To scan a QR code, use a supported camera or code-reading function on your phone, place the whole symbol in view, and follow the action it identifies. The exact controls depend on your device and software version.
Start with the phone's supported reader
Apple describes scanning through Camera or Control Center in its iPhone guide. On other devices, check the manufacturer's current instructions for the model you use. Do not assume that every camera app exposes the same controls.
- Use enough light for the camera to see the full code.
- Keep the code flat and avoid covering its edges or clear margin.
- Adjust the distance gradually until the camera focuses.
- Read the identified destination or action before opening it.
A screenshot is a different situation
If the code is already on the same screen you want to scan from, a live camera cannot point at that screen. Use a supported saved-image recognition feature if the device provides one, or show the image on another device. Follow the actual phone's guidance rather than assuming every photo app can read codes.
Separate the scan from the destination
If a link appears but the page will not open, the reader has already done its job. Check connectivity, whether the link is current, and whether the destination requires permission. A request to sign in is not necessarily a printing problem.
For example, a product manual can scan successfully but remain private to its owner. When creating your own code with YouQR, test the destination while signed out before putting it on packaging.
Frequently asked questions
Must I install a scanner app?
Use your phone's supported built-in option where available. Requirements depend on the device and the kind of code.
Why is nothing detected?
Check focus, light, print clarity, contrast and whether the whole symbol is visible.
Does an online link need mobile data or WiFi?
It needs a working network connection, even if the pattern can be decoded offline.
Does every scan open a website?
No. A code may contain text, contact, payment, network or other supported data.
