What is a QR Code?
A QR code (Quick Response code) is a type of two-dimensional barcode that stores information like website links, text, phone numbers, contact details, or WiFi passwords. You can scan a QR code with your Android phone camera to instantly access that information without typing anything.
QR codes are used everywhere today — on menus, products, business cards, billboards, event tickets, and payment systems.
Method 1: Using the Built-in Android Camera
Most Android phones running Android 8 (Oreo) or higher can scan QR codes directly using the default camera app:
- Open your Camera app — tap the camera icon on your home screen or in the app drawer.
- Switch to photo mode — make sure you're in the regular photo mode (not video or selfie).
- Point the camera at the QR code — hold your phone 6–10 inches away from the code and keep it steady.
- Wait for the notification — a link or banner will appear at the top or bottom of the screen.
- Tap the notification to open the link, view the text, or take the action stored in the QR code.
Note: If this doesn't work on your phone, the feature may be disabled or your phone model may not support it. In that case, use Method 2 below.
Method 2: Using a Dedicated QR Scanner App
A dedicated QR scanner app works on all Android versions and gives you more features — including scan history, barcode support, and easy copy/share options.

Tips for Better Scanning
- Good lighting — Make sure the QR code is well-lit. Avoid scanning in very dark conditions.
- Keep steady — Hold your phone still while scanning to avoid blur.
- Correct distance — Hold your phone 6–12 inches from the QR code for best results.
- Clean camera lens — A smudged camera lens can cause failed scans. Wipe it gently.
- Full code in frame — Make sure the entire QR code is visible within the camera frame.
