Modern smartphones have long ceased to be just a means of communication, becoming full-fledged mobile offices, which are always at hand. For owners of Xiaomi, Redmi and Poco devices, the issue of digitizing paper media is solved without installing third-party applications, since powerful tools are already built into the shell of MIUI or HyperOS. You no longer need to look for a printer with scanning function or buy expensive equipment, because a quality camera of your gadget can replace the entire scanner.
The process of turning a text photograph into a clear one PDF-The file takes seconds and requires minimal effort on your part, and in this article we will take a detailed look at all available methods, from standard system tools to cloud services, so you can choose the most convenient option. You will learn not just to photograph paper, but to create professional-looking documents ready to be sent to government agencies or employers.
We will focus on quality settings and text recognition, because these are the parameters that often cause questions among users. Proper file preparation will avoid problems with reading text by automatic systems and make the document as readable as possible on any screen.
Use of built-in scanner in the Camera application
The fastest way to digitize paper is to use the standard Camera app, which is pre-installed on all the brand's devices. In the latest firmware versions, the company's engineers have introduced a special mode that automatically defines the boundaries of the sheet and aligns the perspective. You don't have to manually fram the image, the system will cut the extra edges of the table and align the geometry of the document.
To activate this function, open the application and find the Documents or More mode in the lower menuยป โ ยซDocuments. The camera will automatically switch to high contrast mode, removing shadows and making the text as clear as possible, which is critical for further processing of the file. Point the lens on the sheet, wait for autofocus and take a picture, after which the system will offer to save the result immediately in the format. PDF or JPG.
If the automatic boundary definition didn't work properly, you can manually preview corners, which is especially true when you're shooting documents in your passport or books, where the pages can be curved, and when you save the file, it goes to the gallery, where you can send it directly to your messenger or email.
- ๐ธ Open the Camera app and select Documents mode from the menu below.
- ๐ Hover the camera over the text and wait for the automatic selection of the boundaries with a yellow frame.
- โ Press the shutter button and edit the scanning angles if necessary.
- ๐พ Save the result by selecting the format PDF for multi-page documents or JPG photo.
โ ๏ธ Note: When shooting through a standard camera, try to avoid glare from lamps on the glossy surface of documents, as processing algorithms can count bright light as part of the text and distort information.
Using the native camera module is a balance between speed and quality that most users enjoy: you donโt have to waste time downloading heavy apps if the basic functionality is doing a great job.
Scanning through the standard Documents app
In the Android ecosystem that Xiaomi uses, there is a separate Documents system application (or Explorer in some builds) that has advanced file management functionality, which allows you not only to scan, but also immediately sort, rename and send copies you have created.
To get started, look for the Documents icon on your desktop and click on the floating scan button, usually located in the lower right corner. An interface will open where you can choose to shoot: color, black and white or photo. Black and white is ideal for text contracts and statements, as it significantly reduces the weight of the final file and increases the readability of the font.
One of the key features of this method is that you can create multi-page documents, so you can scan the first page, click Add, flip the sheet and scan the second, and you end up with one single file, and you don't have to glue the images together in third-party editors.
โ๏ธ Pre-scan check
Once the series is complete, the system will suggest using quality filters. Automatic settings are recommended, but if the text is too pale, you can manually increase the contrast. The finished file is stored in the scan folder, where it is easy to find through search.

Using Google Drive for Cloud Scanning
Many users forget that the standard Google Drive app, which is preinstalled on every Xiaomi certified smartphone, has a built-in powerful scanner.This solution is ideal for those who want to immediately save documents to the cloud, freeing up device memory. The process of integrating with a Google account ensures synchronization between the phone, tablet and computer.
To start the process, open the app, click on the plus icon in the corner and select Scan. The interface is minimal: you take a picture, the system automatically trims the excess and applies filters to remove shadows. OCR-Googleโs optical character recognition technology allows you to search text inside a scanned image, which is a huge plus for archiving.
The main advantage of this method is that the document is instantly available from any device, and once the scan is complete, the file is already on the server, and you can send a link to it to colleagues or print it out in the copy center without the help of a phone, which makes workflow as efficient as possible for remote work.
It is worth noting that this method requires an active Internet connection at the time of saving, although the photo itself can be taken offline, and download will occur when the network appears. Google Drive quality settings also allow you to choose between color and black and white mode.
Third-party applications for professional processing
If MIUI and Googleโs built-in tools donโt meet your needs, the market offers specialized applications like CamScanner, Adobe Scan, or Microsoft Lens. These programs use advanced image processing algorithms that can do wonders with bad originals: remove moire, align the color of paper, and even translate text into an editable format.
Installing this software makes sense if you're working with documents all the time and you need batch processing or table recognition. For example, Microsoft Lens is great at transferring whiteboard or business cards straight to Word or OneNote, while keeping the text structure intact. However, many features in these applications may be paid or require subscriptions.
When using third-party software, it is important to carefully monitor the permissions you give the application. Access to the camera and files is necessary, but transferring data to third-party servers for processing can raise questions for those who are concerned about privacy.
โ ๏ธ Warning: Free versions of popular scanners often add watermarks to documents or have a limit on the number of scans per day, so carefully study the terms of use before starting work.
However, for one-off tasks or for particularly complex, faded documents, the paid versions of these applications can be indispensable, allowing you to adjust the binary thresholds manually, which gives you complete control over the final picture.
Customization of quality and preservation formats
The quality of the final file depends on the settings you choose before shooting. Most applications on Xiaomi can choose the resolution of the image and the compression ratio. For official references, it is recommended to choose the maximum quality so that small fonts and prints remain readable even when zooming in.
The save format also plays a role: PDF is a universal standard for documents, as it retains layout and can contain multiple pages in a single file. JPG format is suitable for single images, but when compressed strongly, text can become blurred and compression artifacts can become noticeable.
If you scan color documents with seals, be sure to choose color mode, even if the text is black.The seals and stamps are often red or blue, and in black and white they can merge with the background or disappear, making the document invalid for some instances.
How to reduce file size without losing quality?
Remember to check the final file before sending it. Open it on the full screen and try to read the text from arm's length. If it's clear, the document is ready to use.
Tips for improving scan readability
Even the best Xiaomi camera won't do a miracle if the initial shooting conditions are poor.Lighting is a key factor.Try to scan documents in bright daylight or under uniform artificial light, avoiding shadow from your phone or hands on paper.
The background also matters. Put the document on a surface that contrasts with its color. A white sheet is ideal for a dark table or a special substrate, which will help algorithms automatically and accurately define the boundaries of the document, cutting off the background.
Stabilizing your hands or using a tripod (or just a stop for your phone) will avoid lubricating the image, especially in low light when the camera shutter speed is increased. Even microsmear can make fine text unreadable.
- โ๏ธ Use natural light at the window for better color reproduction and no noise.
- ๐ Avoid shooting against the light source so as not to get a silhouette instead of text.
- ๐งน Wipe the camera lens before every important scan, greasy spots blur details.
- ๐ Keep your phone strictly parallel to the sheet to avoid geometric distortion.
โ ๏ธ Note: Never use digital zoom when scanning documents, as it simply cuts and stretches the picture, drastically reducing the clarity of the text; it is better to come closer physically.
Compliance with these simple rules will allow you to get scans of banking quality, which are not different from those scanned on a professional MFP. Your Redmi or Poco is capable of much more than it seems at first glance.
