Xiaomi’s smartphone today is not just a communication device, it’s a powerful personal security tool. In a critical situation, when the count goes on for seconds, access to emergency functions should be instant, and for such cases, the MIUI and HyperOS shell have a special SOS mode that allows you to send a distress signal at the touch of a button.
Many users are unaware that their phone can automatically send location coordinates and audio recordings to trusted contacts, and understanding how this feature works can save your life or your loved ones in an emergency.
In this guide, we will take a closer look at the algorithm for activating, configuring, and working intricacies of the Redmi and Poco emergency alarm system, and learn how to avoid false positives and ensure that the signal is sent even when the screen is locked.
The principle of operation of emergency call
The SOS feature on Xiaomi smartphones is built on a simple but effective mechanical trigger, based on a five-fold press of the power button (lock) for a short period of time, which forcefully activates an emergency call or message, bypassing the need to unlock the screen or search for contacts.
Once the trigger is activated, the phone may behave differently depending on your settings, the device can automatically dial the rescue number (112 or 911) or send pre-prepared ones. SMS-geolocated messages to trusted numbers. GPS-Internet connection on the recipient’s phone is not required – coordinates are transmitted in the form of a text link or coordinate grid.
⚠️ Note: When activating the mode SOS The phone can make a loud beep that cannot be silenced by conventional volume buttons, which is designed to attract the attention of others, but can frighten the owner in a quiet environment.
The MIUI security system also allows automatic audio recording, and if this option is enabled, the smartphone will start recording audio from the microphone immediately after five taps of the power button, which is then attached to the message or stored in internal memory, which can serve as important evidence in the future.
💡
Five-time pressing of the power button is a universal standard for activating SOS on Android, working even on a locked screen without the Internet (for a call).
Step-by-step setting up the security function
To work properly, it must be pre-activated and configured in the system menu. the interface may vary slightly depending on the version of the shell, but the logic remains the same for all Xiaomi, Redmi and Poco models.
To start, open the standard Security app (green shield icon) that is preinstalled on each device. At the bottom of the screen, find and click on the SOS tab. If you’re using the new version of HyperOS, the path may lie through Settings → Passwords & Security → SOS Emergency Call.
☑️ Set-up of the regime SOS
Once you log in, you'll be asked to switch on the function, the system will request confirmation of your actions, warning you of possible costs, then add contacts that will receive alarms, you can select up to four numbers from the phone book or enter them manually.
Pay special attention to setting up a text message, which is the default template, but it is recommended to add important information, such as blood type or chronic diseases, to help rescuers or friends navigate the situation faster.
Contact and communication management
The effectiveness of SOS depends on the correctness of filling in the contact list. In the settings menu, you can add, delete or edit numbers. It is important to choose people who are guaranteed to answer the call or see the message at any time of the day.
The text can be edited to suit your needs, and you can write, "I need help, I'm in danger. My coordinates: [link]." Some versions of the shell allow you to attach to the message not only text, but also a photo taken by the front camera at the time of activation, which helps to identify the situation.
- 📍 Geolocation: Automatically adds a link to a map with the exact location of the device at the time of clicking the buttons.
- 🔊 Audio: Option allows you to send a 5-second recording of the surrounding sound so that the recipient understands the context of what is happening.
- 📸 Photo Fact: Some Xiaomi models have a feature of hidden shooting on the front camera when activated SOS.
Remember to check the number time every once in a while, if the contact changes phone number or SIM card, the message may not reach, and make sure that the selected people have your number stored so they can call back quickly.

Fine tuning and additional options
The MIUI shell offers a number of advanced settings that make using the feature more flexible. For example, you can adjust the delay before sending a message. This is a useful feature to prevent random signal sending if you just played with the lock button in your pocket.
The option “Alarm Sound” is often found in the additional settings section, and if activated, the phone will make a piercing sound when SOS is activated. This can scare off the attacker or attract the attention of passers-by, but in some situations (such as hostage-taking), this can be dangerous.
| Parameter | Description of function | Recommendation |
|---|---|---|
| Delayed shipment | Time (3-5 seconds) before sending after 5 presses | Leave it on to avoid false positives |
| The sound of alarm | Loud signal when activating the mode | Turn on for street safety, turn off for stealth |
| Auto-answer. | Automatic response to incoming call from a trusted person | Turn on if there is a risk that you will not be able to pick up the phone |
| Sound recording | Automatic recording of audio environment | Include for evidence collection |
You should also pay attention to the automatic response function, which if you set it up, when you call from a trusted contact (from the SOS list), the phone can automatically reset the call or, conversely, accept it and turn on speaker, allowing the interlocutor to hear what is happening around you.
False positives and how to avoid them
One of the most common problems Xiaomi users have is accidentally activating SOS in their pocket or bag. Five taps is not much, and tightly fitting the fabric to the power button can trigger a trigger, which leads to battery drain, sending false signals to friends and unnecessary calls to emergency services.
To minimize the risks, use a smart lock or a case with a protective frame that protrudes slightly above the buttons. In the settings, you can also increase the time interval during which five clicks must be made, although standard Xiaomi firmware does not always give this flexibility.
⚠️ Note: If you accidentally activate SOS, Pick up the phone immediately if a call comes from the operator, or send an explanatory message to contacts on the list so they don't call the police.
There's another caveat: some protective glass or thick covers can actually interfere with pressing. In an emergency, when your hands are shaking or gloves are putting on, it can be difficult to hit the little button five times.
Features of work in different versions of MIUI and HyperOS
The interface and availability of features can vary. On older versions of MIUI 10-11, the SOS menu was exclusively in the Security app. In newer versions (MIUI 12, 13, 14) and especially in HyperOS, Google is actively integrating its security standards, sometimes duplicating or replacing Xiaomi's features with its own Personal Security service.
Recent updates have included the Emergency Access feature, which allows medics or rescuers to access your medical records and contacts without unlocking your phone.It's a separate feature, but it's closely tied to the overall safety concept.
- 📱 MIUI 12-13: Classic menu in the Security app, full control over text and sound.
- 🚀 MIUI 14 / HyperOS: Integration with Google Personal Safety, customization via Google Play Services.
- 🌍 Global version: May differ from Chinese firmware by the presence or absence of some audio recording options.
If you upgrade to the latest version of the system and don’t find the usual settings, check the Passwords and Security section in the phone’s main settings. Google is gradually bringing these features to the Android system core, making them independent of the manufacturer’s shell.
💡
Add medical information (allergies, blood type) to the Medical Card section in the screen lock settings, which you can see without unlocking your phone and can save lives even if the SOS mode has not been activated.
