How to scan documents from Xiaomi phone

Smartphones are no longer just communication devices, but powerful pocket offices that can handle complex work tasks. Xiaomi owners often wonder how to quickly and efficiently digitalize a paper document without using bulky office scanners. Fortunately, MIUI and its current HyperOS shell already have powerful text recognition and scanning tools built in.

You don’t have to search for and install heavy third-party apps if your goal is simply to keep a copy of your passport, contract, or check.The system offers native solutions that run faster and consume less battery life than the generic counterparts from the Play Market Store. However, if you need advanced functionality such as batch scanning or advanced editing, there’s always the option of connecting third-party software.

In this article, we will take a look at all the available ways to digitize papers, from the standard “Conductor” to the hidden features of the camera, you will learn how to adjust the image quality, remove shadows and automatically align the boundaries of the document for the perfect result.

Use of the built-in Scanner application

The easiest and fastest way to get a quality copy of a document is to use the system application that is pre-installed on every Xiaomi smartphone, which is located in the Tools folder, called the Scanner, QR-codes and documents, providing optimal contrast and clarity.

To get started, launch the app and select Documents mode in the bottom menu or hover the camera directly over a piece of paper. The system automatically determines the boundaries of the document, which will save you from having to manually fram the image. After pressing the shutter button, the program will suggest using filters to improve text readability, such as “Increased contrast” or “Black and white”.

Importantly, the app allows you to scan multi-page documents by merging them into a single PDF file. You can add pages sequentially, turning over sheets, and only after you finish a series of pictures save the final file, which is especially useful when working with contracts, passports or methodologies.

☑️ Checklist of quality scanning

Done: 0 / 4

You can send the finished document directly through instant messengers, save it to the Mi Cloud or Google Drive cloud storage, and print it if you have a printer connected. In the application settings, you can select the resolution of the stored images, which is critical if you need to send the file to print at the printing house.

⚠️ Attention: When scanning important documents (passport, TIN, diploma), be sure to check the final file for glare that can make part of the text unreadable. Automatic filters do not always cope with the glossy surface of laminated documents.

Scanning through the standard Camera app

Many users do not even suspect that the standard Camera app in Xiaomi smartphones has a built-in document recognition mode. You do not need to go to the menu and look for individual utilities - just open the camera and switch to “More”, where often there is a “Documents” or “Text” item.

In the newer versions of the HyperOS shell and the latest MIUI updates, the scan feature is integrated directly into the main mode of shooting through artificial intelligence. When you hover the lens over the text, an icon "T" or "Document" may appear in the corner of the screen, signaling that the system is ready to optimize the picture.

The main advantage of this method is speed. You don't have to wait for a single application to load. However, the functionality here can be limited to basic saving in JPEG, without the ability to immediately collect a multi-page PDF. For one-time shots of checks or business cards, this option is ideal.

Hidden opportunities AI-camera
In some Xiaomi models (especially the flagship series), the camera can not only scan, but also translate text in real time. To do this, in camera mode, you need to select the Translation function, hover over the text, and the system will replace foreign words in Russian directly on the screen before shooting.

If a standard camera doesn’t see a document automatically, try using Pro or Photo mode, but keep your phone strictly parallel to the table surface. Any deviation of the angle will result in geometric distortions that will then have to be manually corrected in the editor.

Application of Google Lens and Google Photos

Google’s ecosystem offers some of the most advanced image processing algorithms available on any Android smartphone, including Xiaomi. Google Lens is often already built into the Photos app or called through a search bar widget. It’s a powerful text tool.

To scan a document, open the Google Photos app, select a document shot, or click the scan button in the interface. The system will offer the option "Document Scanner" or "Copy Text." Google's algorithms do a great job of aligning perspective, even if you've taken a photo of a sheet at an angle.

The key to this method is not just to save a picture, but also to recognize text with high accuracy. You can copy the scanned text into the clipboard and paste it into Word or notes. Google Photos automatically saves scanned documents to the cloud, freeing up the phone's memory.

Google is especially useful if you need to translate a paper document into an editable text format, and the accuracy of recognizing Russian and English characters here is often higher than that of standard Chinese utilities.

💡

For best results when using Google Lens, try to photograph a document in daylight. Artificial yellow lighting of the lamp can reduce the accuracy of text recognition and distort colors.

Third-party applications for professional scanning

If you don't have enough built-in tools, Google Play offers a variety of customized applications, led by Adobe Scan, CamScanner, and Microsoft Lens, which provide advanced image processing tools that can be useful to students and office workers.

The main advantage of third-party software is that it can batch and automatically improve quality. For example, an application can automatically remove the shadow from your hand, level the curved sheet and make the background perfectly white and the text black. Some programs can sort documents into folders and send them directly to print or email.

However, it’s worth considering that many of these apps contain ads or require subscriptions to access premium features like text recognition or watermarking. For the average user who needs to scan a help once a month, Xiaomi or Google functionality will be more than enough.

  • 📄 Adobe Scan integrates well with the Adobe ecosystem and PDF-Formats, free of charge, creates high-quality PDF.
  • 📸 CamScanner is a classic genre with powerful filters, but has limitations in the free version and watermarks.
  • 🏢 Microsoft Lens is ideal for Office users, can scan boards and business cards, preserving the text structure.

When installing a third-party app, be sure to check the permissions requested.Scanners do need access to the camera and storage, but requiring access to contacts or location may be excessive and evidence of personal data collection.

Customization of quality and preservation formats

The quality of the final scan depends on the settings you choose before or after shooting. Most Xiaomi apps have Auto mode by default, but for important documents, it is better to switch to High or HD. This will increase the file size, but save small details, prints and signatures.

The choice of file format also plays a role. JPEG format is suitable for images where color reproduction is important (for example, color photos in a passport or diploma). However, for text documents, contracts and invoices, it is preferable to use PDF format. It provides versatility of display on any device and protects the document from accidental editing.

In the Scanner app settings on Xiaomi, you can set the default resolution. If you plan to send documents through messengers that compress images (for example, Telegram or WhatsApp), it is better to choose the average quality immediately so as not to waste traffic on transferring excessively heavy files.

⚠️ Note: Do not use the format PNG This lossless format creates very heavy files that will be inconvenient to store and transfer, unlike optimized ones. PDF.

💡

The optimal balance between quality and file size is achieved when scanning in a PDF with a resolution of 300 dpi.

Elimination and improvement of readability

A common problem with a phone scanning is the glare from the lamps or the sun, and the shadows falling from the device itself. To avoid this, try to keep the phone parallel to the document, not at an angle. If the glare is unavoidable, try changing the angle of light or moving to another place.

Another challenge is the bending of pages in books or notebooks. Modern algorithms in MIUI and third-party apps can virtually straighten pages. If the automation fails, use manual framing mode, dragging corners of the frame exactly along the boundaries of the text.

If the text on the scan looks pale, use a black and white or magic color filter that increases the contrast between the ink and the paper, making the text clearer. However, beware: on colored documents (such as those with red seals), this filter can make red elements invisible.

  • 🌑 Use a dark background under the document to make the boundaries of the sheet clearer.
  • 🔦 Turn on the flash only in complete darkness; in daylight it will create a flashlight in the center.
  • 🧹 Wipe the camera before scanning – greasy spots on the lens create the effect of “muddy” images.

Cleaning your lens regularly is a simple but often ignored piece of advice: Even microscopic contamination can significantly reduce the sharpness of small fonts, which is critical when scanning tables or small text.

Frequently Asked Questions (FAQ)
