How to Scan a QR Code on iPhone and Android
Scanning a QR code takes about two seconds — once you know which app to open. Here's every method for iPhone and Android, plus how to scan a code from a screenshot and what to do when a code refuses to scan.
On iPhone
Open the built-in Camera app and point it at the code — no need to take a photo. A yellow notification appears at the top of the screen; tap it to open the link, join the WiFi network or save the contact. This works on every iPhone running iOS 11 or later (2017 onwards).
You can also add a dedicated scanner to Control Center: Settings → Control Center → add "Code Scanner". Swipe down from the top-right corner and tap its icon for an instant full-screen scanner.
On Android
On almost all modern Android phones (Android 9 and later), the stock Camera app recognizes QR codes automatically — point and tap the link that pops up. If yours doesn't:
- Google Lens — open the Google app and tap the Lens (camera) icon in the search bar, or long-press the home button and choose Lens. Lens reads QR codes flawlessly.
- Quick Settings tile — many phones (Samsung, Pixel, Xiaomi) include a "Scan QR code" tile in the swipe-down quick settings panel.
- Camera setting — on Samsung, make sure Camera → Settings → "Scan QR codes" is switched on.
Scanning a QR code from a screenshot or photo
What if the QR code is on your own screen — in an email, a PDF or a WhatsApp message — and you can't point your camera at it?
- iPhone: save or screenshot the image, open it in Photos, then touch and hold the QR code in the image — iOS offers to open the link. (iOS 15+.)
- Android: open the image in Google Photos and tap the Lens icon at the bottom — Lens decodes the QR from the picture.
When a QR code won't scan
- Too far or too close — hold the phone so the code fills roughly a third of the screen, about 30 cm away for a table sticker.
- Glare or low light — tilt the phone to kill reflections, or turn on the flashlight.
- Dirty lens — genuinely the most common cause. Wipe it.
- Low contrast or damaged print — a faded or scratched code may be beyond its error-correction limit. Ask for an alternative or type the URL if printed nearby.
- Tiny print — codes under 2 cm are hard for cameras to resolve; the problem is the print, not your phone.
A quick safety note
A QR code is just a link — and like any link, it can lead anywhere. Phones show you the URL before opening it; glance at it. Be cautious of stickers pasted over original codes on parking meters and payment stands, a known scam pattern. When paying, confirm the merchant name shown in your payment app matches the shop you're standing in.
