How to Scan on Xiaomi Android: The Complete Guide

Smartphones have long since ceased to be just a means of communication, becoming powerful mobile offices capable of solving problems of any complexity. Owners of Xiaomi devices often face the need to quickly translate a paper document into a digital format without resorting to the help of bulky MFPs. Scanning on Android has become so simple that it does not even require the installation of additional software, since the basic functionality of the MIUI or HyperOS system already includes the necessary tools.

In this article, we will discuss in detail all available ways to create digital copies of documents, photos and QR-You will learn about the hidden features of the system camera, the capabilities of the built-in Scanner application and the advantages of using third-party solutions for professional word processing. The quality of digitalization directly depends on the correct choice of method and setting the shooting parameters, which we will consider further.

There are several scenarios for using a scanner: from simple reading QR-code before creating a multi-page PDF-Understanding the differences between these methods will save you time and get the best quality in any situation.

Use of the built-in "Scanner" application

In the shell. MIUI And the new HyperOS has a system application that's called the Scanner, which is a universal tool that combines reading functions. QR-It's just a simple way to start, find an icon with the appropriate name in the Tools folder, or just swipe left on the desktop (if the widget is activated) and click on the camera icon.

The interface is as minimal as possible. At the bottom of the screen are tabs for different modes of operation. We're interested in the "Documents" tab. When you switch to this mode, the camera automatically determines the boundaries of the piece of paper, even if it's lying on the table at an angle. Automatic framing greatly speeds up the process, eliminating the need to manually align the image.

After pressing the shutter button, the system will suggest selecting a color filter. The options available are "Original", "Enhanced", "Black and White" and "Gray". For text documents, "Enhanced" or "Black and White" mode is best, as they increase the contrast of text, making it more readable on the screen.

⚠️ Note: When using the "Enhanced" mode, the algorithm may unnecessarily whiten the background, which can make the pale text invisible. Always check the result before saving.

The finished file can be saved in the gallery or sent directly through instant messengers. The application allows you to scan several pages in a row, creating a single file, which is extremely convenient for contracts or multi-page references.

💡

For better recognition of the boundaries of the document, place it on a contrasting background, such as a dark table for white paper.

Scanning through Xiaomi’s system camera

Many users are unaware that the standard Camera app on Xiaomi smartphones has a built-in document scanning mode, which allows you not to search for a separate application, but immediately get to work. To activate this feature, open the camera and select Documents from the lower menu of modes (sometimes this mode is hidden in the “More” section, if not displayed on the main screen).

The main advantage of using a system camera over third-party apps is the deep integration with the phone's hardware.The camera is better at focusing on small fonts and takes a snapshot faster, minimizing the risk of image lubrication due to hand shaking.

The process of shooting is almost identical to the work of a separate scanner application. You point the lens over the document, the system illuminates the boundaries in yellow or blue, and you take the picture. After that, the image is automatically processed: the perspective is aligned and color correction is applied.

It is important to note that some firmware versions may have different functionality. If you don't find Documents mode, try updating the Camera app through the GetApps store or Google Play. It's also worth checking the resolution settings, as in low-quality mode, text can be fuzzy.

Google Lens: The Power of Artificial Intelligence

Google Lens is integrated into most Android smartphones and is one of the most powerful text tools available. On Xiaomi, it is often available directly through the Google Search Bar widget or through the Google Photos app, with its advanced text recognition algorithm (OCR) and instant translation capabilities being a major advantage.

To scan a document, run Google Lens, hover your camera, and press Text. The system will highlight all the words you recognize. You can select a particular snippet or click "Select All," and then copy the text or save the image. This is ideal if you don't want a photo of the document, but editable text.

Google Lens is not limited to simple copying, you can:

• 📄 Send the scanned text directly to Google Docs, saving the formatting.
• 🌍 Translate text in the image instantly into any language supported by the translator.
• 🔍 Find information about the object that got into the frame, or the product in online stores.
• 📧 Recognise contact details (business cards) and immediately save them in the phone book.

Google Lens requires an internet connection for maximum speed, although basic features can work offline, and handwriting recognition is often better than standard scanners, thanks to Google’s powerful server algorithms.

Third-party applications for professionals

If Xiaomi and Google Lens are not enough, Google Play apps will come to the rescue, offering advanced document management, cloud sync, and finer image customization, with Adobe Scan, Microsoft Lens, and CamScanner leading the way.

Adobe Scan is great for those who already use the Adobe ecosystem. It automatically clears the background, removes shadows, and aligns the document. It also knows how to recognize text and save it to a searchable PDF.

Microsoft Lens is indispensable for office workers, it can scan boards and business cards, and it also has a unique feature of converting a table in a photo into an editable Excel file, which saves hours of manual reprinting.

It’s worth considering that many advanced features in free versions of such applications may be limited or accompanied by advertising, but for one-off tasks, their capabilities are usually more than enough.

Comparison of scanning methods

To make it easier for you to choose the right tool, we have prepared a basic method comparison table that will help you quickly navigate your current needs and quality requirements.

As you can see from the table, Xiaomi’s built-in tools are enough for everyday tasks, they provide a good balance between quality and speed, and specialized applications only make sense if you need to work with large volumes of documentation or specific formats.

⚠️ Note: When using third-party apps, carefully review the permissions they request.Some scanners may require access to geolocation or contacts without an obvious need.

Tips for Getting the Perfect Scan

Even the best algorithm can't make a good copy if the original conditions of the shooting are violated. Light is the main factor. Try to scan documents in bright but diffuse daylight. Direct sunlight creates hard shadows and glare that interfere with text recognition.

If there's no natural light, use artificial light, but make sure your phone doesn't obscure the light with its shadow. Keep your smartphone strictly parallel to the plane of the document. Although the software can align perspective, head-to-head shooting gives you the best sharpness over the entire area of the sheet.

To create multi-page PDF-The best way to use the batch shooting mode on Xiaomi is in the built-in scanner, you take pictures of the pages one by one, and the application combines them into one file.

Don't forget the resolution. Make sure you set the camera or scanner settings to the maximum resolution available. Text is important to keep letters clear. The optimal resolution for archiving documents is 300 dpi, which is about 2-3 MP for A4, but modern smartphones do it automatically.

💡

The main secret of a quality scan is not software, but good lighting and a clean smartphone camera.
