The introduction of a national product labeling system has dramatically changed the way retail and logistics are approached in Russia. For business owners and warehouse employees, the Honest Mark has become a mandatory control tool. Xiaomi Redmi series smartphones, thanks to their affordable price and performance, are often the main working devices for scanning DataMatrix codes.
However, users of MIUI and HyperOS shells may encounter security features that block access to the camera or prevent the barcode scanner from working properly. Understanding these nuances avoids downtime and quickly configures equipment. In this article, we will discuss the entire process from installation to solving specific problems specific to Xiaomi devices.
The effectiveness of the labeling depends on the correct configuration of your gadget. The barcode scanner should respond instantly, and the Internet connection should be stable. Ignoring basic setting requirements can cause the application to close or not read. QR-code.
Installation and initial configuration of the application
The process of software installation on Xiaomi devices has its own features associated with the pre-installed GetApps store and the limitations of Google Play. For the correct operation of the Honest Sign, it is recommended to download the current version exclusively from the official source of the Google Play Market, since third-party versions may contain outdated encryption libraries.
Once the installation package is loaded, MIUI can display a potential hazard warning, as the application requests wide access to system functions. This is a standard protection procedure, and you need to press "Still Install" or a similar confirmation button to continue, without this step, installing the application will not be possible.
The first run requires authorization through a reinforced qualified electronic signature (UKEP) or login and password from the personal account. The interface may differ depending on the version of the operating system, but the basic functionality remains unified. It is important to immediately check that the date and time on the device are set automatically, since desynchronization will cause an error of security certificates.
☑️ Primary setting of the Honest Sign
It’s worth noting that on some Redmi Note or Redmi K models, the interface may not scale properly if the screen settings change the standard font size. Back scale to the default value so that the control buttons are clickable. It’s critical to keep a backup of the token certificate in cloud storage available from other devices in case your smartphone settings are reset.
Configure access rights and security permissions
MIUI is known for its aggressive energy saving policy, which often kills the background processes of the required applications. To maintain an honest sign, you need to manually configure permissions. Go to Settings → Applications → All applications, search the list for “Honest Sign” and select “Allowances”.
You need to activate access to the camera, microphone (for some functions), geolocation and storage. Without the right to use the camera, scanning the DataMatrix codes will not work. It is also recommended to enable permission to “Map on top of other applications” if you plan to use quick-start widgets.
⚠️ Note: If after system update MIUI The app has stopped opening, check the Security section» → «Licenses and Access. Sometimes system patches reset access rights for cryptography applications.
Special attention should be paid to battery settings. In the "Energy Saving" menu for the "Honest SIGN" application, you need to select "No Limits" mode. The standard mode can turn off the Wi-Fi module or camera when the screen is locked, which will cause the connection to the marking server to break at a critical moment.
- 📱 Access to the camera: required for scanning codes.
- 📍 Geolocation: required to fix the place of acceptance of goods.
- 💾 Files and Media: Required for saving reports and uploading documents.
- 🔔 Notifications: Important for obtaining acceptance statuses.
Working with a scanner and camera on Redmi
The quality of reading the codes DataMatrix directly depends on the camera module and the software for image processing. Xiaomi Redmi smartphones are equipped with photo enhancement algorithms that can normally "lubricate" text or change contrast, which prevents the barcode scanner from recognizing the code. In the camera settings of the application itself (if any) or in the system settings of image processing, it is worth turning off any improvement filters.
To speed up the acceptance process, you can use external Bluetooth scanners connected via a USB-OTG or connection, in which case the built-in camera of the Redmi smartphone can only be used for photo documentation, and the reader will take over the external device, this is especially true in large volumes of shipments, where the reaction speed of the built-in sensor may not be enough.
Why isn’t the camera focused on code?
If you use an integrated camera, watch for lighting. The matrixes in Redmi's budget models can make noise in low light, which reduces recognition accuracy. In such cases, it is better to turn on the flash or additional lighting. The camera resolution in the application should be set to the maximum available value for clarity.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Permission | Maximum. | Clearness of DataMatrix code |
| Autofocus. | Included | Reading speed |
| HDR | Unplugged. | Avoiding overlights on the label |
| Outbreak. | Auto/Auto/Available | Working in a dark warehouse |
Solving Connection and Certificate Problems
One of the most common problems on Xiaomi devices is the time conflict when working with electronic signatures. Security certificates have a strict validity time interval. If the time on the smartphone differs from the server one even by a few minutes, the Honest Sign will give a connection error. Make sure that the Settings menu → Additional → Date and Time switch is activated “Use Network Time”.
Problems may also arise when using corporate Wi-Fi networks with authorization through the web page (captive portal), the application may not have access to the Internet until you have logged in through the browser, in such cases it is recommended to use 4G/5G mobile Internet for initial authorization and signing of documents.
To work with electronic signature tokens (eToken, JaCarta) on Android often requires support. OTG Not all Redmi models are properly powered. USB-If the token is not identified, try using an external power source or active power source. USB-Hub.Token drivers must be compatible with the version of Android installed on your device.
Optimization of the background
MIUI aggressively manages background processes to save battery, which can interrupt the data exchange process in Honest SIGN. To prevent this, you need to lock the application in the recent apps menu. Open the recent apps list, find the Honest SIGN window, long-press on it (or pull down on some), and select the lock icon. This ensures the background process is not terminated by the cleaner system.
In addition, there is a hidden list of AutoRunners in the battery settings, so find the Honest Sign and let it autorupt, which ensures that when you restart your phone or update your system, the app can restore the necessary services to receive push notifications about the status of documents.
⚠️ Note: Do not use third-party memory accelerators or cleaners (Clean Master and analogues) with an Honest Sign. They may force the scanning process to be difficult for the system.
For maximum stability, it is recommended to disable Advanced Optimization in the developer menu. Although this step requires caution, it allows applications to stay in RAM longer. To get into the developer menu, you need to click 7 times on the build number in the About Phone section.

Use the app widget on your desktop to quickly navigate to the scanner, saving startup time and immediately activating the camera bypassing the main menu.
