You only need to correctly activate the desired switches in the settings or add a widget to the desktop.

Functionality of the built-in MIUI scanner

Before you start setting up, it’s important to understand what Xiaomi’s ecosystem offers to users: the built-in scanner is not just a barcode reader, but a comprehensive image-reading tool; it can recognize text, translate labels, copy Wi-Fi data, and even identify products in stores; intelligent recognition relies on neural networks built into smartphone processors.

The main advantage is that it's very integrated with the system, so you don't have to open a separate application, wait for it to load, and then point the camera, and it's available from almost anywhere in the interface, which saves time. And Mi AI algorithms allow you to automatically define the boundaries of a document and improve readability, removing shadows and leveling perspective.

• 📄 Scanning documents: creating clear PDF-files with automatic cropping of fields and improving text contrast.
• 🌐 Translator: Instant translation of text from a photo into any supported language, while saving formatting.
• 🛒 Product search: object recognition and search for analogues in online stores by image.
• 📶 Connecting to Wi-Fi: Reading QR-codes for automatic password entry and network connection.

⚠️ Note: Translation and recognition of complex objects may require an active Internet connection, as some of the calculations are performed on cloud servers.

Users often underestimate the capabilities of this tool by continuing to use third-party ad apps.The system solution is devoid of intrusive banners and has access to camera hardware acceleration, which allows for faster processing speeds.The Redmi Note and older models cope with the task almost instantly.

Activation through the settings of the Camera application

The easiest and most obvious way to turn on the scanner is to activate the appropriate mode in the standard Camera application. However, in many regions and firmware versions, this mode is hidden by default or replaced with Documents mode. To access the full functionality, you need to check the settings of the application itself.

Open the Camera app and swipe your finger down the lower mode bar to the right or left to find "More" or "More." In the menu that opens, you can often find a Scanner or Google Lens switch. If you only see Documents mode, then the full Mi Scanner scanner is not activated as the primary tool.

In some cases, it is necessary to manually enable the display QR-Go to the camera settings (three-lane icon or gears in the corner) and find the section related to code recognition. QR-The codes are in the active position, so that the camera can automatically focus on the codes and suggest actions when they are detected.

If the camera menu doesn't explicitly mention the document scanner, try switching to Photo mode and getting stuck the lens over text or code. In the upper right corner, you may see a T-square icon or a magnifier, and tapping it activates smart scanning mode. On Redmi K models and flagships, this process happens automatically thanks to the ISP chip.

Use of widgets and desktop shortcuts

For those who need to use the scanner frequently, the best solution is to display the function on the desktop. The MIUI shell allows you to create shortcuts for specific actions, avoiding the need to open applications. This is especially convenient when you need to urgently read code from a computer screen or paper media.

Solving common problems and errors

Despite the stability of the work, users can face problems: the scanner does not see the codes, the camera focuses on the background or the application closes. Often the cause lies in the contamination of the lens or the wrong distance to the object.

If the scanner has stopped responding to QR-In the privacy settings, make sure that Scanner and Camera have access to storage (to save photos) and geolocation (to maps.

• 📸 Fuzzy image: Remove the protective glass or case if they overlap part of the lens or create glare.
• 🔦 Poor lighting: Turn on the flash in scanner mode or use an external light source to illuminate the document.
• 🔄 Hang: Force the application to close through the menu of running tasks and open it again.
• 📉 Low performance: Close background apps if scanning is slow on older Redmi models.

In rare cases, resetting the camera to factory settings helps. In the camera settings menu, find the "Restore Default Settings" button, which returns all focus and exposure settings to their original state, which often eliminates software failures of the image processing module.

If the problem persists after all the manipulations, it may be a hardware malfunction of the camera module, in which case it is worth checking the camera in other modes, if ordinary photos are also blurred or have artifacts, you will need a diagnosis in the service center.
