What is Android's USB webcam mode?

Android's USB webcam mode is a built-in setting that makes a phone present itself over a USB cable as a standard camera, with no app on the computer. The standard is called UVC, short for USB Video Class. Google's documentation says it is supported on devices running Android 14 QPR1 or higher, lists macOS among the computers it can work with, and says the phone maker has to switch it on. So it is real, it is free, and it works on some phones and not others. If yours lacks it, an app is the route.

Did Google actually ship it?

Yes, in the sense that it is documented as part of Android. Google's Android Open Source Project page, checked 26 October 2026, says: "For devices running Android 14 QPR1 or higher, Android supports using the device as a USB webcam." The page is written for phone makers. It says the DeviceAsWebcam service is enabled when a maker sets a build property to true, and that a Webcam option then appears in the Settings app under USB preferences.

It shipped on Pixel phones in a form you can use. Google's Pixel Camera help has a page titled "Use your Pixel phone as a webcam." The Android page does not name any phone that has it, and the Pixel page does not list models or Android versions, so we cannot give you a list of supported phones. Check your own phone, as described below.

What does UVC mean?

UVC is a standard way for a USB camera to introduce itself to a computer, and ordinary USB webcams use it. Android's page says devices with this feature "are advertise as a UVC device" (the page's own wording), so the computer treats the phone as it would any USB webcam. Google's Pixel page says the webcam works on any device "that has USB Video Class (UVC) support implemented," and gives laptops, TVs, and cars as examples.

Does it work on a Mac?

Google's Android page names macOS as one of the USB hosts, with Linux, Windows, and ChromeOS. It also gives a macOS limit: "Android devices in webcam mode don't work with USB 3.0+ cables on macOS hosts because of a bug with Apple's UVC driver." In practice, if your Mac does not see the camera, try a different cable, preferably a plain USB 2.0 one.

The Pixel page does not mention macOS. We have not tested it on a Mac, and nothing here is a promise. Try it for five minutes.

How do I turn it on?

On a Pixel, per Google's help page:

1. Connect the phone to the Mac with a data-supported USB cable, as Google's page puts it.
2. On the phone, tap the notification that says "Charging this device through USB."
3. Under "Use USB for," choose Webcam.
4. On the Mac, open a video app and choose the phone as your camera.

On a phone from another maker, open the same USB notification and look for a Webcam entry. If there is none, the maker has not enabled it. We could not open Samsung's support pages, so check your phone's own help pages.

If your Mac asks to approve a new USB accessory, say yes. Apple's accessories page says that on Mac laptops with Apple silicon you might need to approve new accessories, and that if you click Don't Allow, your Mac "won't recognize the accessory", though it can still charge.

What are the limits?

Google's Pixel page lists some:

• "When you receive a video call or use an app that requires a camera, webcam stream pauses."
• "Currently, you can't use your phone as a webcam for other Pixel devices."
• "UVC cameras aren't supported by Pixel devices," meaning a Pixel cannot use another UVC camera as input.

Neither page says anything about picture quality, resolution, or the phone's microphone, so do not assume you get the rear camera at full quality or sound from the phone. Check in your video app.

When do I need an app instead?

When your phone has no Webcam entry, when you want a wireless connection, or when you want the phone's microphone and extra picture controls. Options include Camo, Iriun, and DroidCam with OBS (see the comparison). The Relay, a paid app from the publisher of this site, also puts the phone's camera and microphone on the Mac as a camera and a microphone, over your own Wi-Fi network with Bluetooth as a fallback. See Android phone as a Mac webcam. It has no USB cable mode. If the built-in mode works for you, you may not need it. The Relay is one subscription through Google Play that covers your phone and your Mac, with a 7-day free trial.

Questions people ask

Is Android's USB webcam the same as DroidCam?

No. DroidCam is an app. The USB webcam mode is part of Android itself and needs no app on the Mac.

Does my Samsung phone have USB webcam mode?

We could not confirm it from Samsung's pages. Plug in a cable and look for a Webcam option in the USB notification. Our Samsung webcam guide has more.

Why does my Mac not see the phone as a camera?

Check that you chose Webcam in the USB options, that the cable is a data cable, and that you approved the USB accessory if the Mac asked. Google says USB 3.0+ cables do not work for this on macOS, so try another cable.

Can I use the phone's microphone in webcam mode?

Neither Google page says. Check the audio input in your video app. If you want the phone's microphone for certain, an app that carries audio is the safer route.
