Tap the URL bar. If Auto Fullscreen is enabled and the URL bar is not showing, scroll up to display it.

Tap the QR icon in the top left corner of the URL bar.

Focus the QR barcode you want to read in the square that appears on the screen.

The QR scanner will read the barcode automatically.

If it is too dark for the QR scanner, you can turn on the camera light with the toggle at the top of the screen.

If the QR barcode you want to read is on a photo in your gallery, tap “Photos”. Choose the correct photo and adjust it so the QR barcode fills the highlighted square.
