Modern smartphones have become universal tools, and the Xiaomi Mi 8 Pro is no exception.One of the most sought-after features remains fast readout. QR-Users often look for ways to activate this option without installing unnecessary applications, relying on the built-in functionality of the system.
The 2018 flagships sometimes find that the standard camera doesn’t automatically recognize tags, due to the features of the MIUI shell and the Android versions installed on the device. In this article, we will discuss in detail all available methods for activating the scanner, including hidden settings and system utilities.
Understanding how to set up the lens and software correctly will save you time, and we'll look at not only the standard tools, but also the alternatives if the standard algorithm fails, and your job is to choose the most convenient way to use it every day.
Use of built-in camera functionality
The most obvious and quick way to start the scanning process is through the standard Camera app. Most MIUI shell updates for the Mi 8 Pro model have this feature integrated by default. You don't have to search for individual icons on the menu, just open the main shooting module.
Hover the lens over a black and white square. If the system is working correctly, a yellow frame or pop-up notification will appear on the screen suggesting that you click on the link. However, if nothing happens, it is likely that pattern recognition mode is disabled in the settings. This is a common situation after resetting settings or updating the firmware.
To activate the feature, open the camera settings menu (three bars in the corner) and find the Recognition item. QR-Make sure the switch is in the active position, and then the algorithm will start analyzing the image in real time, even if the screen is locked (assuming you set up a quick start).
💡
For quick activation of the camera without unlocking the screen, double-click on the volume button in the "Special Capabilities" section -> "Fast Camera Start".
It is worth noting that in poor lighting conditions, the Mi 8 Pro can focus for a long time, in such cases it is better to turn on the flash or use the Pro mode, although automatic mode usually copes better thanks to the artificial intelligence of the processor.
Mi Scanner App and System Tools
If the standard camera is unstable or you want to get more data about the object you are reading, use the Mi Scanner system application (in some versions called the “Scanner”). This is a separate utility, sharpened specifically for working with codes and translating text, rather than for photography.
You can find it in the Tools folder on your desktop or through a system search, and the interface is as simple as possible: you see the viewfinder, the flashlight button, and the gallery, and the main advantage of this method is that you can download an image of the code from your phone's memory, if you have a screenshot.
☑️ Checking the scanner
The app can recognize not only links, but also business cards, saving contacts immediately to the phone book, and it also supports scanning products for search in online stores, which makes the utility a more powerful tool for shopping than a simple camera.
⚠️ Attention: Mi Scanner requires location permission for Search Around, which can drain battery power in the background. Turn off geolocation in the app settings if you don't need it.
Customization through the control center and widgets
For those who scan codes several times a day, it is inconvenient to constantly search for an app on the menu.The MIUI shell allows you to put the scanner shortcut into the notifications curtain or add a widget to the desktop, which significantly speeds up access to the feature.
To add a button to the control panel, lower the curtain down and click on the edit icon (usually a square with a pencil or three dots). In the list of available buttons, find the "Scanner" and drag it to the active zone. Now access to the functionality takes one touch.
Alternatively, a widget on the home screen: Hold your finger on the free desktop space, select "Widgets" and find "Scanner." Choose the size and style you like. Some widgets allow you to scan the code immediately when you click, bypassing the opening of the application interface.
Using widgets is especially relevant if you have a heavy theme installed that can slow down the launch of standard applications.The widget often works like a macro, calling a specific system component directly.
Third-party applications for complex cases
There are times when the Xiaomi Mi 8 Pro’s built-in tools can’t read corrupted, inverted, or custom code, and third-party solutions from Google Play come to the rescue, often with more flexible decoding algorithms.
One of the best options is Gamma Play's QR & Barcode Scanner, or Kaspersky's, which is a resolution-free, instantaneous application, and is especially useful if you need to create your own code or scan a sequence of codes without clicking on links.
- 📱 QR Code Reader is a minimalist application with scan history and the ability to sort by date.
- 🛡️ Kaspersky QR Scanner
- 📸 Bixby Vision (if available) – uses Samsung’s engine, but can run on Xiaomi, offering excellent text translation with photos.
Installing third-party software is justified if you are working with logistics or warehouses where codes can be printed poorly. Standard Android tools in such cases often pass, requiring perfect contrast.
Why are third-party scanners faster?
Focusing Problems and Their Solutions
The Mi 8 Pro has a dual main camera, and sometimes the system can’t figure out which lens to use for macro photography code. If the image in the viewfinder “floats” or remains blurry, the problem lies in the drivers or contamination.
The first thing you do is wipe the camera module, and the fat spots on your fingers create a dissipation effect, and the autofocus can't catch on to the contrasting edges of the square, and use a soft microfiber to avoid the harsh chemicals.
If the physical cleanup didn't work, try resetting the camera app. Go to Settings → Apps → Camera → Memory → Clear the data. This will bring all zoom and focus settings back to factory values.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| The camera doesn't see the code close. | Minimum focus threshold down | Move your phone 10-15cm or use zoom |
| The scanner reacts slowly | Lack of RAM | Close the background applications through the task menu |
| Black screen in the scanner | Conflict of access rights | Check the permissions in the privacy settings |
| Code reads upside down | Gyroscope error | Calibrate the sensors through the engineering menu (#64663###) |
⚠️ If the camera stops focusing on anything (not just on the camera) QR), And you hear a quiet crackle from the module, maybe the autofocus drive has failed, and then the software won't help, you need repairs.
Safety issues in scanning
Use of the QR-Attackers can place a sticker in a public place with a malicious link on top of the legitimized code. Xiaomi Mi 8 Pro has built-in protection, but it is not all-powerful.
Never click on links if the scanner warns of potential danger. Also pay attention to the site address: instead of bank.ru, bank-en-security.com can open.
💡
Always check the domain name in the browser address bar immediately after scanning before entering any personal details or passwords.
It is recommended to disable automatic link clicking in the scanner settings if this option is available in your version of MIUI. It is better to see the address first, analyze it, and then click "Open." This will take a second, but will save your data.
