How to Scan a QR Code on iPhone and Android (No App Needed)
You don't need an app to scan a QR code. On an iPhone, open the Camera app and point it at the code, then tap the link that appears. On most Android phones, the camera does the same, or you can use the Scan QR code button in Quick Settings or Google Lens. Below are the exact steps for both, plus what to do when a code won't scan.
How to scan a QR code on iPhone
Method 1: the Camera app
- Open the Camera app from the Home Screen, Lock Screen or Control Center.
- Hold your iPhone so the QR code appears in the viewfinder. You don't need to take a photo.
- Tap the link or notification that appears on screen to open the content.
Method 2: Code Scanner in Control Center
Apple's Code Scanner opens straight from Control Center, without going through the Camera app.
- Open Control Center.
- Tap the Scan Code button.
- Point it at the QR code, then tap the link.
Don't see the button? Open Control Center, touch and hold the background, tap Add a Control, then choose Scan Code.
How to scan a QR code on Android
Android phones vary by brand, but at least one of these three methods works on almost every recent device.
Method 1: the Camera app
- Open the Camera app.
- Point it at the code, keeping the whole code visible.
- Wait a moment for a bubble or link to appear, then tap it.
On Google Pixel phones, make sure Camera scan suggestions is turned on in the camera's settings. On other brands, look for a "Scan QR codes" or "Google Lens" option in the camera settings.
Method 2: the Quick Settings tile
- Swipe down from the top of the screen to open Quick Settings.
- Tap Scan QR code. If it's not there, swipe left or tap the pencil icon to add it.
- Point the scanner at the code.
Method 3: Google Lens
Open the Google app or Google Lens and point it at the code. Lens can also read a QR code from a screenshot or photo in your gallery. We explain that in detail in how to scan a QR code from a picture.
QR code not scanning? 8 quick fixes
| Problem | Fix |
|---|---|
| Nothing happens | Hold still for two seconds and keep the whole code, including its white border, inside the frame. |
| Too close or too far | Move back until the code fills about a third of the screen. |
| Dark room | Add light, or turn on your phone's flashlight. |
| Glare on glossy paper or a screen | Tilt the phone slightly to remove the reflection. |
| Dirty lens | Wipe the camera lens. It fixes more problems than you'd think. |
| Scanning disabled | Check the camera settings for a QR or Lens option and switch it on. |
| Damaged or tiny code | The code may be printed too small or with poor contrast. Ask for the link instead. |
| Scans but the page doesn't load | The link may be broken or the code expired. See why QR codes stop working. |
Is it safe to scan any QR code?
A QR code is just a shortcut to a link or a piece of text, so treat it like a link in an email. Before tapping, read the web address in the preview. Be careful with codes stuck on top of other codes (on parking meters, for example), and never enter passwords or payment details on a page you reached from an unknown code. Our QR code security guide covers the common scams.
For businesses: make your codes easy to scan
If customers struggle to scan your code, the problem is usually the code, not their phone. Keep these rules in mind:
- Print it large enough. Follow our QR code size and print guidelines.
- Use strong contrast: a dark code on a light background.
- Leave a clean white margin (the "quiet zone") around it.
- Add a short call to action like "Scan for the menu".
- Always test it before printing, on both an iPhone and an Android phone.

What happens after you scan
A QR code can contain different kinds of data, and your phone reacts differently to each:
| Code type | What your phone does |
|---|---|
| Website link | Shows the address, then opens it in your browser |
| Wi-Fi network | Offers to join the network, no password typing |
| Contact card (vCard) | Offers to save the contact |
| Phone number or SMS | Opens the dialer or a pre-filled message |
| Opens a pre-written email | |
| Location | Opens a maps app on the spot |
| Payment code | Opens the matching payment app, where you confirm |
Learn more about these types in our guides to Wi-Fi QR codes and vCard QR codes.
Scanning a code from a screenshot or photo
Sometimes the code is on your own screen: in an email, a PDF ticket or a social post. You can't point your camera at your own screen, but you can still read it:
- Android: take a screenshot, open it in Google Photos or the gallery, and tap the Lens button.
- iPhone: take a screenshot and open it in Photos; recent iOS versions can detect codes and text in images.
Step-by-step instructions are in how to scan a QR code from a picture in your gallery.
Older phones and special cases
- Older iPhones and Android phones may not scan from the camera. Updating the operating system usually adds the feature. If that's not possible, a reputable scanner app from the official app store works.
- Work phones with restricted cameras may block scanning; ask your IT team.
- Tablets scan the same way as phones, but large tablets are harder to hold steady.
- Laptops rarely scan with the webcam; use your phone.
Choosing a safe scanner app
If you must install an app, choose one from the official App Store or Google Play with clear privacy information, and avoid apps that request access to your contacts or location without a reason. Many free scanner apps exist mainly to show ads; your built-in camera is usually the better choice.

Can I scan a QR code that's on my own screen?
Yes, with Google Lens on Android, or by taking a screenshot and opening it with a tool that reads codes from images.
Why does my phone show the link but not open it?
