How to scan the QR code with a Xiaomi Mi8 mobile phone

Owners of the Xiaomi Mi8 smartphone often face the need to quickly read two-dimensional barcodes to connect to Wi-Fi, pay for purchases or click on links. Despite the fact that the model is no longer a flagship, it fully supports modern image recognition standards thanks to its powerful hardware and current versions of the MIUI shell. The scanning process has become much easier in recent years, since it now does not require the installation of third-party applications from unverified sources.

The challenge for many users is finding the right feature in Android, which on Xiaomi devices has its own unique implementation features. The camera algorithms and Google system services built in allow you to instantly decode information encrypted in black and white square. You don't need to be an expert in mobile technology to master this skill in a few minutes.

In this article, we will take a closer look at all the ways you can read data on your device, and we will also look at the typical problems that come with optics. We will touch on security, focus settings, and the use of specialized utilities from the manufacturer. The integration of recognition systems into modern smartphones has reached a level that is almost invisible to the user.

Use of the built-in scanner function in the Camera app

The fastest and most obvious way to access content QR-Xiaomi code Mi8 — This is using a regular Camera app, and the company's engineers have built the recognition module directly into the shooting interface, so you don't have to run individual programs. To activate this function, it is enough to open the standard camera application and hover the lens over the image of the code.

If the scan is not automatic, you need to check the settings. The top menu of the camera interface often contains an icon in the form of a square or a special symbol of the scanner. Pressing it puts the camera in Mi Scan mode, which is optimized for reading barcodes of various formats. In some versions of the MIUI firmware, this mode is activated by long pressing on the viewfinder area.

⚠️ Note: Make sure that the Camera app is allowed to access geolocation and the Internet in the privacy settings, as some types of codes require network verification before opening a link.

Reading quality is directly dependent on the lighting and the purity of the lens. Wipe the camera with a soft cloth before trying to scan if the image appears blurred. The system automatically determines the boundaries of the code and the vibration signal will report the successful reading of the data.

For users who use this feature often, it will be useful to know that a fast access widget can be on a locked screen or in the control center menu. adding it will significantly speed up the process of interacting with the outside world. Autofocus on the Xiaomi Mi8 works quickly enough, but in poor light it is better to lock the phone with your hands.

💡

Keep your phone 10-15 centimeters away from the code for the best focus, as the macro mode on the Mi8 has a minimum focus distance.

Using Google Lens and Google Lens for Advanced Features

An alternative to the built-in scanner is Google Lens, which is deeply integrated into the Android operating system. On Xiaomi smartphones, this service is often called through the Google search bar widget or through the Google Photos app. It is a powerful tool that not only reads a link, but can translate text, recognize products or copy contact information.

To take advantage of this method, open the Google app on the home screen and click on the camera icon in the search bar. Once you run the Google Lens interface, hover the camera over the code. The system will analyze the image in real time and suggest available actions such as clicking on a URL, saving a contact or searching for product information.

The advantage of using Google services is their ability to handle complex or corrupted codes that a standard camera cannot read. Machine learning algorithms correct for perspective distortion and improve image contrast on the fly. This is especially true if the code is printed on crumpled paper or located on a curved surface.

• 📸 Allows you to translate text from images in real time.
• 🔍 Recognizes animal breeds, plants and attractions.
• 📋 Copies text from paper media to clipboard.
• 🛒 Finds products in online stores by photo.

Importantly, Google Lens requires a stable Internet connection to function, because image processing takes place on the company’s servers, but basic link reading can work offline if the data is encoded in simple text format, and intelligent content analysis makes this a preferred approach for complex tasks.

Working with Mi Scan and system utilities

In the Xiaomi ecosystem, there is a separate application called Mi Scan (or “Scanner”), which is part of the system tools, designed to work more deeply with code, including creating your own encryption and scanning documents, and you can find it in the Tools folder on your desktop or through a search system.

Mi Scan offers more flexible settings than a regular camera, where you can choose the type of scan you can scan manually: goods, documents, translations or code, and packet scanning is also available, where the phone reads several codes in a row without returning to the menu, which is useful for inventory or large amounts of data.

One of the key features of a system scanner is that you can generate code. QR-code for your business card, Wi-Fi network or text message and send it to another user. the application interface is intuitive and fully localized into Russian.

Using the Mi Scan system utility guarantees better compatibility with Xiaomi branded services such as Mi Pay or adding contacts to the Mi Cloud. If a standard camera fails, accessing this application often solves the problem. System optimization provides minimal power consumption when working.

Scanning codes through gallery and browser

Often, there is a situation where the image with the code is already stored in the memory of the phone, for example, came in a message or was downloaded from the Internet. In this case, you do not need to point the camera anywhere. Xiaomi Gallery is equipped with a built-in image analyzer that automatically recognizes the image. QR-photocode.

You just have to open the image in the Gallery app, and if there's code in the photo, there's a "Recognise" button or scanner icon at the bottom of the screen or in the "Three Dots" menu, and clicking on that button will trigger the decoding process without leaving the app, which is a convenient way to work with archived data.

Similar functionality is present in the Mi Browser browser and the popular Google Chrome. There is a scan button in the address bar or in the browser settings menu that allows you not only to use the camera, but also to download images from the file system. Image analytics works at the operating system level, so it is available in many applications.

⚠️ Be extremely careful when scanning codes from unknown sources in the gallery, as they can lead to phishing sites, even if you do not click on the link immediately.

Browsers also know how to preview a link before clicking, which adds a layer of security: you will see the full site address and be able to make a decision about the transition, which is critical to protecting personal data on the Xiaomi Mi8 device.

Set up security and check links before transitioning

Security when scanning codes is a priority, as attackers can encode malicious links. Mi8 The security system is built-in, which checks URL-Real-time addresses, but users must also be vigilant.

Before you click on a link, carefully examine the address. If instead of the expected site you see a set of random characters or a domain that does not match the brand, click on it. Google's Safe Browsing system, integrated into the shell, warns of dangerous sites with a red screen.

It is recommended to enable Real-Time Protection in the Security app, which not only checks the applications that are installed, but also the links that are opened through the system components, which creates an additional barrier to potential threats.

• 🛡️ Always check your domain name before entering passwords.
• 🔒 Do not allow websites to access contacts without needing to.
• 🚫 Ignore codes that promise “free money” or wins.
• 📲 Use antivirus databases to check for suspicious URL.

If you scan the code for payment, make sure that the connection is protected by HTTPS. The browser address bar should display the lock icon. Two-factor authentication in payment systems also serves as a reliable protection even in the event of a data breach.

Solving Focus and Image Quality Problems

Despite the Xiaomi Mi8’s high-quality optics, code-reading difficulties sometimes occur. The main cause is usually lens contamination or a failure in focusing software. Simply wiping the camera often solves 90% of the problems.

If the camera isn't focusing, try touching the area of the screen where the code is to force sharpness. In some cases, rebooting the camera app or the entire smartphone helps. The autofocus module may be affected by a temporary memory buffer overflow.

Also worth checking for system updates. Xiaomi engineers regularly release patches that improve image processing algorithms. Go to Settings → About Phone → System Update and check for new versions of MIUI.

⚠️ Warning: Do not use third-party apps to “improve focus” from unreliable sources, they may contain ad modules or viruses that will slow down your phone.

In rare cases, the problem can be hardware, such as damage to the camera module after a fall. If the software methods do not help and the camera does not focus on anything, you should contact the service center for diagnosis. Mi8 replaceable and does not require complex repairs.

💡

Regular cleaning of the lens and system updates are the main conditions for stable operation of the scanner on the Xiaomi Mi8.
