How to scan documents in the phone Xiaomi

Xiaomi’s modern smartphones have long since ceased to be a means of communication, becoming powerful pocket offices. One of the most popular tools for students and office workers is the ability to quickly convert paper text to digital format. Many users do not even realize that they do not need to download dubious programs from the Internet, since everything they need is already built into the shell of MIUI or the new HyperOS.

The scanning process on these devices is optimized and takes seconds to complete, and the built-in AI algorithms automatically define the boundaries of the sheet, align perspective, and remove shadows, making the document look like a quality copy made on a professional scanner, and this is especially true when there is no printer at hand and you need to send the contract or certificate right now.

In this article, we will take a look at all the available ways to create digital copies, from the standard Camera app to advanced system tools, learn how to customize quality, recognize text and even translate documents on the fly.

Use of the built-in Documents mode in the camera

The fastest and most obvious way to get a high-quality digital copy is to use a specialized mode in a standard application. Unlike regular photography, this mode is precisely for text work: it increases contrast, aligns the sheet and trims the extra edges of the background. To activate this feature, launch the Camera app and find the "More" button in the bottom menu.

In the additional modes that open, you need to select Documents. After switching, the interface changes: a frame will appear on the screen that automatically highlights the boundaries of a piece of paper. You can point the lens at the document so that it is inside this frame, and the system will take the picture at the moment of best focus. If the automation is not working correctly, you can manually press the shutter button.

It is important to note that Documents mode works best in good lighting.Try to avoid sharp shadows falling from the phone itself or hands, as algorithms may misdetect page boundaries. If you scan many pages in a row, the mode allows you to take serial pictures, after which they can be combined into one. PDF-file right in the gallery.

For better scanning quality, wipe the camera lens before shooting - greasy spots blur small letters and interfere with autofocus.

Scanning through the “Scanner” application

Most MIUI firmware has a separate system application called the Scanner, which offers more flexible settings than a regular camera, allowing you to not only take pictures, but also immediately process the result, and you can find it in the Tools folder on your desktop or through a global settings search.

The scanner interface is divided into several tabs, among which we are interested in Documents. There are three main modes of operation: photo, PDF and text recognition. When you choose a photo mode, you get a processed image, and PDF mode immediately forms a multi-page file, which is extremely convenient for contracts or passports. Processing occurs instantly after you press the down button.

One of the key features of this tool is that it can be batch-processed, you can scan a few pages, then you can select them all in the gallery, click "Create PDF" and you can get a finished document with a single name, and it can automatically improve the readability of text, making the background white and the letters black, which saves ink when you print it later.

• 📄 Documents Mode – Optimized for text clarity and color distortion removal.
• 📑 Packet scanning function – allows you to create multi-page files without unnecessary actions.
• 🔍 OCR-Recognition – extracts text from the image for copying to the clipboard.
• 🌐 Translator – built-in translation function of text from the picture in real time.

Customization of quality and preservation formats

The quality of the final file depends on the selected parameters in the application settings. By default, the system can save images in a compressed format to save space, which is not always acceptable for official papers. To change this, open the camera settings (three bars in the corner) and find the section responsible for the quality of the images or the format of the save.

For text documents, the best choice is the top quality JPG format or PDF if multi-page is required. PDF format is preferred for email, as it is guaranteed to open on any device without shifting the layout. Some phone models allow you to choose the resolution of the image, where you prefer the maximum values available to the matrix.

⚠️ Warning: When scanning small-print documents (receipts, checks) avoid digital zoom. It is better to come closer physically, as the software zoom dramatically reduces the clarity of the edges of letters.

You also have to look at color filters that are automatically used, and you can usually use Original, Increase Contrast, and Black and White modes, and you can use the original or light contrast for archiving, and you can use black and white for printing, which makes the text as readable as possible, and you can use these settings post-factum in the gallery editor.

Text Recognition and Translation (OCR)

Optical Character Recognition (OCR) technology is turning your phone into a powerful tool for working with information. Xiaomi's built-in algorithms are able to recognize text not only in Russian and English, but also in many other languages, which allows you not only to save a picture, but also copy text from it for insertion into the messenger or notes.

To use this feature, scan the document in the usual way, then open the resulting photo in the gallery. Click on the "More" button and select "Unlock text" (or "copy text"). The system will analyze the image, highlight the text blocks and prompt to copy their contents. Accuracy of recognition depends on the clarity of the original image and font.

The translation feature deserves special attention. The Scanner app has a Translation mode that superimposes the translation of foreign text directly on top of the original in augmented reality. It is an indispensable tool when working with instructions or menus in foreign languages. You can take a picture of the page, and the phone will replace foreign words with Russian, retaining the formatting.

Work on multi-page documents

When you need to scan a 10-page or 20-page contract, it's important to do it correctly so you don't get confused. The Scanner app has a special mode that allows you to shoot continuously. Once activated, just flip through the pages, and the phone will take pictures or wait for your signal, saving them in a single session.

Once you've finished shooting, all images are automatically combined into a single PDF file, so you can reorder pages, delete defective images, or add new pages to a document you've already created, much more convenient than sending twenty separate images to the recipient in the messenger, which are often lost in the message stream.

When you save a multi-page document, the system will prompt you to specify the file name and folder to save. It is recommended to give files clear names, such as “Arrange 2026”, so that they can be easily found through search. Files are saved in the system folder “MIUI Scanner” or “Scan”, accessible through the file manager.

Third-party alternatives and Google lens

Despite the wide capabilities of the built-in tools, sometimes you need functionality that goes beyond the MIUI standards. In such cases, the Google Lens, which is integrated into the Android system, is available through the Google search widget or directly from the camera interface, if the appropriate option is enabled.

Google Lens has more advanced machine learning algorithms, which allows it to better handle handwriting and complex table formatting. It is also closely linked to Google services, allowing you to instantly send scanned text to Google Docs or save contacts directly to the phone book. For users of the Google ecosystem, this is often a primary tool.

There are specialized applications from GetApps or Play Market, such as Adobe Scan or Microsoft Lens, which offer cloud storage, automatic sorting and advanced editing capabilities, but it is worth remembering that installing unnecessary applications consumes battery power and takes up space in memory, so you should only use them if the built-in functionality is really not enough.

⚠️ Note: Third-party applications often require access to your photos and geolocations. carefully read permissions before installation, so as not to share personal data with third parties.
