Modern smartphones of the brand Xiaomi under shell control MIUI or new HyperOS offer a variety of ways to simplify interaction with the outside world, and one of the most useful tools is fast connection to wireless networks. Instead of manually entering complex passwords consisting of dozens of characters, uppercase and lowercase, and special characters, users can use technology QR codesThis method not only saves time but also minimizes the likelihood of data entry errors, which is especially important when using guest networks or complex corporate access keys.
Scanning process on devices Redmi may seem non-obvious to those accustomed to the standard behavior of other versions Android, as manufacturers often change the layout of functions in system apps. Device owners need to know exactly where to look for the built-in scanner and whether they need to install additional apps or simply open the default camera. Understanding these nuances allows for instant internet access in cafes, offices, or when visiting friends, simply by pointing the camera at a special square barcode.
In this article, we will examine in detail all the available methods for reading codes on smartphones. RedmiWe'll look at potential camera access issues and offer alternative solutions if standard methods don't work. You'll learn how to properly configure permissions, where to find scan history, and what hidden system features might be useful in everyday use. wireless networks.
Using the default Camera app
The most obvious and fastest way, which should work on most modern models Redmi with the current firmware version, is to use the standard Camera app. Engineers Xiaomi integrated the recognition module QR codes directly into the viewfinder, which eliminates the need to open additional programs. However, it's worth keeping in mind that in some regions or on older versions MIUI This feature may be disabled by default or require activation in the settings.
To get started, launch the Camera app and point the lens at the code, ensuring it's in focus and well-lit. The system will automatically recognize the pattern and prompt a pop-up notification with an action, such as "Connect to Wi-Fi." If nothing happens, the scanning function may be disabled and must be enabled manually in the camera app's settings menu by finding the corresponding "QR Code Scanner" toggle.
⚠️ Note: If the camera focuses but the connection prompt does not appear, check that the lens is not covered by a protective glass or case, and also wipe the lens, as greasy stains can interfere with the reading of fine details of the code.
It's important to remember the distance: you shouldn't hold the phone too close, so the camera has time to focus, but you shouldn't hold it too far, so the code takes up a significant portion of the screen. The optimal distance is usually between 15 and 30 centimeters. After a successful read, the system Android will ask for confirmation to connect to the network, and after clicking the "Connect" button, the smartphone will automatically enter the password and establish a connection.
Scanner via Control Center and Notification Panel
If you find the camera inconvenient to use or the function does not work, the shell MIUI Provides alternative access to the scanner through the system interface. A separate widget or shortcut for quickly launching the scanner is often located at the top of the screen, in the notification shade, or in the expanded control center. This is especially convenient when the camera is busy with another process or if you want to quickly check a code without launching a heavy camera app.
To find this tool, swipe down from the top of the screen to open the control panel and carefully examine the available icons. If the "Scanner" or "QR" icon isn't on the first screen, tap the edit button (usually an icon with three dots or a pencil) and add the desired widget from the list of available ones. Once added, the shortcut will always be at hand, allowing you to launch a scan with a single tap.
- 📱 Open the notification panel by swiping down from the top.
- 🔍 Find the "Scanner" icon (may be called "Code Scanner").
- ⚙️ If there is no icon, go to the panel editing mode and add it.
- 📸 Point the camera at the code for instant reading.
Using the system scanner through the control panel is often more reliable, as this module is less susceptible to changes in camera app updates. Furthermore, it immediately suggests actions based on the code's content: if it's a link, it will open the browser; if it's text, it will display it in a window; and if it's data Wi-Fi — will offer a connection. This is a universal tool that every owner should have configured. Redmi.
The Scanner app in the Tools folder
In the ecosystem Xiaomi There's a separate system app called "Scanner." It's usually located in the "Tools" folder on your desktop and is a more advanced version of the camera's built-in feature. This app is designed specifically to work with various types of codes and offers advanced functionality, including scan history and the ability to manually enter data or upload an image from your gallery.
Once you launch the Scanner app, you'll see an interface optimized specifically for barcode scanning, with additional control buttons. Here you can switch between scanning modes, turn on the flash for working in low-light conditions, and, most importantly, upload an image of the code from your phone's memory. This is indispensable if you've received a screenshot of the access code via messenger and can't print it or display it on another screen.
⚠️ Note: The Scanner app may request permission to access files and media. Without this permission, the image upload feature from the gallery will not work, so be sure to agree to the system requests when you first launch the app.
The main advantage of using a separate app is the history. All previously scanned codes are saved in a list, allowing you to return to them later if you accidentally close the window with a password or link. In the context of connecting to Wi-Fi This is useful if the network requires re-login or if you want to transfer data to another device by generating your code based on the stored data.
