How to scan a QR code with any phone
Scanning a QR code today requires no extra app: any modern phone camera does it on its own. Still, some situations are confusing (what if the QR code is on my own screen?). Here is the complete guide.
On iPhone
- Open the Camera app (works since iOS 11 — any iPhone from the 5s onward, updated).
- Point at the code; no need to take a photo.
- Tap the yellow notification that appears at the top to open the link.
You can also add the "Code Scanner" to Control Center (Settings → Control Center) for a dedicated reader.
On Android
- Open the Camera app and point at the code. On most phones since Android 9-10, the link appears directly.
- If it does not, press the Google Lens button (in the camera itself or in the Google search bar) and point at the QR.
- Last resort: swipe down to Quick Settings; many Android phones include a "Scan QR code" shortcut.
What if the QR code is on my own phone's screen?
You cannot point your phone at itself, but you can:
- iPhone: take a screenshot, open the Photos app and long-press the QR code in the image — Live Text will recognize it.
- Android: take a screenshot and open it with Google Lens (the Lens icon in Google Photos), or share the image directly to Lens.
When the code will not scan
- Clean the lens and move back a little: the whole QR should fit on screen with a margin.
- Find light: glare on plastic and screens is enemy number one.
- Check size and contrast: codes that are too small, blurry or printed in light-on-light colors can be unreadable.
- Update your system: on old phones, install a QR reader app from a trusted developer.
Watch out for "quishing"
Just like email phishing, there is fraud using QR stickers pasted over the original ones on parking meters, posters or menus. Before opening the link, look at the URL in the notification: be wary of odd domains or link shorteners when the context does not justify them, and never enter banking details on a page you reached from a random street QR.

Frequently asked questions
Do I need an app to scan QR codes?
On phones from recent years, no: the camera on iPhone (iOS 11+) and most Android phones (9/10+) recognizes them automatically. Only older phones need a reader app.
How do I scan a QR code from a photo or screenshot?
On iPhone, long-press the code inside the Photos app. On Android, open the image with Google Lens. Both recognize the QR without using the camera.
Why doesn't my camera detect the QR code?
Most common causes: poor light or glare, a code that is too small or damaged, a dirty lens, or an older phone without built-in detection. Try Google Lens or a reader app.
Is it dangerous to scan an unknown QR code?
Scanning by itself installs nothing, but the link can lead to a fraudulent site. Always check the URL before opening it and never enter passwords or payment details on pages you reached via a QR code of dubious origin.
