How to make a scan on Xiaomi: the complete guide

Xiaomi’s modern smartphones have evolved into powerful pocket offices capable of performing a variety of tasks that previously required bulky hardware, and one of the most sought-after features that device owners use on a daily basis is the ability to quickly scan objects. Whether it is an important document to send by email or QR-In-store payment code – built-in tools MIUI HyperOS and the new shell allow you to solve these problems in seconds without installing third-party software.

But many users still don’t know where the feature is hiding or confuse the different types of scans. In this article, we’ll take a look at how you can create digital copies on your device, and learn about the intricacies of a standard camera, specialized applications, and hidden security features that make life much easier.

We will not only look at the software part, but also touch on the issues of optimizing the quality of the images obtained. Proper settings before starting work will help to avoid blurred images and problems with text recognition. Understanding the principles of optical character recognition (OCR) based on Android will allow you to use the gadget as efficiently as possible.

Use of the standard Camera application

The most obvious and quickest way to scan Xiaomi is to use the camera app, which is the camera app, and the developers have built powerful image analysis algorithms directly into the viewfinder, so you don't have to search for individual icons or go to complex menus to scan. QR-You just run an application, and the system will analyze the content of the frame itself.

To activate scan mode, it is often enough to point the lens at the object. If automatic recognition does not work, pay attention to the top of the screen or the sidebar of the tools. There may be an icon for Documents or Text. Switching to this mode causes the camera to automatically align perspective and increase contrast, turning the photo into a full scan.

⚠️ Warning: When scanning important documents automatically, always check the angles of the frame.The camera may accidentally crop some text or leave extra fields if you do not hold the phone strictly parallel to the sheet.

The quality of the final file is directly dependent on lighting and hand stability. Try to avoid glare on the glossy surface of the paper, as these can be perceived by algorithms as part of the text, which will make it difficult to read later. For best results, use natural light or uniform artificial light from above.

💡

Use a tripod or elbow over a desk when scanning multi-page documents to keep a single perspective and lighting for all pages.

Working with the application Scanning documents

Xiaomi’s ecosystem has a separate system application, often called “Scanner” or “Documents,” that provides more advanced features than a conventional camera, and offers batch scanning, automatic sheet boundaries, and improved readability through filters.

You can run this tool and access different modes of operation. You can choose to scan your business cards, where the system will try to automatically recognize your name, phone and email, saving them to contacts. You can also use Table mode, which converts the table image to an editable Excel or CSV format.

After creating the scan, the system will prompt you to save the file in a specific format. PDF and JPG are usually available. For text documents, it is preferable to choose PDF, since this format better preserves the structure of the page and opens more easily on any computer without distorting the layout.

Importantly, the app allows you to do basic processing of the finished images, so if you took a picture of a document with a regular camera, you can import it into the Scanner to align and improve contrast, which saves the situation when you didn't have time to position accurately.

Scanning. QR-codes and barcodes

Special attention should be paid to the function of scanning barcodes and QR-In Xiaomi smartphones, this feature is often integrated into the control center or is available through long-term clicking on the camera icon. This allows you to instantly click on links, connect to Wi-Fi or pay for purchases without unlocking the phone completely.

The way the technology works is that the camera reads the graphic pattern and decodes the information encrypted in it. Depending on the type of code, the system will suggest an action. For links, go to the browser, for contacts, a suggestion to save to the phone book, for applications, go to the Google Play store or GetApps.

If a standard camera can't see the code, try using the built-in scanner in the Security app, which has a more sensitive recognition algorithm and can read corrupted or poorly printed codes that a regular camera ignores.

Be careful when scanning codes from unverified sources. QR-code leading to a phishing site, although the system MIUI It has built-in protection, always check the address of the site to which you are being redirected before entering personal data.

Set up a fingerprint scanner

When you talk about scanning on Xiaomi, you can also think about biometric security, because fingerprint scanners are a key element of protecting your data, and depending on the smartphone model, they can be located on the back, on the side in the power button, or even under the screen.

To set up, go to Settings → Passwords & Security → Unlock by fingerprint. The system will ask you to apply your finger to the sensor several times, changing the angle of inclination. This is necessary to create an accurate digital map of your finger, which ensures high speed and reliability of unlocking.

It is recommended to add fingerprints of both thumbs and index fingers if you often use the phone in different positions, which will significantly improve the usability of the device in everyday life, especially when one hand is occupied.

⚠️ Warning: If you have moisture, fat, or skin damage (cuts, calluses) on your fingers, the scanner may not work properly. In such cases, use an alternative unlocking method, such as a pattern lock or Face. ID.

The modern ultrasonic and optical scanners in Xiaomi’s flagship models work even with wet hands, but for budget models, sensor cleanliness remains critical.

Table of comparison of scanning methods

To make it easier for you to choose the right tool for a particular task, we have prepared a comparison table that shows the differences between a standard camera, a specialized application and third-party solutions.

As you can see from the table, the system's built-in tools are sufficient for everyday needs, but more specialized software with OCR (text recognition) may be needed to handle large volumes of paper archives.

Solving problems in scanning

Sometimes users are faced with the fact that the phone refuses to focus or recognize the object. Most often the problem lies in the contamination of the optics. Wipe the camera with a soft microfiber, as even subtle fatty traces can create a fog effect that interferes with autofocus.

Another common reason is a lack of RAM: If you have a lot of heavy applications open, the camera may be latent, close the background processes through the menu of running apps, and try to run the scan again.

If there are problems with recognition QR-If the codes are constantly appearing, check the permission settings for the camera app. Make sure it has access to storage and geolocation if necessary, as some codes require location confirmation to activate.

💡

Regular cleaning of the camera lens and updating of system software is the key to stable operation of all scanning functions on your Xiaomi.

In rare cases, you may need to reset your camera app settings, which can be done in the Apps → All Apps → Camera → Memory → Clean. This action will bring the camera settings back to factory settings without deleting your personal photos.
