Users of Xiaomi, Redmi and POCO smartphones often face incomprehensible system queries that cause confusion and even concern for data security. One such request is “environmental sharing.” This phrase, which appears in notifications or permission logs, sounds mysterious, but actually hides a very specific technical process.
In Android, and especially in the MIUI and HyperOS shell, the term “environmental sharing” usually refers to scanning Bluetooth devices and Wi-Fi networks in your immediate vicinity. It’s not just a whim of developers, but a functional necessity for geolocation services to work, finding devices in the smart home, and quickly transferring files. However, when the system constantly requests permission to do this, the question arises: why is this happening and is this not surveillance?
In this article, we will look at what’s behind the phrase “environmental sharing,” why Xiaomi so insistently requests these rights, and how to manage these settings, and learn which apps use this protocol most often, and whether it’s worth limiting their access to your smartphone’s network interfaces.
What does the “environmental exchange” request mean in Android
Technically, the phrase “scanning for devices” (or “Exchange with surroundings”) is a translation of the system processes for finding Bluetooth devices and Wi-Fi networks. When an app requests access to this feature, it wants to get a list of gadgets that are near your phone.
It is important to understand that many Android 10, 11, 12 and later features require a geolocation module enabled (GPS), Even if the application doesn't use the maps directly, the security system is built so that the ether scan can theoretically be used to determine the user's location by the map. MAC-This is why the request for "interview with the environment" often comes in conjunction with access to the location.
⚠️ Note: If you see persistent requests to share data with your environment from an unfamiliar application, this may be a sign that the program is trying to collect data about your location or nearby devices without an explicit need to do so.
Users often confuse this process with file transfer, but in the context of system resolutions, it is precisely radio modules. The smartphone “listens” to the air to see who you can contact, without this you can not work the “Fast Connection” function, broadcast the screen to a Xiaomi TV or search for lost headphones.
Why apps need to access Bluetooth and Wi-Fi
Many people wonder why a simple flashlight or calculator can request access to network scanning. In fact, modern applications often contain ad modules or analytics that use Bluetooth Low Energy (BLE) to target ads or analyze shopping mall traffic.
First of all, they're the services of the manufacturer itself. Apps like Mi Home, Xiaomi Wear, or Mi Fit (Zepp Life) can't function without constantly scanning their environments. They need to find gateways, cameras, robot vacuum cleaners, and bracelets. If you stop sharing with your environment, the smart home will stop responding to commands, and the bracelet will not be able to synchronize heart rate data in real time.
And then there are Google services that are responsible for precise location, which scans the Wi-Fi networks around to get coordinates if the GPS signal is weak (e.g., indoors), which increases the speed of navigation in Yandex.Navigator or Google Maps, and disabling this feature can make the search for satellites longer.
Also worth mentioning are fast data features like Mi Share or Quick Share. To detect a recipient within a few meters, the phone needs to constantly exchange data packets with the environment, without which you simply won’t see the list of available devices for transferring photos or videos.
How to Manage Permits for Xiaomi and Redmi
Control over which apps can scan your environment is in the privacy settings. In the MIUI and HyperOS shells, this process is as detailed as possible. To check who has access, you need to go to the Settings section, then select Privacy Protection and then Special Permissions (or Permissions → Additional Permissions).
Here you will find items related to Bluetooth, Wi-Fi and exact location. It is recommended to conduct an audit of the list of applications. If a simple text editor or a solitaire game requires the right to “sharing with the environment”, this is an occasion to think about the feasibility of installing them or the need for such rights. You can manually disable the switchboard for suspicious programs.
☑️ Permit verification
System services are particularly important, such as MIUI Daemon or Analytics, which can collect environment data to improve system performance, and if you care about privacy, access to these services can be restricted, but this can affect the personalized recommendations and some features of the smart lock screen.
