Where's the Xiaomi scanner? QR-Code: Complete Guide

Modern Xiaomi, Redmi and POCO smartphones have become universal tools for everyday tasks, and one of the most sought-after features is reading two-dimensional barcodes. Users often face a situation where you need to quickly scan the code for payment, Wi-Fi connection or clicking on a link, but the standard scanner icon is not obvious. In the shell of MIUI and the new HyperOS, the logic of the location of tools can change, which raises questions among device owners.

In this article, we will analyze in detail all possible places where the scanner is located in Xiaomi. QR-We'll explain how to activate this feature if it's hidden by default, and you'll learn about the built-in features of the system that don't require additional software, as well as the intricacies of working with the Mi Scan and the system camera. Understanding these nuances will save you time and allow you to effectively use the potential of your gadget.

We’ll look at different use cases, from simple link scanning to complex document handling through Documents mode, and we’ll also cover security and explain why embedded tools are often more reliable than third-party counterparts from the Play Market. If you’re looking for a quick way to activate the scan, this guide will be your main guide.

Built-in scanner in the Camera app

The fastest and most obvious way to find a scanner is to use the standard Camera app. Xiaomi engineers built in recognition algorithms QR-The system can be used to read the code directly to the viewfinder, which allows you to read information without switching between applications. However, this feature is not always active out of the box and may require manual inclusion in settings.

To activate the scan, open the Camera app and click on the three horizontal bars at the top of the screen. QR-Make sure the switch is opposite the Scan function. QR-The codes are put into active position, and then when you point the lens at the code, the system automatically suggests the action.

⚠️ Note: In some versions of the shell MIUI This feature can be called Google Lens or Lens. If the standard scanner is not working, check if the camera is blocked from accessing the Internet, as some codes require a connection to the server to recognize.

Importantly, the viewfinder algorithms vary depending on the firmware version. On older devices with MIUI 11 or 12, the interface may be different from current versions of HyperOS. If you can't see the switch, try updating the Camera app through the GetApps store or Google Play.

For users who use this feature often, it will be useful to know that the widget exists. It can be brought to the desktop for instant access. Just press the empty space on the screen, select the Widgets and find the Scanner. This will create a separate icon that immediately starts the scan mode, bypassing unnecessary steps.

• 📷 Open the Camera app and check the top corner of the screen for the scanner icon.
• ⚙️ Go to the camera settings and activate the slider "Scan" QR-code".
• 🔍 Point the lens on the code - recognition occurs automatically without pressing buttons.
• 🚀 Use a desktop widget to instantly start the scan feature.

💡

If the camera is focusing but not reading the code, try changing the distance to the object or wipe the lens — greasy spots often interfere with recognition algorithms.

System application Scanner (Mi Scan)

Special attention should be paid to the system application Scanner (or Mi Scan), which is pre-installed on Xiaomi devices. Unlike the camera, this tool is sharpened specifically for working with codes and documents, offering deeper functionality, you can find it in the Tools folder on the desktop or through a search system.

The app supports many modes of operation, beyond just reading links, it can translate text in real time, recognize products in stores and even scan documents to create a new text. PDF-And that makes it an indispensable tool not only for entertainment, but also for work.

The application interface is divided into several tabs. The main tab is responsible for the standard tabs. QR-By switching to the Documents tab, you can scan multi-page text, which the system automatically aligns and improves with contrast, which is especially useful for students and office workers.

One of the key features of the Mi Scan is that you can scan the codes from the images in the gallery, and if you've been sent a screenshot of the code in the messenger, you don't have to go anywhere. Just open the image, click "More" and select "Recognize" QR-code" or use the "Import from the gallery" function inside the scanner itself.

• 📄 Documents mode allows you to create digital copies of papers with improved quality.
• 🛍️ The function "Goods" helps to find information about the product by its barcode in stores.
• 🌐 The translator works in real time, overlaying text over the image through the camera.
• 🖼️ Ability to download code from the gallery to analyze static images.

Scan through Control Center and Lock screen

With the new MIUI 13, MIUI 14 and HyperOS, Xiaomi has introduced even faster ways to access the scanner. Now you don't even have to unlock the phone completely to read the code. This is implemented through the Control Center and the Lock screen, which greatly speeds up the process.

