How to turn on the scanner on the phone Xiaomi Redmi

Modern smartphones Xiaomi Redmi has long ceased to be just a means of communication, becoming a universal tool for working with information. the built-in camera of the device is able to recognize text, translate inscriptions in real time and read QR-codes without the need to install additional software, but many users do not even realize that the scanner is already integrated into the system and waiting for activation.

The scanning functionality on the MIUI shell or the new HyperOS is deeply implemented and can be triggered in a variety of ways depending on the specific model and firmware version. You don't have to search for complex engineering menus or download dubious applications from the Internet to digitize an important document. You just need to know where the necessary switches are hidden in the interface.

In this article, we will discuss in detail all available methods of activating the scanner, from standard system tools to advanced settings for professional text work. You will learn to instantly translate signs, copy text from photos and save documents to PDF directly from the camera menu.

Built-in scanner in the Camera app

The most obvious and quick way to start scanning is to use the standard Camera app, which is pre-installed on every Xiaomi Redmi device, and the company's engineers have implemented a powerful pattern recognition algorithm directly into the viewfinder, allowing the image to be processed before the image is created.

Open the camera app and look at the top of the screen or the sidebar, where the extra features are usually located. Depending on the version of the MIUI shell, you may need to click on the "More" icon or swipe to the right to see Documents or Scanner mode, which is where the basic paper-based functionality lies.

Once the appropriate mode is selected, the camera automatically determines the boundaries of the piece of paper or the code on the screen. The system itself aligns the perspective and improves the readability of the text by removing shadows and glare. This is especially useful when shooting in poor light, when a normal photo can be blurred or dark.

⚠️ Note: In some regions or on global firmware versions, the Scanner mode may be replaced by Google Lens. This is not a bug, but a licensing feature that we will discuss in the next sections of the article.

The quality of recognition depends on the cleanliness of the lens and the stability of the hands during the shooting. Try to keep the phone parallel to the plane of the document to avoid distortion of the geometry of the text. If the automatic alignment works incorrectly, many models allow you to manually adjust the angles of the document after shooting in the gallery.

💡

Wipe your camera with a soft cloth before scanning important documents – even microscopic stains of fat can reduce the accuracy of text recognition by artificial intelligence algorithms.

Use of the Mi Scanner application

Most of the brand's devices have a separate system application called the Mi Scanner, which is an advanced version of the camera feature specifically designed to work with codes and documents, and can be found in the Tools folder on your desktop or search the system.

The interface of this application is divided into several tabs, each of which is responsible for its own type of recognition. QR-This segmentation allows algorithms to apply the most appropriate image filters for each case.

One of the key features of the Mi Scanner is that it can be batch-processed, so you can scan a multi-page contract, and the application automatically collects all the pages into one. PDF-This eliminates the need to use third-party converters or send dozens of individual photos.

• 📄 Documents: Mode for scanning text files with improved contrast and edge alignment.
• 🛒 Products: Reads product barcodes to search for information online or in stores.
• 🌐 Translation: instant translation of the text overlaid with the camera.
• 🏠 Wi-Fi: Reads QR-code from a router or other phone to automatically connect to the network.

The app also keeps a scan history, which can be both convenient and potentially insecure.If you've scanned sensitive documents or personal access codes, be sure to clear the history in the app's settings so that unauthorized individuals don't get access to that information when the screen is unlocked.

Google Lens: Alternative for Global Versions

Global versions of Xiaomi firmware often feature a Chinese native scanner replaced by Google Lens, a powerful AI tool that is integrated not only into the camera app, but also into the Google Assistant and Google Photos app. Google Lens often outperforms standard handwriting recognition accuracy solutions.

To activate scanning through this service, just open the Camera app and find the lens icon (usually in the bottom corner or in the modes menu). After clicking, Google Lens will launch, which will prompt you to choose a category: text, pets, plants or purchases. The system works in real time, overlaying interactive elements directly on top of the image from the camera.

The feature that you're looking at is copying text from an image, and you can point the camera at a book, an article, or an ad, and you can pinpoint the area with your finger and click "Copy Text," and then you can put it in the clipboard and you can paste it into any other application, like a messenger or a text editor.

⚠️ Note: Google Lens requires an active Internet connection and authorization in a Google account to function properly; without a network, the functionality will be severely limited or unavailable at all.

Another unique feature is object and plant recognition, where you can point a camera at a flower and get information about its appearance and care, and when you point at a purebred animal, the system will tell you the breed, and when you point at a landmark, it will tell you the history of the place, and this turns the smartphone into a pocket guide.

