How to Scan QR Codes on iPhone & Android (2026 Guide)
Most smartphones can scan QR codes using just the built-in camera — no special app needed. Here's how to do it on every major platform, plus tips for when it doesn't work.
Scanning QR Codes on iPhone (iOS)
Every iPhone running iOS 11 or later can scan QR codes directly from the Camera app — no extra app required.
- Open the Camera app
- Point the camera at the QR code — keep it steady within the frame
- A notification banner will appear at the top with the QR code content (usually a URL)
- Tap the banner to open the link or take action
If it doesn't work, go to Settings → Camera and make sure "Scan QR Codes" is enabled.
Using the Code Scanner (Control Center)
iOS also includes a dedicated Code Scanner in Control Center. Add it via Settings → Control Center → Code Scanner. This scanner opens links automatically and works better in low light since it activates the flashlight.
Scanning QR Codes on Android
Most Android phones running Android 9 (Pie) or later support QR code scanning from the camera, though the experience varies by manufacturer.
Samsung Galaxy
- Open the Camera app
- Point at the QR code
- A popup will appear with the link — tap to open
If it doesn't work: Open Camera → tap the Settings gear icon → enable "Scan QR codes".
Google Pixel / Stock Android
- Open the Camera app
- Point at the QR code
- A chip/link will appear on screen — tap it
Alternatively, use Google Lens: open the Camera, tap the Lens icon, and point at the QR code.
Other Android Phones
Most brands (OnePlus, Xiaomi, Oppo, Huawei) support camera-based QR scanning. If your camera doesn't detect QR codes automatically, open Google Lens from the Google app or download a dedicated scanner like Scan & Generate.
Quick Scan from Lock Screen
- iPhone: Swipe to open the Camera from the lock screen and point at a QR code — it works without unlocking
- Android (Pixel): Long-press the QR code tile in Quick Settings (Android 13+)
- Samsung: Add the QR scanner shortcut to Quick Settings for instant access
What If the QR Code Won't Scan?
Common reasons and fixes:
- Too far or too close: Hold your phone 10–30 cm from the code. Fill about 60–80% of the viewfinder
- Poor lighting: Use the flash or move to a brighter area. Avoid glare on glossy surfaces
- Damaged or blurry code: If the code is scratched, faded, or partially obscured, it may not have enough intact data for scanning
- Low contrast: QR codes need clear contrast between dark modules and light background
- Camera focus: Tap the screen to refocus if the camera is struggling to lock on
- Very dense codes: QR codes with lots of data (long URLs, vCards) may need a higher-resolution camera or closer positioning
Scanning QR Codes from Screenshots & Images
You can also scan QR codes from saved images:
- iPhone: Open the image in Photos, use Live Text (iOS 15+) — it detects QR codes in images
- Android: Open the image and share it to Google Lens, or use a scanner app with image import
- Scan & Generate app: Supports scanning from gallery images, screenshots, and files
