How to scan a document via Xiaomi phone: a full guide

The modern smartphone has long since ceased to be just a means of communication, turning into a powerful mobile office that is always in your pocket. Owners of Xiaomi, Redmi and POCO devices are especially lucky, as the MIUI shell and the more recent HyperOS offer deep capabilities for working with text and images. You no longer need to search for a bulky MFP or run to the copier to save a paper version of the contract, help or extract in digital format.

The process of digitizing paper on these devices is simplified by integrating artificial intelligence into the camera and system applications. Xiaomi’s built-in perspective-alignment algorithm can automatically remove distortions even when shooting at an angle, which is critical for official documents, and it allows you to obtain files that look like they were printed on a laser printer, rather than photographed hastily.

In this article, we will take a look at all the scanning tools available, from native tools to advanced third-party solutions. We will look at the nuances of text management, readability improvements, and fast file transfer. Get ready to turn your gadget into a universal scanner that works faster than any office equipment.

Use of the built-in Scanner application

The fastest and most obvious way to get a digital copy of a document is to use a pre-installed system application. On Xiaomi smartphones, it is usually called simply “Scanner” and has a characteristic icon with a camera and a square image, which works even without an Internet connection, since the basic image processing functions are built into the firmware.

To start, you need to start the utility and select Documents mode from the bottom menu. The camera automatically recognizes the boundaries of the sheet of paper, highlighting them with a blue or yellow frame. You just have to press the shutter button, after which the system will prompt you to correct the cropping and apply filters to improve the readability of the text.

• 📄 Documents mode automatically aligns perspective and removes shadows.
• 🌈 Filters “C/B” and “Increase contrast” make the text as clear as possible.
• 💾 Ability to save immediately in format PDF or JPG.
• 📤 Quick sending via Mi Drop, Bluetooth or instant messengers.

Importantly, the quality of the final file is directly dependent on the lighting and the purity of the lens. Clean the camera before you start to avoid blurring small fonts. The application allows you to scan several pages in a row, forming a single multi-page document, which is extremely convenient for contracts or passports.

⚠️ Warning: When scanning glossy documents (such as laminated IDs), avoid using a flash as it will create a glare that will overshadow the text.

Scanning through Google Lens and Google Drive

If a standard app doesn’t fit or isn’t available in your firmware version (often found in global versions), Google’s ecosystem services come to the rescue. Google’s app or Google Lens widget are integrated into most Android smartphones and offer impressive text recognition accuracy.

You can run the scan through the Google search widget on your desktop by clicking on the camera icon, or through the Google Photo app by opening the desired image and selecting the appropriate function. Google algorithms are famous for their excellent OCR (optical character recognition), which allows you not only to save a picture, but also copy text from it.

Another powerful tool is Google Drive, which has a separate scan feature that automatically uploads the result to your cloud storage, ensuring that even if your phone is lost or broken, your important documents remain safe on the server.

• 🔍 Instant recognition and copying of text from the image.
• ☁️ Automatic synchronization with Google Drive cloud storage.
• 🗣 Support for real-time text translation through the camera.
• 📝 Possibility to search the contents of scanned documents.

Google is especially relevant for text data users, so you can scan a page of a book and translate it immediately into another language or copy the contact details from a business card, and it will identify the fields and trim the extra ones, leaving only useful information.

Use Text Mode in Google Lens to copy handwritten notes from a board or notebook directly into your smartphone clipboard without having to reprint them manually.

Third-party applications for professional work

For users who require advanced features, such as batch processing of hundreds of pages, recognition QR-For example, when you use code in mass mode or integration with corporate clouds (Dropbox, OneNote), you should pay attention to specialized software. Application stores offer many solutions that are tailored to specific tasks.

CamScanner, which provides advanced image-cleaning algorithms, has long been a market leader, and it can remove the noise from paper, make the background perfectly white and the text black, mimicking the work of a professional scanner, but many of the features in these applications are available on a paid subscription.

The alternative is Adobe Scan or Microsoft Lens, which integrates well with office suites and allows you to immediately edit the scanned text or convert it to Word format, which saves time if you need to not just save a document, but change it.

The third-party application is worth choosing if you work with documents daily. Free system tools are good for one-time tasks, but specialized software gives control over the color, resolution and format of the output of the file. Be sure to check the permissions that the application requests so that you do not transfer unnecessary data.

Customization of quality and preservation formats

The quality of the final document depends not only on your Xiaomi camera matrix, but also on the right settings. Most applications default to an automatic mode that seeks to balance colors. However, documents often require a forced switch to high contrast mode or a black and white filter.

Scan resolution is another important parameter. For normal text help, 150-200 DPI is enough to ensure a small file size. If you scan small-print documents, drawings or photos, set the maximum resolution available so that text remains readable as you zoom in.

The save format also plays a role. The universal standard for documents is PDF, as it saves layout and opens easily on any device. JPG format is suitable for images or documents that are planned to be sent through heavy compression messengers. PNG format is better used for documents with graphs, since it does not lose quality when compressed.

• 📉 Reduce resolution for text files to save memory.
• 🎨 Use color mode only for documents with seals and signatures.
• 📑 Group the pages into one PDF-file-to-transfer.
• 🔒 Protect the important ones. PDF-Password files when saved.

Remember to check the size of the final file. Too heavy scans may not go through the limitations of email services or messengers. In the Scanner app settings on Xiaomi, you can often choose the compression quality of JPEG, which helps to find a balance between readability and volume.

⚠️ Note: When scanning passports and watermarked documents, do not use aggressive Magic or Black and White filters as they can completely remove the security elements and the copy will be considered invalid.

Text processing and translation of documents

Today’s Xiaomi smartphones have enough processing power to process text directly on the device. After scanning, many apps offer a “Disclose Text” (OCR) feature, which turns the picture into an editable text file that can be opened in a notebook or Word.

This feature is especially useful for students and office workers who need to transfer information from a paper source to a digital form. You don't have to reprint hundreds of pages manually - the camera will do it in a few seconds. MIUI/HyperOS high-pitched.

If you come across a document in a foreign language, Google's built-in tools or specialized apps will offer instant translation, you point the camera at the text, and it will be displayed on the screen in your language, saving the original formatting, which is indispensable when reading instructions for technology or menus in a restaurant.

Organization and transfer of scanned files

Once a document is scanned, it needs to be saved correctly and possibly transferred. Chaotic file storage in the Downloads folder will quickly lead to confusion. It is recommended that you rename the files immediately after scanning, indicating the date and essence of the document, for example: 2023_10_25_Dogovor_Arenda.pdf.

Xiaomi’s Mi Drop (or ShareMe) technology is ideal for transferring large amounts of data from a smartphone, allowing files to be transferred to other Xiaomi or Android devices over Wi-Fi Direct at high speeds without consuming Internet traffic, much faster than sending documents via Bluetooth or instant messengers.

Also worth considering is the possibility of automatically uploading scans to the cloud, so by setting up the scanner folder to sync with Google Drive or Yandex.Disk, you back up when you create a file, which protects against accidental deletion and frees up space in the phone's internal memory.

Keep your personal data safe. Don't keep scans of passports, TINs and bank cards in the public gallery, put them in a Second Space or archive them with a password before you send them. Digital hygiene is as important as the physical preservation of your papers.

💡

Automatic scanning by folder and cloud synchronization are key to document order and the security of your personal data.
