Xiaomi Redmi 8 Pro – budget smartphone with a good camera, which perfectly copes not only with photos, but also with scanning QR-But many people don't know that the scanning functionality is built into the default system and doesn't require third-party applications. In this article, we'll look at all the ways to scan on Redmi 8 Pro, including hidden chips. MIUI, setting up the camera for better recognition and solving typical problems.

The Redmi 8 Pro features a direct scanning capability through the standard Camera app (without additional plugins) and a built-in Scanner app (in some regions it may be called Mi Scanner), with recognition quality depending on the lighting, tilt angle, and even the MIUI firmware version. We tested all methods on current versions of the software and found the best settings for different types of code.

1. Scanning. QR-codes through a standard camera

The fastest way to scan QR-The code on Xiaomi Redmi 8 Pro is to use the built-in camera. The code recognition function is activated by default, but it can be turned on/off in the settings. Here's how it works:

If QR-code on the screen of another device, reduce the brightness of the second screen – this will reduce glare and improve recognition.

2.Use of the built-in Scanner application (Mi Scanner)

On some firmware MIUI The Scanner (or Mi Scanner) application is preinstalled, which can recognize not only the scanner QR-codes, but also barcodes, and also save the scanned data to history:

  1. Open the Scanner from the app menu (if not, install the official Xiaomi Scanner app from the Play Market).
  2. The app automatically detects the type (QR, EAN, PDF417, etc.) and suggests an action.
  3. Product barcodes may require manual focusing – tap the screen in the code area.

The Mi Scanner has the advantage of supporting scanning documents (passports, driver's licenses) with automatic framing and clarity improvements, but in some regions this application is not out of the box - it needs to be downloaded separately.

  1. Rub the code with a napkin (remove glare).
  2. Take a picture of it and zoom in on the gallery.
  3. Use the Google Lens app (recognizes even partially erased codes).
Why is the black box barcode not scanned?
On dark surfaces (black plastic, cardboard), the barcode can merge with the background, so you can light the code on the side with a flashlight or point the lamp light at a 45Β° angle to it, and increase the contrast in the camera settings (HDR mode).

4. Document scanning (passport, receipts, tickets)

  3. Activate manual focus: tap the screen in the text area and hold until the AE/AF Lock is written.
  4. Take a picture, then trim the edges in the Gallery app (Pruning Tool).

  • 🎯 Focus: Use a manual focus (touch the screen and hold until it appears) AE/AF Lock).
  • πŸŒ“ Exposure: Reduce brightness (slider down) if the code is on a light background.

To scan small barcodes (for example, on medications):

  1. Activate macro mode (if available) or use Ultra-wide lens (switch to 0.6x in camera).
  2. Increase the zoom to 1.5x-2x, but no more, otherwise there will be noise.
  3. Take a few pictures and choose the clearest one.

πŸ’‘

If you scan code on a curved surface (like a bottle), use Panorama mode in the camera – it better copes with distortion.
