Scanning documents through a Xiaomi smartphone has long been an alternative to bulky MFPs โ modern models (from the budget Redmi Note to the flagship Xiaomi 14) cope with the task as well as specialized equipment. But few people know that the quality of the scan depends not only on the camera resolution, but also on the right software, lighting and even the angle of shooting. In this article, we will analyze all the available methods โ from built-in MIUI tools to hidden functions of the Google Drive application, and also reveal professional secrets that will turn your Xiaomi into a portable premium scanner.
We'll focus on the common mistakes: why scans are curved, how to avoid glare on glossy paper, and what to do if a document doesn't fit in the frame. And for older models (like the Redmi 5 or Mi A2), we'll give you workarounds when standard features are not available. At the end, we'll give you a comparative table of methods for speed, quality and convenience so you can choose the best option for your tasks.
1. built-in Scanner app in MIUI: where to find and how to use
Since MIUI 12, Xiaomi has introduced its native Scanner app, which many users donโt notice โ itโs hidden in the Tools folder or searchable โ and uses Xiaomiโs algorithms to automatically trim edges, correct perspective, and improve readability, with the main benefit of being offline and no advertising.
To take advantage of it:
- ๐ Open a search by phone (swipe down on the home screen) and type โScannerยป.
The result is saved in PDF or JPEG format (selected) in the Scanner folder in internal memory, a unique feature: in the application settings, you can turn on the Smart Scan mode, which automatically recognizes the type of document (passport, receipt, business card) and selects the optimal shooting parameters.
โ ๏ธ Attention: On models with MIUI No native scanner is 11 or below, in which case use alternative methods from the following sections.
2.Google Drive: a hidden scanner with cloud storage
Few people know, but Google Drive has a built-in document scanner that is as good as specialized applications, and the advantages of this method are: automatic upload to the cloud, support for OCR (text recognition) and the ability to share scans. Minus โ you need an Internet connection to synchronize.
Instructions:
- Open the Google Drive app on your Xiaomi.
To improve the outcome:
- ๐ฆ Turn on the flash if the document is dark or lighting is weak.
- ๐ Use hand-trimming if the automatic trimming has worked inaccurately.
- ๐ Activate the option โRecognize textโ to search for words inside PDF.
Make sure the document is on a flat surface.|
Turn off HDR mode in camera settings|
Make sure there is enough space in the cloud.|
Use natural light (avoid yellow light bulbs)-->
โ ๏ธ Note: If the scan is blurry, clean the camera lens of dust โ on Xiaomi with a retractable camera (for example, Mi Mix 3) this is especially true.
3. Applications from third developers: top-3 Xiaomi
If the built-in tools donโt work, consider third-party apps. We tested dozens of options and selected the top three for Xiaomi devices, given the balance of quality, speed and lack of advertising.
| Annex | Advantages | Deficiencies | Ratings. |
|---|---|---|---|
| CamScanner | OCR in 60+ languages, cloud storage, manual perspective correction | Paid subscription for HD-export | 4.8/5 |
| Adobe Scan | Integration with Adobe Acrobat, Automatic Text Improvement | Registration is required | 4.7/5 |
| Microsoft Lens | Free, export to Word/Excel, support for tables | Less customization than competitors | 4.6/5 |
To install, go to Google Play and type in the name of the app. After installing:
- Open the app and allow access to the camera and storage.
- Select the Document mode (in some applications, Scan).
- Take a picture of the sheets. Most programs automatically combine them into a single PDF.
- Edit the result: cropping, rotation, filters (for example, "Black and white" for better readability).

CamScanner has a hidden Smart Lighting feature, which you can turn on in your settings to automatically adjust the shadows on a document in low light.
4.Scan through Notes (Notes): Lifehack for fast scans
The MIUI Notes app can not only save text, but also scan documents, and it is suitable for quick scans of checks, receipts or small sheets, which are inferior to specialized tools, but faster.
How it works:
- Open your notes and create a new note.
- Click on the + icon โ select Scan.
- Point the camera at the document. The app will automatically take a picture when it detects edges.
- Save the result โ it will be attached to the note in the form of an image.
Features of the method:
- ๐ The scan is attached to a note that is convenient for the organization (for example, you can create a folder "Documents 2026ยป).
- ๐ No exports to PDF โ only JPEG or PNG.
- ๐จ You can draw over the scan (for example, emphasize important lines).
โ ๏ธ Attention: There's no perspective correction in the notes. If the document is crooked, the scan will be distorted.
5. Professional chips: how to make a scan perfect
Even with the best software, the results can be disappointing, if you don't take into account the technicalities. Here are 7 rules that professionals use to scan documents on smartphones:
- Lighting: Use two light sources from different sides (like table lamps) to avoid shadows. Natural light from the window is the best option, but avoid direct sunlight.
- Shooting angle: Keep the camera strictly perpendicular to the document. On Xiaomi with a wide-angle camera (for example, Redmi Note 12 Pro+), you can use zoom ร 1.5 to reduce distortion at the edges.
How to scan multi-page documents without errors?
Xiaomi models with a telephoto lens (such as the Xiaomi 13 Ultra) can use an optical zoom ร 2 or ร 3, which will reduce distortion compared to shooting with the main camera. But don't overdo it: digital zoom spoils quality.
6. Problem solving: blurry, glare, curved scans
Even if you follow all the rules, you can have defects, and let's look at the typical problems and how to fix them.
| Problem. | Reason. | Decision |
|---|---|---|
| Blurred text | Trembling hands, weak lighting, dirty lens | Use a timer or a tripod. Clean the camera with microfiber. |
| The glare on the glossy paper | Direct light from lamp or sun | Remove at an angle of 30-45 ยฐ or cover the document with matte glass. |
| Curved edges | Non-perpendicular shooting, curved document | Enable the option โPerspective Correctionโ in the scanner settings. |
| Scan's too dark. | Weak flash, dark document | Increase exposure in manual camera mode or use an external light source. |
If a document doesnโt fit into a frame (e.g., an A3 diploma), take a photo of it in parts, and then combine it in an editor (Adobe Scan has a feature called Stitch Scans). For Xiaomi with an ultra-wide-angle camera (e.g., Poco X5 Pro), you can use Panorama mode, but the quality will be lower than with step-by-step shooting.

Use the mode to scan passports or IDs ยซID-Map in CamScanner โ it automatically crops the document to the standard ISO It improves the contrast of the text.
7. Alternative methods: scanning without a phone
If your Xiaomi is temporarily unavailable (for example, it is dead), and the document needs to be scanned urgently, use alternative methods:
- ๐ป Scanning through a computer: Connect Xiaomi to a PC USB, open the folder DCIM and drag a photo of the document to Adobe Acrobat or iLovePDF online service for conversion to PDF.
- ๐จ๏ธ MFP or printer: If there is a multifunction device nearby, send the document to print in format PDF (Most modern printers support scanning. USB-accumulator).
- ๐ Online services: Upload a photo of the document to sites like Online2PDF โ They convert the image into a scan with perspective correction.
For Xiaomi Mi Share-enabled owners (like the Redmi Note 11): You can scan a document on another phone (a friend or colleague) and instantly forward it to yourself through this feature without losing quality.
