Sharing with the environment in the Xiaomi phone: why you need and how to manage

Have you ever noticed the mysterious "Ambient Sharing" item in Xiaomi's settings and wondered what it does? It's a feature hidden deep in the parameters. MIUI, It's responsible for how your smartphone interacts with other devices and services around you, from wireless headphones to smart lights, but how it works, what data it transmits, and whether it can be turned off without affecting your phone?

In this article, we will discuss in detail what is an exchange with the environment in firmware MIUI, What technologies are behind it (including Mi Share, Quick Share and Xiaomi HyperOS Connect), and why the manufacturer turns it on by default.You'll also learn how to check what data your Redmi sends, POCO Xiaomi in the “environment” and how to minimize privacy risks – especially if you use your phone to handle sensitive information.

Spoiler: This feature is not as harmless as it seems. MIUI 15 HyperOS-based environment sharing can automatically geolocate to nearby Xiaomi devices to “improve the user experience” — and that’s just the tip of the iceberg. Next, a detailed guide with step-by-step instructions and a model compatibility table.

What is “intermediation sharing” in Xiaomi in simple words

The environment sharing feature (originally Environment Exchange or Nearby Share in global firmware) is a set of protocols that allow your Xiaomi smartphone to automatically interact with other gadgets nearby.

• 🔄 Synchronize settings between devices (for example, the theme or alarm clocks)
• 📱 Automatic connection to headphones, speakers or TVs Mi TV
• 📍 Geodata sharing for services like Mi Home or Xiaomi Cloud
• 🔗 Quickly transfer contacts or Wi-Fi passwords between Xiaomi phones

It is essentially an analogue of Apple Continuity or Google Nearby Share, but with specific features for the user. MIUI For example, in Xiaomi 13 Pro or Redmi Note 12, sharing with the surroundings can activate low-consumption mode on Xiaomi Buds headphones if the phone determines that you are at home (by geolocation and connected devices).

It's important to understand that this mechanism works continuously in the background, even if you're not transferring files. It scans nearby devices via Bluetooth. LE, Wi-Fi Direct and Ultrasound (in some models), while consuming up to 5-7% battery charge per day (according to tests on the POCO F5).

What technologies are behind the exchange with the environment

V MIUI And there's a whole range of technologies that are working in parallel, and these are the key ones:

The most voracious technology here is Geofencing, which constantly tracks your location to, for example, automatically turn on Driving Mode when you connect to Android Auto or turn off mobile data at home (if you have Wi-Fi). MIUI 14 and newer geofences work even when switched off GPS — The phone uses data from nearby Wi-Fi networks.

And here's Quick Share on the base. UWB (Available in flagships like Xiaomi 14 Ultra, this is a technology of the future that allows you to determine the distance to the device with an accuracy of 10 centimeters and will soon be used for contactless payments (like Apple Pay, but without the need to unlock the phone).

💡

If you notice that the phone is warming in your pocket for no apparent reason, check the Mi Share activity in the settings. Often background data transmission over Wi-Fi Direct leads to overheating of the processor.

How to check what data your Xiaomi is transmitting

To find out what data your smartphone is sending to the “environment”, follow the following steps:

1. Go to Settings. → Annexes → Permits → Interchange with environment.
2. Click on the Activity Log (available in MIUI 15 and newer).
3. Check the list of devices that have been exchanged in the last 7 days.
4. Tapping on any device to see the type of data transmitted (e.g. Contacts, Location, Wi-Fi settings).

Old versions. MIUI (14th) the activity log may not be available, in which case use the hidden menu of engineering settings:

#4636## → Phone information → Wi-Fi menu → Nearby Devices

This displays a list of all the devices your phone has interacted with via Bluetooth or Wi-Fi Direct, including the time of the last connection, Mi_:ab12:cd34), This may indicate an attempt to access unauthorizedly through vulnerabilities in the Mi Share protocol.

How to disable the exchange with the environment (in whole or in part)

If you're concerned about privacy or battery consumption, you can turn off the environment, either completely or selectively, and here are step-by-step instructions for different scenarios:

1. Complete shutdown of the function

This is a radical way to block all types of sharing, including file transfer via Mi Share:

1. Open the Settings. → Connections and sharing → Interchange with environment.
2. Move the slider to the off position.
3. Confirm the action in the dialog box (some firmware will need to enter a password from your Mi Account).

