Xiaomi smartphones come with a variety of useful features, one of which is emergency call for rescue services. On the Redmi Note 7, this option is activated by a quick press of the power button, which in everyday use often leads to random calls. Users often face a situation where the phone in their pocket or bag begins to dial the emergency number, causing confusion among the owner and unnecessary burden on operators.
The problem is relevant for the MIUI shell, where security settings take precedence over normal activities. To avoid false positives, you need to configure system settings correctly. In this guide, we will discuss all available methods for deactivating the function, and also consider the nuances of working with emergency contacts.
Sometimes, a standard shutdown through the menu doesn't help, and the phone continues to respond to clicks, which may be due to software failures or features of the firmware version. Understanding the mechanism of Emergency SOS will allow you to fully control the behavior of your device in critical situations.
Emergency call mechanism in MIUI
The Xiaomi emergency call feature is designed for situations where the user cannot unlock the screen. The algorithm is simple: pressing the power button five times in a short period of time initiates a call. The system ignores the screen lock and immediately goes to dial. This is a critical security feature, but its sensitivity often causes problems.
The work is based on a system service that tracks the state of the power button even in sleep mode. When a certain pattern of clicks is fixed, the corresponding script is triggered. On the Redmi Note 7, this process is optimized, but sometimes the physical wear of the button or the protective case can provoke false positives.
⚠️ Warning: Disabling the feature completely may deprive you of a quick way to contact rescuers in a real emergency situation.It is recommended that instead of turning off, simply change settings or delete numbers.
It’s worth noting that settings may vary slightly across Android and MIUI shells, but the logic remains the same across the brand ecosystem, and understanding this principle will help you navigate the menu even after you upgrade.
The main way to disconnect through security settings
The easiest and most reliable method of deactivation is to use the regular settings menu, which does not require root rights or third-party software installation, but you need access to the security section, where all the parameters associated with emergency situations are concentrated.
To start, unlock your Redmi Note 7 screen and find the Security app, which has a green icon with a shield and is usually located in the Tools folder or on the home screen, and there are many important system utilities hidden inside this app.
- 📱 Open the Security app and scroll down to the Tools section".
- 🔍 Find the icon. SOS or item "Emergency call" SOS" listing.
- 🚫 Switch the slider to the "Off" position to completely deactivate the function.
Once you do this, the phone will stop responding to the five-fold press of the power button, but if you want to keep the function active but change its behavior, you can adjust the delay or number of clicks, if this option is available in your firmware version.
☑️ Checking settings SOS
Removal and editing of emergency contacts
Even if the call mechanism is active, it can't make a call without a designated recipient. In the MIUI settings, you can specify up to three contacts that will receive the alarm, and removing those numbers actually makes the function useless even if it's on.
Go to Settings menu → Passwords and Security → Emergency SOS call. Here you will see a list of added contacts. Click on the number you want to delete and select the option to delete or edit. An empty list of contacts will prevent the call from being made.
| Parameter | Description | Recommended value |
|---|---|---|
| Contacts | Call numbers. | Empty or trusted |
| SOS message | Text SMS when calling | Disconnected. |
| The alarm sound | Loud sound when activated | Off. |
| Automatic call. | Call after countdown | Off. |
The editing of the list only concerns personal emergency contacts.

Setting the behavior of the power button

Go to Settings → More → Buttons. You can set up the action here with double pressing or long-term retention. While this does not turn off SOS directly, changing the sensitivity or assigning other actions (such as launching the camera) can reduce the frequency of false positives.
If the power button is physically worn out and sticks, the software shutdown of SOS becomes the only option, in which case the system can interpret the vibrations of the button as a command to action. Consider replacing the button in the service center if the problem is hardware-related.
⚠️ Attention: Changing the settings of the power button may affect other features, such as alarm clock or voice assistant. Check all assigned actions after the changes. 9> For users who often wear a phone without a cover, it is recommended to use a protective film on a button or a case with protruding sides.