Why do you need scan history?
History in the Scanner app is saved locally on your device. This is convenient if you scanned a friend's Wi-Fi code but forgot to connect immediately. You can find the entry in your history a week later and connect again without asking for the password.
Comparison of scanning methods on Redmi
The choice of the appropriate scanning method depends on the specific situation and the version installed on your Redmi operating system. To help you navigate the options, we've prepared a comparison table showing the pros and cons of each method. This will help you understand which tool is best for you, whether you're quickly connecting to a guest account or working with a code archive.
| Method | Access speed | Having a history | Working with pictures |
|---|---|---|---|
| Camera app | High | No | No |
| Control Panel | Average | Partially | No |
| Scanner app | Average | Yes | Yes |
| Google Lens | Low | Yes (in the cloud) | Yes |
As the table shows, the Camera app is faster, requiring minimal interaction, but lacks functionality. If you just need to quickly connect right away, it's the perfect choice. However, for more complex tasks, such as code analysis or data saving, a dedicated Scanner app or even third-party solutions are better if the built-in ones aren't up to the task.
It is also worth noting that on different versions MIUI (Global, China, EEA) The interface and item names may differ slightly. If you don't see the described features, try updating your system apps through the store. GetApps or Google Play, as developers often improve recognition algorithms and change the layout of controls.
Alternative methods and Google Lens
In cases where standard means Redmi If for some reason the code doesn't work (for example, the code is corrupted, has a non-standard format, or is of poor print quality), alternative methods come to the rescue. One of the most powerful tools is Google Lens (Google Lens), which is often built into the Google app or accessible through a desktop search widget. Google's algorithms often handle complex cases better than manufacturers' standard scanners.
To use this method, simply open the Google search widget, tap the camera icon, and point your phone at the code. The system will not only recognize the data but also offer additional actions, such as translating text if present near the code or searching for similar images. This is especially useful if the code is on a complex background or has low contrast, which confuses standard scanners.
- 🌐 Open the Google app or search widget.
- 📷 Click on the camera icon (Google Lens).
- 🎯 Hover over the code and wait for recognition.
- 🔗 Click on the link or connect button that appears.
Another option is to use third-party apps from the store. Play MarketIf built-in features are completely missing (which is rare, but can happen on very old or custom firmware). However, when installing such apps, be careful and choose only proven, highly rated solutions to prevent hackers from accessing your camera and location data.
Security Solution and Settings
Despite the simplicity of the technology, users sometimes encounter problems when scanning codes on RedmiThis is most often due to a lack of necessary permissions for the camera or scanner app. If the app launches but doesn't respond to the code, go to Settings → Apps → All apps, find "Camera" or "Scanner", select "Permissions" and make sure that camera access is allowed.
Problems may also arise due to energy saving settings. System MIUI is known for its aggressive memory management and may kill background scanning processes or limit their functionality to save battery life. It's recommended to check the battery settings for the scanner app and set it to "No Limits" to ensure stable operation.
⚠️ Note: The interface and settings layout may change with MIUI and HyperOS updates. If you can't find the item described, search your phone's settings by entering the keywords "Permissions" or "Battery."
Remember to be safe: never scan codes from untrusted sources, especially if they come as messages from unknown numbers or are posted on questionable stickers in public places. Attackers can use QR codes to redirect to phishing sites or automatically connect to fake Wi-Fi hotspots that will intercept your traffic.
☑️ Checking scanner settings
Why does my phone see the code but not connect to Wi-Fi?
This most often occurs if the code contains an error in the password or if the network uses a security protocol that your phone doesn't support (for example, very old encryption standards). Another possible issue is that Wi-Fi is disabled on your phone or airplane mode is enabled. Check that Wi-Fi is active and try forgetting the network in settings before reconnecting.
Is it possible to scan a code from another phone's screen?
Yes, this is a completely normal practice. Modern smartphone cameras Redmi They can easily read codes displayed on LCD or OLED screens of other devices. The key is to reduce the source screen's brightness to eliminate glare and ensure good contrast.
Where is the scan history stored on Redmi?
History is saved only in the Scanner app (a separate app in the Tools folder). The standard camera typically doesn't record history for privacy reasons, so it's best to save important codes to notes or take a screenshot immediately.
What to do if the Wi-Fi QR code is unreadable?
Try changing the lighting, cleaning the camera, or moving your phone closer or further away. If the code is on the screen of another device, change the angle to eliminate the moiré (wavy lines). As a last resort, ask the network owner to show you the password in plain text or use the "Share Wi-Fi" feature via a QR code on the source device if it's an Android.