Impact on battery and performance
Constantly scanning Bluetooth and Wi-Fi networks is energy-intensive. The smartphone’s radio module is active, which leads to increased battery consumption. If you notice your Xiaomi or Redmi is running out quickly, it may be the fault of an app that uncontrollably requests “environmental sharing” in the background.
To diagnose a problem, go to Settings → Battery → Charge Consumption. See which apps consume the most power. If you see a navigator or messenger there that you didn't use at this point, but it's hanging in the background, check its permissions. It might be worth banning background activity or limiting access to geolocation to "Only in Use" mode.
| Type of application | Do you need an exchange with your environment? | Impact on the battery |
|---|---|---|
| Navigator (Yandex, Google) | Yes (for accuracy) | High. |
| Smart Home (Mi Home) | Yeah (device search) | Average. |
| Fitness tracker | Yeah (synchronization) | Low/Mediocre |
| Games / Photo editors | No (usually) | Low (no access) |
💡
Use Power Saving mode to automatically limit background network scans for applications you are not currently using.
Optimizing background processes is key to a long smartphone life: In the battery settings, you can select “No Limits” mode only for applications that are critically important for constant communication (for example, messengers), and for others, leave the standard limitations of the MIUI system.
Problems with connecting smart devices
Owners of the Xiaomi Smart Home ecosystem often face a situation where new devices are not added. The camera, light bulb or socket are on the indicator of readiness, but the phone does not see them. 90% of the time the problem lies in the lack of permission to share with the environment for the Mi Home application.
When you first set up any gadget, the app scans the airwaves for devices in pairing mode. If access to Bluetooth or a local Wi-Fi network is denied by a user or security system (for example, an antivirus), the addition process is interrupted, so when you first start Mi Home, you need to confirm all access requests.
⚠️ Note: When setting up new smart home devices, make sure you not only have Bluetooth enabled, but also geolocation access, as this is a requirement of the Android operating system to scan networks. 3> It’s also worth considering that some devices only work at 2.4GHz. If your router distributes 5GHz Wi-Fi and your phone is connected to it, the search for devices can go on for a long time or without success. In such cases, temporary switching to 2.4 GHz or using a mobile hotspot for initial setup helps. Data security and privacy The security issue when "sharing with the environment" is acute. By transmitting data about nearby devices, you are actually telling the application servers a list of equipment that is near you. This allows you to create a digital profile of the user: what kind of headphones he has, what kind of TV, even what model of car (via Bluetooth car system), Xiaomi says that the data is anonymized, but you should not rely on it completely. For maximum privacy, it is recommended to turn off Bluetooth and Wi-Fi when not in use, or use Device Visibility mode only when necessary. In Bluetooth settings, you can also turn off the display of the device name for everyone, leaving visibility only for the duration of pairing. What is it? MAC-Addressing and why it is important?MAC-The address is the unique identifier of the network interface. MAC-And the database of those addresses can tell you exactly where you're going, even without it. GPS. Android is changing periodically. MAC-scanner (MAC Randomization) for protection. Regularly checking the permission list is a good habit. Remove the applications you have stopped using, as they can continue to collect data in the background. MIUI There's a handy permission manager feature that shows you when the application accessed your data, which allows you to detect hidden activity (FAQ) Can you completely disable the “environmental sharing” on Xiaomi? Completely disable the system scanning function, as this will disrupt the Bluetooth and Wi-Fi modules. However, you can deny specific applications access to these features through privacy settings, leaving only system services? This happens if the app tries to run in the background and checks for devices regularly. For example, a fitness bracelet is constantly looking for a phone to sync. If this is annoying, check the battery settings for this application and limit background activity. Is it safe to allow location access for all applications? No, it reduces your privacy. Allow access to geolocation and network scanning only to those applications that really need it for work (maps, navigators, smart home, taxis). For others, it is better to choose the option "Only in use" or to ban it completely. Does this affect the speed of the Internet, if the Internet itself, the process of data is not affected by the speed of the Internet, if the data collection can be much? Usually, the amount of such data is minimal.