Control Center often has a separate scanner button, and if you can't see it in the shortcuts, click on the edit button (usually a pencil icon or a square with a minus) and drag the scanner icon into the active zone, which will allow you to start the scan with one touch in one click.

The lock screen can also offer quick access. When a recognized code notification appears or if you press the camera icon for a long time (depending on the software version), a context menu may appear. In some firmware regions, the Scan with the screen off function works with double tapping, but this requires support from the sensors.

⚠️ Attention: The scanner in the control center may not work if the Security or Scanner app has been revoked for camera use. Check the privacy settings if the button is not responsive.

For maximum efficiency, it is recommended to adjust shortcuts to your habits. If you rarely pay through NFC, but often scan codes, replacing the payment button with a scanner in the curtain will be a logical solution.

• 📲 Add the “Scanner” label to the notification curtain via the editing menu.
• 🔒 Check the lock screen settings for quick action.
• ⚡ Use double-touch (if supported) for quick start-up.
• 🔧 Set shortcuts according to the frequency of use of functions.

Comparison of scanning methods in MIUI and HyperOS

With the release of the new HyperOS shell, the approach to system applications has changed, with many features being merged or renamed, which can confuse users who have migrated from older versions of MIUI. Understanding the differences will help them navigate the interface faster.

In classic MIUI, the scanner was often a separate application with its own interface. HyperOS tends to integrate scanning features directly into system services, such as a search engine or a search widget, making the process more seamless, but less noticeable for those looking for a separate icon.

Below is a table comparing the main features of the available scanning methods on Xiaomi devices:

The choice of method depends on your current tasks. For quick payment in the store, a widget or camera is ideal. If you need to scan a complex document or translate a sign in a foreign language, you should use a full-fledged Mi Scan or Google Lens application.

💡

HyperOS combines scanner features with global search, making an individual application less visible but more integrated into the system.

Problems with recognition and their solution

Even on powerful Xiaomi smartphones, there are times when the camera sees the code but doesn't read it, which can be due to software failures, optical contamination, or incorrect resolution settings. Let's look at the main causes and ways to fix them.

A common problem is lack of focus. In manual camera mode (Profi), autofocus can be turned off. Make sure you're in Photo or Video mode, where autofocus is active by default. Also try tapping your finger on the screen in the area of the code to force the lens to focus.

Another common reason is low screen brightness if you're scanning code from another device, or poor indoor lighting. Computer vision algorithms require clear contrasting boundaries between black and white code modules. Noise on the matrix when there's not enough light interferes with decoding.

⚠️ Note: If the scanner stopped working after the system update, try clearing the Camera and Scanner app cache through the Settings menu → Annexes → Application management. Don't delete data, just cache.

In rare cases, the problem is a damaged camera module or software conflict with installed filters. If nothing helps, resetting the camera settings to factory values often solves the problem of software glitches.

• 🧹 Wipe the camera with a soft cloth – fingerprints scatter light.
• ☀️ Increase the lighting or brightness of the source code screen.
• 🔄 Reset the settings of the Camera application through the settings menu.
• 📱 Make sure the code is not corrupted and has clear boundaries.

Safety in scanning QR-code

Use of the QR-Not only is code convenient, but it also carries security risks. Attackers can create codes that lead to phishing sites or run hidden downloads of malware. Xiaomi's built-in protections usually warn of danger, but vigilance cannot be lost.

Google Play Protect and MIUI antivirus modules check links received through the scanner before you click, and if the system flags a site as dangerous (red warning screen), do not ignore this message or click on the link.

Special care should be taken when scanning codes from unverified sources: street ads, letters from unknown senders. Instead of direct payment or data entry, it is better to first go to the official website of the organization and find the necessary information there.

The built-in Xiaomi scanner has a function of previewing the link. URL-Look carefully at the domain name: instead of sberbank.ru, it might say sber-bank-security.com.

• 🛡️ Always check. URL before the scan, even if the scanner is not.
• 🚫 Do not scan codes sent by unknown contacts in messengers.
• 🔒 Use two-factor authentication for all important services.
• 📲 Keep your antivirus databases MIUI Security up to date.

💡

The main rule of security: scanner is only a reading tool, it does not guarantee the security of the content on which the code leads.
