Scanner in Xiaomi phone: how to use built-in tools

Smartphones are no longer just a means of communication, becoming universal tools for solving everyday tasks. Owners of Xiaomi, Redmi and Poco devices often do not even realize that they have a powerful visual information analyzer in their pocket, capable of reading codes, translating text and identifying goods. Built-in scanner, integrated into the standard camera application and the system shell MIUI or HyperOS, allows you to instantly access sites, contacts and payment data without installing third-party software.

Using the system's regular tools is preferable to third-party applications for security and performance reasons. You don't have to look in the app store for questionable programs that may ask for unnecessary permissions or show intrusive advertising. QR-The codes operate at the operating system kernel level, providing instant response and high recognition accuracy even in poor lighting or damaged image.

In this guide, we will take a closer look at all the ways to activate and customize a scanner, explore the hidden possibilities of object recognition, and learn how to use the camera as a real-time translator, and understand the intricacies of this module will significantly accelerate interaction with the surrounding digital world.

Activation of the scanner through the Camera application

The fastest and most obvious way to start scanning is to use the standard Camera app. Unlike many other manufacturers, Xiaomi has integrated code recognition directly into the viewfinder. To get started, you just unlock your smartphone and launch the camera app. At the top of the screen, usually on the right or center, you'll see an icon that looks like a square with dots inside or says "QR."

Once you click on this icon, the camera goes into a special scan mode. QR-The system automatically determines the type of content and will suggest the appropriate action: open a link, add a contact, show the product in the online store or translate the text. It is important to note that this feature may require an active internet connection to function properly, especially if it is an object recognition or translator.

⚠️ Warning: When scanning codes from unknown sources, be extremely careful. QR-Phishing codes, masking malicious links as harmless images. URL-pre-transfer address.

If the scanner icon is not available as standard, it may be hidden in the mode menu. Swipe your finger down the lower panel of the shooting modes left or right to find the Scanner or Google Lens. Some versions of MIUI firmware may have different settings, so it's worth checking the additional menus.

Use of a separate Mi Scanner application

Most Xiaomi and Redmi smartphones have a separate system application called the Scanner (or Mi Scanner), which has advanced functionality compared to the basic camera mode and allows you to work with an archive of images, you can find it in the Tools folder on your desktop or through a search system.

When you start the app, you'll see an interface with multiple tabs or mode switching buttons. QR-It's also a special feature for documents, translations and purchases, and the key feature of this app is that it can download a code image from a gallery, which is very convenient if the code is sent in a messenger or saved as a screenshot.

To scan from the gallery, perform the following steps:

• 📸 Open the Scanner app and click on the gallery icon in the bottom corner.
• 🖼️ Select a previously saved image with a code or document.
• 🔍 The system will automatically analyze the picture and give the result.

The app also supports batch scanning and query history, allowing you to go back to previously scanned data, which is especially useful when working with documents or hardware serial numbers.

Recognition modes: Documents, Text and Translation

The scanner features in Xiaomi phones go beyond reading square codes. With the introduction of machine learning, the camera can recognize plain text, tables, and even handwritten notes. By switching to Documents or Text mode, you can scan a book page, contract, or extract.

Once scanned, the system will suggest saving the result in a variety of formats, so you can export the text to PDF, copy it to the clipboard, or send it directly to the note-taking app. When scanning the tables, the app will try to preserve the cell structure, eliminating the need to manually reprint the data in Excel.

Translation is real-time, and if you point the camera at a foreign language, you'll see a translation overlaid on top of the image, which is an indispensable feature for tourists or when learning the instructions for technology, dozens of languages are supported, including Chinese, English, German and Spanish.

Setup and permission to access the camera

If the scanner has stopped working or gives an access error, the problem most often lies in the privacy settings. Android OS strictly controls the access of applications to the camera.

Go to Settings → Apps → All apps. Go to Scanner or Camera. Select App Permissions and make sure you have permission to access the camera. It’s also worth checking gallery access if you plan to scan images from your phone’s memory.

Sometimes the malfunctions are due to a crowded cache, and cleaning the application data can make it work again:

• 🗑️ Go to the properties of the application "Scanner" through the settings.
• 🧹 Click “Clean” and select “Clear Cache».
• 🔄 Restart the device and check the function.

💡

For better text recognition in poor light, turn on a flash in the scanner interface, which will remove shadows and increase character contrast.

Scanning objects and searching for analogues

One of the most impressive features is the Buy mode or the Lens mode, where by pointing the camera at any item — sneakers, books, clothing items or appliances — the system will analyze the image and find similar products on the Internet, through integration with search engines and marketplaces.

This feature is useful not only for shopping, but also for identifying unknown objects, such as a rare plant or a piece of machinery, the camera will identify the object and provide a brief reference, the accuracy of recognition depends on the quality of the image and the uniqueness of the object.

This capability requires a stable network connection, and AI algorithms process images in the cloud, so if the signal is weak, the process can take longer or end in error.

Solving Recognition Problems and Errors

Despite the advanced algorithms, users may face difficulties: the camera may not focus, shudder or simply not see the code. Often the reason is trivial - contamination of the camera's protective glass.

Another common problem is glare on the glossy surface of the code. Try changing the angle of the phone relative to the scan plane. Avoid direct hitting of bright light into the lens, as this "lights up" the matrix.

⚠️ Note: If the scanner is slow or crashes constantly, check for updates for the Camera and Scanner app in the GetApps store or Google Play. Outdated versions may contain compatibility errors.

In rare cases, resetting the camera to factory settings helps, bringing all focus and image processing parameters back to their original state, killing possible software conflicts.
