Scan on Android with Camera, Lens, or a saved image
Open the Camera app, point it steadily at the QR code, and tap the banner that appears; many current Android phones recognize codes without a separate app. If nothing appears, use Google Lens from Camera, quick settings, or the Google app. For a screenshot or saved image, open it in Google Photos or Gallery and choose Lens or Scan QR. You can also upload the image to QRFlow's browser reader, where decoding stays on the device. Check focus, lighting, camera permission, and whether the whole quiet zone is visible. Preview any unfamiliar URL before opening it.
Try Camera first, then Google Lens if no banner appears.
Use Photos, Gallery, or the local reader for screenshots.
Preview unknown destinations before opening them.
在 Android 上用相机、Lens 或已保存图片扫码
打开相机 App，稳定对准二维码，然后点击出现的提示条；许多当前 Android 手机不需要单独安装扫码 App。如果没有提示，可以从相机、快捷设置或 Google App 打开 Google Lens。扫描截图或已保存图片时，在 Google 相册或系统相册中选择 Lens 或“扫描二维码”；也可以把图片上传到 QRFlow 的浏览器读取器，解码会留在设备本地。若仍失败，请检查对焦、光线、相机权限，以及二维码四周留白区是否完整。打开陌生网址前先预览目标。
先用相机，没有提示时再用 Google Lens。
截图可用相册、图库或本地读取器扫描。

How we verify this guide
Before this page is included in the public guide directory, its examples are compared with the payload produced by the linked QRFlow generator and with the export and scan-readiness controls available in the current build. Camera, lighting, paper, print size, and destination apps can still change the result, so important print runs should always be tested on the final material and real devices.
Most current Android phones can scan QR codes with the camera app, a quick-settings scanner, or Google Lens. Start with the camera, then use Lens or the browser scanner when the code is already saved on your phone.
A QR code can hide a misleading link. Read the preview, avoid unexpected login or payment prompts, and do not approve a Discord login QR that someone else sent you. For other devices, use the iPhone guide or computer guide.
Diagnose a business card QR code that won't scan: test the file, then fix size, quiet zone, contrast, glare, blur, vCard density, styling, or print damage.
