Most phones have a far better camera than a laptop’s built-in one. You can use it for video calls, lessons or streaming.

Option 1: Android over USB

Many recent Android phones can act as a webcam directly.

1. Connect the phone to the computer with a USB cable.
2. Pull down the notification shade and tap the USB notification.
3. Look for a Webcam option and choose it.
4. On the computer, open your calling app and select the phone as the camera.

This depends on the phone and the Android version. If you do not see a Webcam option, use an app (below).

Option 2: iPhone with a Mac

Recent iPhones and Macs can work together as Continuity Camera. The two devices need to be signed in to the same Apple account, near each other, with Wi-Fi and Bluetooth on. On the Mac, choose the iPhone as the camera in your calling app.

Option 3: a webcam app

Apps from trusted makers can turn a phone into a webcam on Windows or Mac, over USB or Wi-Fi. Install the app on both phone and computer, follow the pairing steps, then pick the phone as the camera. Use only well-known apps, and read what permissions they ask for.

Tips for a good picture

1. Prop the phone up at eye level with a stand or a pile of books. Use landscape mode.
2. Light your face from the front, such as a window or a lamp, and not from behind.
3. Clean the lens with a soft cloth.
4. Keep it plugged in. Video drains the battery fast, and a charged, cool phone works better: see how to make your phone battery last longer.
5. Silence the phone so calls and alerts do not interrupt.

Privacy checklist

• Use apps only from official stores and well-known developers.
• Stop the app when you finish, and check that the camera is not left on.
• Do not give an app more permissions than it needs.