⚠️ Note: After that, you will not be able to use Quick Share to transfer files to other Xiaomi devices, and you will lose the automatic connection to headphones and speakers.

2. Selective disabling of individual protocols

If you want to keep some of the functions but limit the data transfer:

• 📴 Disable Wi-Fi Direct: Settings → Wi-Fi → Additionally. → Wi-Fi Direct → switch off.
• 📍 Disconnect geofences: Settings → Location. → geozones → remove all saved areas.
• 🔗 Banning the exchange of contacts: Settings → Annexes → Contacts → Permits → Interchange with environment → banish.

For example, if you turn off only Geofencing but leave Mi Share, you can transfer files, but the phone will stop automatically turning on Do Not Disturb mode at work.

Security: the risks of sharing with the environment and how to minimize them

The main problem with the environment sharing function is potential data breaches. In 2023, Kaspersky researchers discovered a vulnerability in the Mi Share protocol that allows attackers to:

• 📲 Intercept files when transferring if both devices are connected to the same Wi-Fi network.
• 📍 Tracking the user’s location via Bluetooth LE-lighthouse.
• 🔑 Switch data (for example, send a malicious file to your phone under the guise of a photo).

To protect yourself, follow these recommendations:

1. Update. MIUI until the last version, in MIUI 15 File Intercept vulnerability fixed.
2. Use it. VPN When transferring files via Mi Share on public networks.
3. Turn off automatic exchange for sensitive data (contacts, Wi-Fi passwords).
4. Check it out. MAC-address of devices before connection (they must match the specified on the gadget box).

⚠️ Note: If you use your phone to handle corporate data, disable all communication with your environment.In some companies (especially in the banking sector), data transfers via Mi Share or Quick Share may violate security policies.

💡

Even if you don’t hand over files manually, sharing with your surroundings can automatically send metadata (e.g., phone model, version). MIUI and geolocation) to Xiaomi servers to “improve services».

Interaction with the environment in different models Xiaomi: compatibility table

The functionality of the exchange with the environment depends on the phone model and version. MIUI. Below is a comparison table for popular devices:

Note: In budget models (e.g. Redmi) A2 or POCO C55) Sharing with the environment only works for basic file transfers through Mi Share. Functions like Quick Share or Geofencing are only available in mid- and premium devices.

It is also worth considering that in MIUI for the global market (for example, MIUI Global) some environment sharing functions may be disabled by default due to requirements GDPR (European data protection regulations in Chinese firmware (MIUI China) they are often on and do not have the option of a full shutdown.

Frequent problems and their solutions

Xiaomi users often face the following issues related to sharing with their environment:

1.The phone does not see other devices for file transfer

Causes and solutions:

• 🔋 Low battery (less than 15%) - Mi Share shuts down automatically.Solution: charge your phone or connect to the network.
• 📶 Incompatible versions MIUI — if on the same phone MIUI 15, and the other. MIUI 12, the exchange may not work. Solution: Update the firmware on both devices.
• 🔒 Firewall blocking – some antiviruses (e.g. Avast) block Wi-Fi Direct.Solution: add Mi Share to exceptions.

2. Bluetooth or Wi-Fi is constantly turned on

If you notice that Bluetooth or Wi-Fi is activated by themselves, it's the background exchange with the environment.

1. Go to Settings → Battery and Performance → Background Activity Management.
2. Find the Exchange with the environment and set a Strict Limit.
3. Turn off the Automatic Connection option in Mi Share settings.

3. The battery goes down fast.

If the charge has increased after the upgrade to MIUI 15, background scan of devices via Bluetooth is to blame LE. Decision:

• Turn off Device Search Nearby in Settings → Connections → Interchange with environment.
• Install the AccuBattery app and check which process consumes the most power (often com.miui.nearbyshare).

💡

If smart scripts in Mi Home stopped working after switching off the exchange with the environment, check the automatization settings - they may be tied to the geolocation or proximity of the devices.
