How to use the scanner on Xiaomi Redmi 6

Redmi smartphones have long proven themselves as reliable devices with a wide range of functionality available to everyone. Xiaomi Redmi 6, released in 2018, is still actively used due to its practicality and optimized shell. MIUI. One of the most popular features that is often forgotten or used at a low capacity is the built-in scanner, which allows you to instantly translate paper documents into digital format, read barcodes of goods and open web pages on a daily basis. QR-marker.

Device owners often search for a separate app without knowing that the tool is already integrated into the system. The Redmi 6 camera is equipped with artificial intelligence algorithms that automatically recognize the types of objects in the frame. This means that you do not need to install third-party software from the Google Play Market, which is often overloaded with advertising and requires unnecessary permissions. The built-in tools work faster and more stable, consuming less battery life.

In this guide, we will take a look at all aspects of working with a scanner on your device, learn how to activate hidden camera functions, how to properly scan a document for printing, and what nuances are involved in working with codes in different versions of firmware.

Activation and configuration of the built-in scanner

The first step to get started is to activate the scanner correctly. In the MIUI shell installed on Redmi 6, this feature is often hidden in the depth of the camera settings or in a separate system application. The standard launch path is to find the Tools folder on your desktop and select the Scanner icon there. If the shortcut is missing, it can be added through the widget menu or found in a common list of all installed programs.

Once you start, the system will ask for permissions, and if you want to work properly, the scanner needs access to a camera to read images and access to a gallery to process the stored photos, and if you don't have those permissions, the app won't be able to function, and you may need permission to access the Internet if you want to use real-time translation or product recognition.

⚠️ Note: When setting permissions, carefully read what exactly the app is asking for.The Xiaomi system scanner is secure, but if you downloaded a third-party counterpart, it can require access to contacts or microphone unnecessarily, which is a sign of spyware.

You also need to check the settings of the camera itself. Open the Camera app, swipe across the screen in "More" mode, and select "Documents." This mode activates a special algorithm that automatically aligns the perspective and increases the contrast of the text, making it look like a scanned file, not just a photo.

For quick access to the scanner QR-You can add the "Scanner" widget directly to the desktop or set up the launch (properly pressed) on the camera icon in the locked state, if such an option is supported by your version. MIUI.

Scanning documents and photos through the camera

Redmi 6's document scanning mode allows you to create high-quality digital copies of paper. You don't have to be a professional photographer: the intelligent system will determine the boundaries of the sheet itself. You can point the camera at a document lying on a flat surface and wait for the yellow frame to automatically circle the edges of the paper. If the automation is wrong, you can manually adjust the angles of the cropping before saving.

Once the frame is taken, the system will suggest filtering. For text documents, the best option is to "Improving" or "Ch/B" mode, which removes shadows and makes the background perfectly white and the text black. This is critical for later text recognition or faxing. Color mode should only be left for documents with seals, graphs or photos, where it is important to keep the original palette.

• 📄 Auto-frame – the system itself cuts off the extra edges of the table or hands.
• 🔍 Improved sharpness – Algorithms increase the readability of fine print.
• 🌈 Color correction – removing yellow from old papers or glare from lamps.
• 📑 Packet scanning – the ability to scan several pages in a row in one PDF-file.

It is important to ensure good lighting when scanning. Avoid direct glare from the lamps on the glossy surface of the document, as the Redmi 6 camera can incorrectly process the illuminated areas, turning the text into a white spot. If the document is crumpled, try to straighten it as much as possible before shooting, although software alignment partially compensates for this disadvantage.

Work with QR-codes and barcodes of goods

One of the main functions of the scanner on Redmi 6 is to read two-dimensional scanners. QR-It's convenient not only for paying in stores, but also for fast Wi-Fi connection, adding contacts or clicking on links. The smartphone camera reads information almost instantly, even if the code is slightly damaged or pasted on a curved surface.

When you hover over a barcode in a store, the system often tries to find it in online stores like AliExpress or local markets, which allows you to quickly compare prices. However, be careful: not all codes lead to secure resources. Before clicking on a link that the scanner recognizes, always check the browser address bar.

The scan history is stored in the Scanner app, and you can go back to the codes you read if you accidentally close a page or forget to copy information, which is especially useful when dealing with a lot of labeled items or when collecting data for inventory.

Using Google Lens and Text Recognition

In the newer versions of MIUI firmware available for Redmi 6, the camera features are closely integrated with Google Lens technology, which takes scanning to a new level, allowing you not only to capture the image, but also to understand its contents, you can point the camera at the store sign in a foreign language and see the translation of text directly over the image in real time.

Text Recognition (OCR) allows you to extract printed text from photos. It's an indispensable tool for students and office workers. Once you take a picture of a page in a book or handwritten notebook, you can copy all the text into a clipboard and paste it into notes or messengers. Recognition accuracy depends on handwriting and print quality, but for print typefaces it's almost 100 percent.

Google Lens can also recognize dog breeds, plant breeds and landmarks, and point a camera at a flower in the park, and the system will tell you its name and description, and these features require stable Internet access, because the image processing takes place on the company's servers.

⚠️ Attention: Translation and text recognition is consuming mobile data traffic. If you are roaming or have a limited rate, it is recommended to connect to Wi-Fi before actively using Google Lens.

Comparison of built-in scanner and third-party applications

Users often wonder why you need a built-in scanner when the Play Market has hundreds of alternatives? The answer lies in optimization and security. The built-in Mi Scanner app has minimal weight, does not show intrusive advertising and does not collect unnecessary user data. Third-party applications often require access to a microphone, geolocation and phone book, which is redundant for simple scanning.

Below is a table comparing the capabilities of the standard solution from Xiaomi and popular third-party counterparts such as CamScanner or Adobe Scan.

However, if you need specific features like Excel packet recognition with formatting saved or professional color correction, third-party apps can be more powerful. For 95% of household tasks, Redmi 6 is enough without installing additional software.

Elimination and technical nuances

Despite the reliability of the system, Redmi users 6 It can be difficult, and often the camera will not focus on the code if the distance to the object is not right. QR-code 10-20 If you step further, the small code may not count, and if you get too close, the camera will not be able to focus because of the minimum focusing distance of the lens.

Another common problem is lens contamination. The Redmi 6 camera doesn't have laser autofocus, it relies on contrast or phase autofocus (depending on the processor modification). Fat fingerprints on the camera glass drastically reduce the quality of the scan, making the image blurry. Rub the lens with soft cloth before every important scan.

If the scanner stopped opening or crashes immediately after launch, try clearing the app's cache. Go to Settings → Apps → All Apps → Scanner → Memory → Clean. In extreme cases, removing app updates or completely resetting the camera settings will help.
