How to scan a QR code that’s displayed on your screen There’s also usually no real need to choose a paid QR code scanner app, but note that the free ones tend to be ad-heavy, and it can be easy to accidentally tap an advert rather than the QR code link, so double check you’re tapping the right thing. The exact process will vary from app to app, but will be broadly in line with the methods above – once you’ve opened the app and got its QR scanning screen displayed, just point your camera at the QR code and it should automatically scan and provide you with a link to the contents. As with any other method for scanning a QR code though, you will typically need an internet connection for it to work. Tap on that to head to the website or other location hidden within the code.


Point Google Lens at the QR code for a second or two and it will highlight the code and display a link to its contents. This looks a bit like, well, a camera lens. To activate this, just launch Google Assistant (usually by saying “Hey, Google”, or long-pressing the home button), then tap the Google Lens icon.

Some phones also require you to enable QR code scanning on their main settings screen, so you might have to do some digging. To do this, tap the Bixby Vision icon in the top left corner of the camera app. Note that on some Samsung phones you’ll also need to enable Bixby Vision within the camera before QR code scanning will work.
