Xiaomi and Redmi smartphones have long since ceased to be just callers, becoming powerful document tools. The built-in MIUI shell (or the new HyperOS) offers a native scanning solution that users often ignore in favor of third-party apps. However, the system scanner has unique advantages, such as deep integration with the gallery and the absence of intrusive advertising.
Understanding how to use the scanner in the Xiaomi Redmi smartphone will allow you to quickly digitize checks, contracts and texts without installing unnecessary software. This saves time and space in the memory of the device.
Where to find and how to run a system scanner
The first thing that a device owner needs to know is that the individual Scanner app on the desktop may not be the default, and most often, this feature is built right into the standard Camera app. To activate scan mode, open the camera and swipe across the screen or select the appropriate mode in the menu on the left.
An alternative and more functional way is to use a system utility. Find the Tools folder on your desktop and launch the Scanner app. This is where advanced settings like recognition are available. QR-codes, translation of text and scanning of documents in PDF.
- 📱 Open the Camera app and select Documents mode in the lower menu.
- 🔍 Find the Scanner icon in the system utilities folder on the home screen.
- 👆 Use the Quick Commands widget on the locked screen for instant start-up.
If you're a hard-copy type person, it makes sense to put the scanner icon on your desktop, so you can grab your finger on the app icon in the menu of all the programs and drag it to a convenient location, which will speed up access to the feature in critical situations.
Setting up the quality and scan formats
The quality of the final file depends on the correct settings before the process begins. In the scanner interface, you need to pay attention to the parameters of the resolution and save format. By default, the system can choose an automatic mode, which does not always correctly determine the type of document.
For text documents, the best choice is Black and Expanded Contrast, which reduces file size and makes text more readable by removing background paper noise. For photos or color schemes, be sure to switch to Color Mode.
💡
Use Magnify to scan small text on labels or instructions – it works like a digital magnifier with a snapshot.
It is also important to adjust the output format. Xiaomi system scanner allows you to save results as JPG images or multi-page PDF documents. For archiving contracts, you should choose PDF, since this format is more difficult to edit and easier to print.
| Parameter | Document mode | Photo mode. | Regime «ID Map» |
|---|---|---|---|
| Colour processing | Auto-correction, removal of shadows | Natural colors, HDR | Cross-linking of two sides |
| File format | PDF or JPG | JPG | JPG (linked) |
| Recognition | Text (OCR) | Facilities | Personal data |
⚠️ Warning: When scanning important legal documents, always check the edges of the frame. Automatic cropping can accidentally cut off part of the signature or seal if the frame detection worked inaccurately.
Step-by-step instructions: scanning documents
The process of creating a digital copy of a document involves several steps, each of which affects the outcome. First, prepare the surface: it must be flat and contrasting to the paper. Place the document on a dark table if it is white so that the camera can clearly define the boundaries.
Run the scanner and point the camera at the document. The system will automatically try to find the rectangle. If the frame appears but it's curved, take your time to take a picture. Line the smartphone parallel to the plane of the table. Press the shutter button or wait for the auto-start.
☑️ Checklist of the perfect scan
After the image opens the editor, you can manually adjust the trimming angles if the automation is wrong, then apply quality filters, and the final step is to save the file to the selected folder or send it directly to the messenger.
To create a multi-page document, don’t save each sheet separately. Use the Add Page feature (the + icon in the scanner interface) to scan the next sheet and add it to the same PDF file.
Utilizing OCR: Text Recognition from Images
One of the most powerful features of the built-in scanner is the Optical Character Recognition (OCR) technology, which allows you to turn a picture of text into an editable file, which is indispensable for students and office workers who need to transfer text from a paper book or signage to notes.
To take advantage of this feature, scan a document and click the "Unclose Text" (or "Text") button in the bottom editor menu, the system will analyze the image and highlight the text blocks, you can copy the entire text as a whole or select a specific paragraph.
Supported OCR languages
Recognition accuracy depends on the quality of the original image. If the text is blurred or handwritten indistinctly, the system may make errors, and in such cases, it is recommended to use the "Increase" mode before scanning, so that the camera focuses on the details.
Scanning. QR-codes and real-time translation
In addition to documents, the scanner in Redmi is excellent at handling the scanner. QR-You don't have to look for a special app in the Play Market. Just open the Scanner, point the camera at the code, and the smartphone instantly reads the information.
If the code leads to a site, the system will prompt you to open a link, and if it's Wi-Fi, the phone will suggest that you automatically connect to the network, which is faster and safer than using third-party software, which often requires unnecessary permissions.
Another useful feature is real-time translation, where you can hover your camera over a foreign language text, and the scanner will replace the original text with a translation directly on the screen, and it supports translation from English, Chinese, Japanese and other languages.
- 🌐 Translation of menus in restaurants and signs on the go.
- 🛒 Reading barcodes of goods to search for prices on the Internet.
- 🔗 Quickly click on links without manually entering the address.
Typical problems and methods of their solution
Despite the stability of the work, users may face certain difficulties, most often problems are associated with permission settings or contamination of the optics. If the scanner does not see the border of the document, wipe the camera with a soft cloth.
Another common issue is the application's failure to open or "deleting" when trying to save a file, which can be due to a crowded cache.
⚠️ Note: If after updating the firmware scanner stopped working correctly, try resetting the settings of the application "Camera" and "Scanner" in the "Applications" section» → «All applications» → «Clear the data».
It’s also worth checking for updates to the system components of MIUI. Sometimes bugs in the scanner work are fixed with security patches or updates to Google Play services.
💡
Regularly cleaning the cache of the Scanner and Camera app prevents 90% of errors when working with documents and text recognition.