Scanning through the notification curtain and widgets

For those who need to scan codes or documents as quickly as possible, there is a way to activate through the control panel, setting up a quick access allows you to call the scanner with a single touch, bypass the search for an icon on your desktop, and this is especially true in situations where you need to quickly show a pass, a ticket or pay for a purchase in a store.

To add a scanner to the curtain, unlock the phone and swipe down from the top edge of the screen to open the control center. Find the edit button (usually a pencil icon or three dots in the corner) and in the list of available widgets, look for the scanner element or QR-Drag it to the Quick Settings Active Zone.

Once you add the widget, it takes literally a second to scan, and you just have to unblock the screen, swipe down and click on the scanner icon, and the camera will start right away in code-reading mode, ignoring other shooting modes, and this saves time and battery life because heavy photo processing algorithms don't load.

Some Redmi models allow you to set the scanner to run for a long press of the power button or double tap on the back cover (Quick Ball function or special gestures). Check the Settings section → Additional functions → Buttons to see if your device supports such customization capabilities.

💡

Adding a scanner to the notification curtain is the most effective way to reduce the time to access the feature in everyday use.

Setting up text recognition and translator

Xiaomi’s scanner features go beyond just saving a picture; its built-in OCR algorithms allow you to convert an image into editable text, an indispensable tool for students copying lectures or office workers working with paper archives.

When you scan a document in Text or Document mode, you see a "Recognize Text" or "T" button after you shoot it. The system will analyze the image and highlight the text blocks, you can copy the entire text or select specific paragraphs, and the accuracy of Russian and English recognition is very high.

The translator mode deserves special attention. When activated, the camera works in real time: you point the lens at a foreign sign or menu in a restaurant, and the translation appears on the screen over the original text, and this happens instantly, without having to take a picture and wait for processing.

• 📝 Copying: extracting text from an image for insertion into notes or messengers.
• 🌍 Translation: Support for dozens of languages while maintaining the original formatting.
• 🔍 Search: the ability to find information on the Internet about the text that is visible through the camera.
• 📞 Contacts: Automatic creation of contact card when scanning a business card.

It is important to note that the translator and the complex handwriting recognition functions require a network connection. Local language databases take up too much space, so the processing of the request often takes place on the servers of the service provider (Google or Xiaomi Cloud).

Solving and setting permissions

Despite the system’s fine-tuning, users may encounter situations where the scanner fails to start or issues an error. Most often, the problem lies in the lack of the necessary permissions for the application. Android strictly controls access to the camera and storage, so when you update the system or reset your settings, access could be revoked.

To check, go to Settings → Apps → All apps. Search for Scanner, Camera or Google (depending on the method used). Go to Application Permits and make sure that Camera and Memory are allowed. Without memory, scanned documents cannot be saved.

Another common cause of failure is an overcrowded app cache, which over time can conflict with new versions of recognition algorithms, and cleaning the cache through the application management menu often solves the problem of the scanner interface freezing or incorrect focus.

⚠️ Note: When cleaning the scanner application data (not to be confused with cache), your scan history and saved settings may be deleted. Use this option only if cleaning the cache has not helped.

If the camera is focused but not reading QR-If you have a macro lens, or a core module, you can try to change the distance to the object. If you have one, too close, you can defocus the macro lens or the main module. Also make sure that the lens doesn't have a protective film that can create glare that can interfere with the reading of the matrix of code.

💡

If the standard scanner does not see a certain QR-If you try to take a normal picture, open it in the Gallery, and click Google Lens or Recognize, static images are sometimes better processed by algorithms than the stream from the camera.

Use of third-party applications from the Play Market

When Xiaomi’s built-in functionality is not enough, you can always turn to third-party developers. Google Play offers hundreds of specialized applications that can provide advanced features such as Excel table recognition, batch file renaming or integration with cloud services like Dropbox and OneDrive.

Popular applications like Adobe Scan or Microsoft Lens offer professional document processing, which can automatically detect the edges of a business card or A4 sheet even against a motley background, remove the fingers holding a document, and align the color of the paper to the perfect white, which is critical for creating presentations or formal queries.

But security is a good thing to remember: scanners often request access to your entire gallery and camera, installing a little-known app puts you at risk of passing your personal data to third parties, and always check ratings, reviews, and installations before trusting the app to access your camera.

• 🛡️ Security: Use only proven apps with millions of installations.
• ☁️ Sync: Many scanners offer self-save to the cloud, which is convenient but requires an account.
• 📄 Formats: Third-party applications often support more output formats (Word, Excel, PowerPoint).

For most household tasks, Redmi's built-in tools are more than enough: they run faster, don't require additional software, don't consume battery in the background, and only make sense for specific professional tasks that require complex post-processing.
