Modern Xiaomi Redmi smartphones come with a variety of security features designed to help the wearer in a critical situation. One of these options is emergency call mode, activated by a quick press of the power button. While this feature can save lives, its accidental activation often leads to false calls to rescue services or contacts, causing unnecessary stress and confusion.
Many users experience a situation where a phone in a pocket or bag initiates a countdown to a call, due to the high sensitivity of the touch button or mechanical impact on the body. To avoid awkward situations and battery discharge with background calls, you need to know how to correctly manage this setting in the shell of MIUI or HyperOS.
In this article, we will discuss all the ways to deactivate SOS. We will look at standard system settings, emergency contact management and specific cases associated with regional versions of firmware, and understanding these mechanisms will allow you to fully control the behavior of your device.
The purpose and principle of operation of the emergency call
The SOS emergency call feature in Xiaomi smartphones is designed to instantly communicate with loved ones or life-threatening rescue services. The algorithm is simple: the user quickly presses the on/lock button five times, then starts the countdown. If it is not interrupted, the phone automatically dials pre-set numbers.
However, the mechanism has its own implementation features in different versions of the Android operating system and the manufacturer’s shells. In some cases, the system may require confirmation before a call, in others it may call instantly. False positives often occur when the phone is lying in a tight pocket of jeans or when the owner tries to quickly unlock the device with one hand.
Why can’t the function be completely shut down?
It is important to distinguish between the software SOS, which is configured through the menu, and the hardware features of the buttons. If the power button is physically stuck or has a defect, the software shutdown of the function may not help to eliminate the fact of recording clicks.
Disable SOS through the standard settings menu
The easiest and safest way to remove automatic dialing is to use the built-in settings interface, and the path to this menu may vary slightly depending on the version of MIUI, but the logic remains the same. You need to go to the section in charge of security and emergency.
☑️ Action algorithm on the menu
To start, open the Settings app and search at the top of the screen. Enter "SOS" or "Emergency." The system will provide the menu item you want. If the search doesn't yield results, manually search in the "Passwords and Security" or "Security and Emergency" categories.
Inside the section, you will see the SOS Emergency Call switch, turn it to Off. Note that there may be additional options below, such as Send Location or Turn on Recorder, which are also recommended to be deactivated if you do not plan to use the feature in the future.
⚠️ Warning: After disabling the function in the settings menu, be sure to test press the power button 5 times to make sure the countdown no longer appears. In some software builds, settings may be reset after the system update.
Management of emergency contact
Even if the quick call mechanism is active, it can't make a call without the designated recipients. Deleting or changing the contact list is an effective way to neutralize the feature without shutting down the security system itself completely. This can be useful if you want to keep the feature active for yourself, but exclude calls to outsiders.
Go to the emergency contacts menu (usually the same as the SOS settings). Here you will see a list of people to whom the signal will be sent. Click on the contact and select the option Delete or Remove. If the list is empty, the phone may try to call the standard emergency numbers (112, 911), depending on the region of the SIM card.
- 📞 Remove all added personal numbers from the trusted contact list.
- 🔒 Check if the check box is on the "Call the police" or similar item.
- 📵 Make sure that the SIM card is not set to automatically dial in the absence of contacts.
Therefore, the complete disappearance of the Emergency Call button from the lock screen may be impossible and undesirable from a security point of view.
Locking the power button and preventing false positives
A common reason for activating SOS is not the user's desire, but the random pressure on the button. There are settings in the MIUI shell to ignore the pressing in the pocket, but they don't always work perfectly. An additional measure may be a change in sensitivity or the use of a case.
There is also a "Mode in your pocket" feature that locks the screen and sensor when the proximity sensor is in the dark. Make sure it's enabled in Settings → Lock screen. This will help prevent accidental tapping when the phone is in the bag along with other items.
If the power button is on the side of the side and has a short stroke, the risk of accidental pressing increases. In such cases, users sometimes resort to installing specialized button-blocking applications, although this can complicate the devices. A more reliable method is the use of a high-sided protective cover that physically restricts access to the button.
Specificity of Chinese versions of firmware (CN ROM)
Smartphone owners imported from China often face more aggressive security implementations. In Chinese firmware versions (CN ROM), the SOS menu can be integrated into the Security system app (green shield icon) rather than the general Android settings.
To find settings in CN ROM, open the Security app. Scroll down to Emergency SOS or Emergency Call. Here the interface can be entirely in Chinese, so focus on icons and item locations. It's usually the fifth or sixth item on the list.
| Parameter | Global version (Global) | Chinese version (CN) | European version (EEA) |
|---|---|---|---|
| Location of the menu | Settings → Passwords and security | Security Annex | Settings → Security |
| Sound alert | Customizable | Often forced | Customizable |
| Sending SMS | Optionally. | Built into the system | Optionally. |
| Interface language | Russian/English | Chinese/English | Multilingual |
If you can't find the settings because of the language barrier, use the image translator or install the Russifier if the phone model allows it.Full flashing on the Global ROM can fix the problem with the incomprehensible interface, but requires unlocking the bootloader.
Solving freeze problems and software failures
Sometimes the SOS function does not turn off due to a software failure or conflict of system processes.The phone can continue to respond to a five-push button even after you have moved the switch to the off position.
Try resetting your special features. Go to Settings → Advanced Settings → Special features. Check which services are active. Sometimes third-party apps requesting access to buttons can intercept control and ignore SOS system bans.
⚠️ Attention: If the function is disabled SOS It doesn't help and the phone keeps behaving inappropriately (spontaneous switching on, heating), maybe the problem lies in the plume of the power button.
Also effective is cleaning the cache of the Phone and Contacts system app. Go to Settings → Apps → All apps, find the system call apps and click Clear Cache. Don't confuse it with Clear Data, as this can delete your call history.
💡
Check system updates periodically. Xiaomi often releases patches that fix bugs with button sensitivity and emergency services in new versions of MIUI.
The Impact of Android Updates on Security Settings
With the release of new versions of Android (12, 13, 14 et al.), Google is tightening security requirements, SOS settings can move from one menu to another or change their name. For example, Android 12 has an Emergency Data Access feature, which also involves unlocking your phone in a critical situation.
After a major firmware update, always recheck your emergency call settings, and the system may have reset your preferences to standard ones for user safety, especially when switching from MIUI 12 to MIUI 13/14 or HyperOS.
- 🔄 After the update, check the section "Security and emergency».
- 📱 Make sure new features, such as Medical Information, don’t conflict with the health care system. SOS.
- 🔔 Check notifications: sometimes the system insists on enabling SOS post-update.
Users should understand that it is impossible to completely cut out the system code responsible for emergency calls without violating the integrity of the operating system. All available methods are aimed only at disabling automation and convenient access, but not at removing the very possibility of calling rescue services, which is a certification requirement.
💡
Complete removal of SOS is impossible without root rights, but disabling auto dial and audio signals completely solves the problem of false positives.
