How to Scan a QR Code on iPhone, Android, and From a Screenshot

How to scan a QR code on iPhone

Open the Camera app and point it at the QR code. Hold the phone steady for a second and a banner should appear near the top of the screen. Tap that banner to open the link. If nothing happens, make sure the full code is in frame and the camera is focused properly.

How to scan a QR code on Android

Most newer Android phones can scan QR codes directly from the main camera app. If your phone does not react, open Google Lens and point it at the code instead. On many devices, that solves the problem immediately.

How to scan a QR code from a screenshot or photo

If the QR code is saved as an image, open it in Photos or Google Photos and use the built-in scan or Lens feature. This is the easiest method when someone sends you a QR code in WhatsApp, email, or a screenshot instead of showing it live on another screen.

Why scanning sometimes fails

• The camera lens is slightly dirty or out of focus.
• The code is too small or partly cut off in the frame.
• There is glare on a printed surface or the screen brightness is too low.
• The camera app you are using does not support QR recognition directly.

What to try if the phone still will not scan

Move closer, then slightly farther away, so the camera can refocus. Increase the brightness if the code is on another screen. Reduce glare if it is printed on glossy material. And if the code is yours, double-check that the destination still works and the print is not damaged.

If you create QR campaigns yourself, use dynamic QR codes so you can update the destination without reprinting. Create your first QR code, or read the full scan-fix guide if the issue is with your own printed code.
