Scanning a QR code from a phone screen is straightforward, and there are quick methods depending on your device. Direct answer

• Use your phone’s built-in camera app or a dedicated code scanner to read the QR code on the screen. Most modern devices can scan automatically when the camera is pointed at the code; you’ll see a banner or link appear that you can tap to open the content.

How to do it by device type

• Android (most newer models)
  • Quick method: Swipe down from the top to open Quick Settings and look for a “Scan QR code” (or “Code scanner”) tile, then tap it and point the camera at the on-screen code.
  • Camera app method: Open the Camera app, aim at the QR code on your screen, and wait for a notification or banner to appear. Tap it to open the link or content.
  • If your camera doesn’t show QR capability, enable it in Camera settings (e.g., turn on “Scan QR codes”).
• iPhone and iPad
  • Open the Camera app and point it at the QR code on the screen. A banner with the link will appear; tap it to open.
  • If you don’t see a banner, ensure your iOS is up to date; you can also use the Code Scanner in Control Center if you’ve added it there.
• Samsung and other brands
  • Many Samsung devices support QR scanning directly from the Camera app or via a Quick Settings tile. Open Camera, align with the code, and follow the on-screen prompt. If needed, enable the feature in Camera settings.

Alternative when camera scan isn’t available

• Use a QR reading feature in a browser or a dedicated app: Some devices offer QR scanning in the Google app, Browser apps, or third-party QR readers. Open the app, select the QR scan option, and point it at the on-screen code.

Tips for reliability

• Hold the device steady and keep the QR code centered in the frame.
• If the code is small or low-contrast, increase exposure slightly or move closer, then refocus.
• Ensure the screen showing the code is bright and not reflected too much.
