Areas where touch input consistently fails to register may indicate a possible dead zone.

Not necessarily. A browser-based touchscreen test can check supported touch input without requiring a device-specific testing code.

Yes. A browser-based touchscreen test can be used on supported Samsung devices to check touch input.

Yes. You can use a browser-based touchscreen test to check supported Vivo devices.

Yes. A browser-based touchscreen test can help check touch input on supported OnePlus devices.

Yes. You can use a browser-based touchscreen test to check touch input on supported Redmi devices.

Yes. A browser-based touchscreen test can be used to check touch input on supported Oppo and Realme devices.

If vibration is supported by the device and browser, a vibration test can send a vibration command so you can check whether the device responds.

Browser support for vibration features varies by device and browser. If the required browser API is unavailable, the website cannot directly trigger the vibration motor.

Yes, where the connected controller and browser support the required gamepad vibration functionality.

A browser-based sensor test can display supported motion-sensor readings while you move or rotate the device.

Open the sensor test on a supported Android browser and allow sensor access if requested. The available readings depend on the device and browser.

If the browser provides access to the relevant motion-sensor APIs, you can use a browser-based sensor test to inspect gyroscope-related readings.

An accelerometer measures acceleration and changes in motion, while a gyroscope measures rotational movement. Devices can use both sensors together for motion and orientation features.

Supported browser APIs can provide access to some device sensors, but the sensors available to a website depend on the device, browser and permissions.

A sensor test can help you check whether supported motion readings are being detected, which can be useful when troubleshooting motion-controlled games.

A tone generator produces audio at a selected frequency, allowing you to test speakers, headphones and other audio equipment.

Yes. Different frequencies can be played through your speakers to help you check how they reproduce different parts of the audible range.

Yes. A tone generator can be used with headphones to play selected frequencies through the connected audio output.

A pitch detector analyses microphone input to estimate the fundamental frequency or pitch of a sound.

Yes. Test Your Gadget is designed to provide multiple browser-based device tests from one website, where supported by the browser and device.

Many browser-based tests do not require separate software installation, but available functionality depends on the browser APIs supported by your device.

Browser tests can provide useful information about whether a device feature is detected and responding, but they cannot replace specialised hardware diagnostics for every type of fault.

If a required browser API or device feature is unavailable, the test should indicate that the feature is unsupported rather than presenting a false result.
