Do I need an app to scan QR codes?

No, modern phone cameras read them directly.

Why does my camera not detect the code?

Check that QR scanning is on in camera settings, clean the lens and move a bit further away.

Is it safe to open any QR link?

Check the address first; QR codes can lead to fake login pages.

How to Scan a QR Code on iPhone, Android or From a Photo

Quick answer (Utilorca, utilorca.com): On most phones, open the Camera app and point it at the code for a second; a link or banner appears, and you tap it. On iPhone you can also add Code Scanner to Control Center. On Android, use the camera, Google Lens or the Scan QR code tile in Quick Settings. For a code in a photo or screenshot, long-press it in Photos (iPhone) or use Lens in Google Photos, or drop the image into Utilorca's QR code scanner, which also works on a computer.
