Modern Xiaomi, Redmi and POCO smartphones have become versatile tools that can replace many individual gadgets, including barcode scanners. Users often face a situation where you need not just read the information from the sticker, but save its visual representation in the gallery for subsequent analysis or transfer, this may be necessary when you file documents, fix price tags or save data to log into the Wi-Fi network.
The process of creating a codeshot on devices with a MIUI shell or HyperOS has its own nuances, depending on the version of the software and the model of the installed camera module. The standard application often tries to automatically recognize the content, but sometimes the user needs a raw image file. Understanding the differences between scanning mode and conventional photography will help avoid confusion and time loss.
In this guide, we will discuss in detail all available fixation methods QR-From standard tools to third-party applications, you will learn how to set up a camera to capture small codes macro and what hidden features can be useful in non-standard situations.
The difference between scanning and photography on Xiaomi
Many smartphone owners confuse scanning and photography, although technically they are different actions. Scanning involves instant processing of the image by the processor and the output of the result (links, text), while photography saves a graphics file. In Xiaomi and Redmi smartphones, different modules of the system often answer for these functions.
When you point your camera at the code, the built-in Google Lens algorithm or proprietary MIUI scanner tries to read the data in real time. If you're targeting a photo, you need to ignore the pop-up prompts and use a standard shutter, and the quality of the final shot depends on the correct focus and lighting.
⚠️ Warning: When trying to photograph code from another device, avoid moire (colored stripes). To do this, slightly change the angle of the smartphone or the distance to the subject.
To get a clear image, it is important to stabilize your hands or use a tripod, as even minimal shaking can blur the boundaries of squares. Modern camera sensors in Xiaomi’s flagship models do this perfectly, but budget devices may require more careful tuning.
Use of the standard Camera application
The fastest way to capture QR-code to use the built-in application. Most current versions of the HyperOS shell and MIUI The recognition algorithms are built right into the viewfinder, but you have to do a few simple things to create a picture.
Launch the Camera app and switch to Photo mode. Point the lens to the code so that it is in the center of the frame. QR-structure, which may be indicated by a slight vibration or the appearance of a yellow frame, but you do not need to press it if the target is a photo.
Press the shutter button. The image will be saved in the gallery. If the code is very small, such as on a small electronics package, you may need to switch to Macro mode (flower icon), which will allow you to bring the smartphone close and keep the details clear.
- 📸 Open the Camera app and select Photo mode.
- 🎯 Point the camera to the code, wait for autofocus.
- 🖼️ Press the shutter button to save the photo.
- 🔍 For small codes, turn on Macro mode.
It is worth noting that in some regions on global firmware versions, scanning functions may be limited, in which case the system will offer to install a plugin or use Google Lens, but the basic photo shooting function will remain available forever.
Focus setting for small codes
A common problem with taking codes is that you can't focus at close range. A standard lens has a minimum focusing distance, and if you bring the phone closer, the image becomes blurry. And here you have specialized modes to help.
In the camera interface, find a flower icon or Macro inscription. Activation of this mode switches the camera to a wide-angle module with the ability to focus at a distance of 2-5 cm.
If automatic focusing is not working, you can use manual tuning. Tap the screen in the area where the code is located to set the focal point. In professional mode (Pro), you can manually twist the focus to the minimum value indicated by the flower symbol.
💡
To shoot very small codes, wipe the camera lens with a soft cloth – greasy spots often prevent autofocus from correctly determining the boundaries of contrasting black squares.
Using digital zoom is not recommended, as it simply cuts the picture, reducing the quality, it is better to zoom in on the smartphone or use macro mode, which engages wide-angle optics.
Specialized Scanner Mode in MIUI
In the shell. MIUI There's a separate system application called Scanner, which is often confused with a camera, and it's designed to read data, but it has a history-saving function, and you can find it in the Tools folder or search it.
When you start the scanner, you see an interface that looks like a camera, but with an optimized code search algorithm, and there's a gallery button that allows you to upload a photo you already have, and a flash button, and the main difference is that after reading, the code is stored in history inside the application.
To take a picture through this module, you need to press the shutter button. However, unlike a conventional camera, decoding is given priority here. If the code is damaged or poorly lit, the application may not take the picture, trying to endlessly read the data.
| Function | Appendix Camera | Appendix Scanner |
|---|---|---|
| Main objective | Photo/video production | Data reading |
| Gallery preservation | Automatically. | Only through history. |
| Macro regime | Got it (manual/auto) | Depends on the version. |
| Working without a network | Complete. | Partial |
For tasks that require a visual copy of a document or code sticker, the standard camera app is better suited due to its versatility and the absence of unnecessary restrictions on decoding.
☑️ Readiness to shoot code
Shooting codes from the screen of another device
Often there is a need to take a picture. QR-A code displayed on a computer monitor or another smartphone screen, in which case the laws of display optics come into force. The screens have a refresh rate that can conflict with the camera shutter speed, causing bandwidths to occur.
To get a clean shot, try changing the brightness of the source screen. Too high a brightness causes white sections of code to light up, making it unreadable. Optimally set the brightness to 50-70%.
Use the regimen. HDR This mode takes multiple shots of different exposures and combines them, which helps to save details in both light and dark areas of code. OLED-screen.
⚠️ Warning: Do not use a digital flash when shooting from the screen of another device. The light from the display matrix will completely destroy the contrast of the code, and the photo will become useless.
If the bands in the image remain, try changing the distance to the object, sometimes just push the phone 10-15 centimeters further, so that the frequencies synchronize and the bands disappear.
Use of Google Lens (Google Lens)
An alternative to built-in tools is Google Lens, which is often integrated into Xiaomi’s camera or available as a standalone app. It offers powerful image analysis tools before saving.
When you run Google Lens through the viewfinder, you get access to augmented reality. You point the camera at the code, and the system will suggest actions: open a link, save a contact, or copy text. To create a photo, you just need to press the shutter button in the lens interface.
The advantage of this method is that it can edit and recognize text on the fly. QR-The code contains textual information, Google can recognize it even without fully decoding a square, just by analyzing the image.
What if Google Lens doesn’t see the code?
The app requires an internet connection to work properly, as the data processing takes place on Google servers, a point to consider if you are in a poor network coverage zone.
Third-party applications for complex cases
If Xiaomi’s standard tools fail to do the job (e.g., code is corrupted, flipped, or has a non-standard color), specialized apps from the Google Play Store will come to the rescue, using more aggressive image binary algorithms.
Popular solutions like QR & Barcode Scanner or Binary Eye allow not only reading but also saving scan history with previews, some of which have a "Continuous Scan" mode that constantly analyzes the flow from the camera.
Installing third-party software gives you access to manual shutter speed and ISO settings, which is not possible in base mode, and this allows you to “pull” the code image in extremely low light conditions, where Xiaomi automation is surrendered.
- 📥 Download the proven app from the Play Store.
- 🔒 Check the permissions requested (camera, memory).
- ⚙️ Set up the scan sensitivity in the menu.
- 💾 Save the result in format JPG or PNG.
However, it is worth remembering security: do not use unknown scanners for codes leading to financial services, as in theory they can intercept data.
💡
For most tasks, a standard Camera application in Photo mode is enough, but for damaged codes it is better to use specialized software.
