How to Use a Samsung Galaxy S8 as a Webcam

The short answer

Yes, a Galaxy S8 can work as a webcam, but not on its own. The phone has no built-in setting that makes a computer recognize it as a camera. You need a webcam bridge: an app on the phone that sends the camera feed, plus a companion program on the computer that receives it and presents it to your call software as a camera you can select. The two usually connect over a USB cable or your Wi-Fi network.

Some newer Android versions include a native USB webcam mode. The Galaxy S8's last official major update was Android 9, so that native option does not apply to this phone. A third-party bridge app is the practical route.

What to check before you start

• A bridge app that still supports Android 9. Older phones sometimes lose support in newer app releases, so check the app's listed requirements before you install it.
• A matching desktop client for your computer's operating system, from the same developer as the phone app. The phone app alone is not enough.
• A connection method. USB is usually more stable. Wi-Fi avoids a cable but depends on network quality, and both devices must be on the same network.
• Power. Streaming video drains the battery quickly, so plan to keep the phone charging. With a USB connection, the cable may also supply power.
• A way to hold the phone steady at eye level, such as a small tripod with a phone clamp.

No tested app recommendations or compatibility results were available for this guide. Confirm current Android 9 support with whichever app you choose.

Step-by-step setup

• 1. Install the bridge app on the Galaxy S8 and the matching client on your computer.
• 2. Open the phone app and allow camera access when Android asks. Allow microphone access too if you plan to use the phone as your mic.
• 3. For a USB connection, the app may require USB debugging. To turn it on, go to Settings > About phone > Software information and tap Build number seven times to unlock Developer options. Then open Developer options and switch on USB debugging. Accept the prompt that appears on the phone when you plug it into the computer.
• 4. For a Wi-Fi connection, make sure the phone and computer are on the same network. Then enter or select the phone's connection details in the desktop client, following the app's instructions.
• 5. Start the connection from the desktop client and confirm that a live preview appears there.
• 6. Open your video-call app or browser, go to its video settings, and select the camera the bridge program created. Its name usually matches the app's name.
• 7. Choose the microphone you actually want. That might be the phone, if the bridge supports audio, or the computer's own mic or a headset.

Verify that it really works

Each step can succeed while the next one fails, so check them separately.

• Camera access: the phone app has camera permission, and the call app or browser has permission to use a camera. Browsers ask per site, and computers may also have a system-level camera privacy setting.
• Video capture: you see a moving live image in the call app's preview, not a black frame or a frozen picture.
• Call quality: the image stays smooth and clear during a test call, with no long freezes or heavy blur. Quality depends on lighting and connection stability as well as the camera.
• Microphone detection: the microphone you picked appears in the call app's audio list.
• Input activity: the level meter moves when you speak.
• Intelligible sound: a test recording or a test call with someone else confirms your voice is clear, without echo or dropouts.

If the phone camera doesn't appear

• Restart the call app after the desktop client is running. Many apps only scan for cameras when they launch.
• Check that no other program is using the virtual camera or the phone's camera at the same time.
• On USB, try a different cable or port, and check that the debugging prompt on the phone was accepted.
• On Wi-Fi, confirm both devices are on the same network and that a firewall isn't blocking the desktop client.
• Re-check camera permissions in the browser's site settings and in the computer's privacy settings.

Limitations to expect

The phone can get warm during long sessions, especially while it is charging and streaming video. Give it some airflow. The rear camera generally gives a better image, but you can't see the phone screen while using it, so frame yourself using the computer preview. Wi-Fi setups may show more lag than a USB connection. Some features, such as higher resolutions, may depend on the specific app and its version, so check its documentation rather than assuming.

A note on backgrounds

Your background can be handled in two different ways. A physical background is whatever is actually behind you, so tidying the space or using a plain wall affects every frame the phone captures. A virtual background or blur is an effect applied by the call app, or sometimes by the bridge software, and how well it works depends on that software and your lighting. Neither is the same as editing the background of a still photo afterward.
