Device Info on Xiaomi: purpose, features and customization of visibility

Many Xiaomi, Redmi and Poco smartphone owners who are looking closely at the installed app list often come across a system component called "Device Info" or "Device Information." The question is, what kind of software is it, why is it consuming resources and can it be disabled? It's not a virus or a third-party data collector, but an important element of the MIUI or HyperOS operating system responsible for identifying the gadget on the network and for other applications.

Understanding the features of this service is critical for users who care about their digital security. The system module collects the technical characteristics of the smartphone, such as the processor model, Android version, screen resolution and unique hardware identifier, which are necessary for the correct operation of many Google services, system updates through OTA, and the functioning of banking applications that verify the integrity of the environment.

In this article, we will discuss the purpose of this component, consider the risks associated with its forced removal, and provide step-by-step instructions on how to limit its activity, you will learn how to hide your phone model from third-party sites and applications without disrupting the stability of the operating system.

The main purpose of the system component is the Device Info application (often displayed as com.android.deviceinfo or com.miui.deviceinfo) is an integral part of the Android framework, adapted by Xiaomi engineers. Its main task is to provide a standardized interface to request information about hardware and software to other applications. When you install a game, it asks this service for data about the graphics accelerator to see if the device will pull high graphics. Without this component, many programs simply would not be able to run or work as a proxy for the GPS, for the data to identify the devices, for the implementation of the sensors, for example, the sensors, for the implementation of the sensors. System identification is done in the background and is not usually visible to the user, and it is also key to Find Device and Mi Account security. If you try to log in from a new gadget, the security system will check the current settings obtained through Device Info with those stored in the cloud. ⚠️ Warning: Attempting to completely replace this component with custom counterparts may lead to disruption of Google Play Services and inability to install security updates. 💡Device Info is a system bridge between your smartphone hardware and applications, ensuring their compatibility and correct operation.

Inside the package, you can access a wide range of parameters that are classified as device telemetry, which is not only a trivial model of the phone, but also deep technical specifications. Applications with appropriate permissions may be requested through this gateway IMEI-code, serial number, MAC-Wi-Fi and Bluetooth addresses, and real-time battery power levels, varying depending on the application's request, but the basic set always includes the battery: 📱 Exact model of the device (e.g, M2102J20SG) and codename of the project. 🔢 Assembly version MIUI/HyperOS and Android security patch. 💾 The amount of operational and internal memory available to the user. 🌐 Language settings and time zone of the region. It is important to understand that the component itself does not send this data to Xiaomi or third party servers without a request. It works on the principle of "answer to a question": if the application has the legitimate right to request the device ID, the service provides the requested parameters. However, there are scenarios when this information is used for targeted advertising in system applications such as Mi Browser or Mi Music. Users, about privacy, often wonder whether it is possible to block the transfer of unique identifiers. This is partially regulated through advertising settings, but it is impossible to completely disable reading of technical specifications without root rights, since this violates the basic logic of Android applications.

The issue of uninstallation of system components is always a hot topic for enthusiasts who want to make room or increase privacy. The short answer is that simply uninstall Device Info through the standard settings menu will not work. The “Delete” button in the application management menu will be missing or inactive, as it is a secure system package. In theory, having a superuser (Root) permission allows you to delete or “freeze” this package using tools like Titanium Backup or System App Remover. However, the consequences of such actions can be fatal to the functionality of the smartphone. SIM-map, as the radio module is also linked to these identification services. A safer alternative to complete deletion is forced to stop or disable if the option is available in your firmware version. This requires you to go to the application management menu, find the process and choose the appropriate action. But even then, the system can automatically restart critical services after a while, as the dependencies of other processes will not allow it to remain asleep. The risks of removing system components.Device Info can cause Google Play to stop working, push notifications will not arrive, and banking applications will begin to issue security errors due to the inability to verify the integrity of the device.

If your goal is not to remove the service, but to hide the real model of the phone from intrusive applications or sites, the Xiaomi ecosystem has built-in mechanisms for this. This feature is especially useful if you want to test the layout of sites or avoid locking on the model of the device in games. To access the advanced display settings, do the following: Open the standard Phone app ##6484## login (CIT). Or go through the settings: Settings → The phone. → Version. MIUI (However, for direct concealment of the model in Android 10 and above (relevant to the MIUI 12-14 HyperOS and There is an Easier Way Through the Developer Menu. You need to activate the developer mode by clicking 7 times on the build number in the About Phone section. Then in the advanced settings, look for the privacy or device hiding item. Enabling this option forces the system to send generalized data to applications instead of real data, for example, instead of "Xiaomi Redmi Note 10 Pro", the application will see simply "Android Device". This helps to maintain anonymity, but it can affect the widgets that use the model to match the interface, and the granularity of the settings allows you to choose whether to hide only the model or also the serial number and the number of the user. IMEI. 📊 Do you hide the device model from the applications?Yes, it is important for privacy No, I have nothing to hide I don't know how to do it I'm afraid to break something

Control of device data access in MIUI and HyperOS is quite flexible. You can manually deny specific applications access to phone information if you think it is unnecessary. This is done through the permissions manager, where you can configure in detail what each installed application sees. For fine-tuning, go to Settings → Privacy Protection → Permissions Management → Phone Information. Here you will see a list of all the applications that requested access to Device Info. Disable the slider for those programs that you think do not need to know exactly what each installed application sees. For example, go to the model, you may clearly need to request such data. Some memory cleanup or antivirus applications require full access to system logs and device information to analyze threats. ☑️ Privacy Settings Check Open Privacy Settings Check permissions for Phone Information Revoke access to suspicious apps Turn on Advertising Tracking Protection Completed: 0 / 4

Sometimes users are faced with a situation where the application "Device Info" begins to consume an abnormally high amount of power or processor. This could be a version conflict, a cache error, or malware attempting to access data through a vulnerability, which requires diagnostic procedures, and the first step should always be to clean up the cache and the service itself. This won't delete your personal files, but it will reset display settings and temporary logs.Reset instruction: Settings → Annexes → All applications → Device Info (or Device Information) → Clean up → Clear cache If the problem persists, check for system updates. Often bugs in system components are fixed with security patches. Go to Settings → About the phone and click on the update button. If you use global firmware, make sure it's relevant, as older versions may have security holes associated with telemetry leaks. In rare cases, resetting the network settings or completely resetting to factory settings helps, but this is an extreme measure. Before doing this, make sure to back up your data. If you notice that the device is heating up when you're working with a particular application, try removing it and finding an alternative, as it can cause cyclical requests to the system service.
