When your smartphone suddenly starts buzzing and connecting a call without touching the screen, it can take anyone by surprise, especially when the device is in your pocket or on your desk, and you don't even have time to see who the caller is calling. Users often panic, believing that the phone is infected with a virus or has been hacked, but in 99% of cases the reason lies in the regular, but incorrectly configured features of the MIUI system.
The main culprits for this behavior are usually built-in assistants, gesture controls, or specific accessibility settings. The system can interpret random movements or sounds as a call command. To regain control of its device, you need to consistently check several menu sections, since the location of the switches may vary depending on the firmware version.
In this guide, we’ll take a look at all the possible scenarios that Xiaomi is responding to, and provide clear instructions on how to deactivate them, and learn how to set up a proximity sensor, disable voice commands, and remove unnecessary actions when touching the screen to avoid embarrassing situations in the future.
The function “Raise for response” and sensors
One of the most common reasons the phone picks up the phone is because it activates gesture response, which is designed for convenience: when you lift the device to your ear during an incoming call, it automatically connects the caller, but the proximity sensor or accelerometer may not work properly, responding to vibration or change of position in the bag.
To check and disable this option, you need to go to the standard Phone app, which is the default dialer in the MIUI shell. Next, click on the three dots in the upper right corner (or the settings button) and select Settings. In the menu that opens, look for the Incoming Calls section.
Inside this section is a "Gestural Answer" or "Raise to Answer" switch, and if it's active, the system will try to connect the call whenever the device moves like a head-mounting motion, and turning it off will completely eliminate the response to the physical movements of the smartphone.
⚠️ Warning: After disabling the “Raise to Answer” function, you will have to manually press the call button on the screen every time, even if you hold the phone to your ear.
💡
If the proximity sensor is contaminated or closed with a protective film, the "Raise to Answer" function can be triggered chaoticly.
Voice control settings and Assistant
The second likely reason for automatic response is voice control. Xiaomi and Redmi phones often activate a feature that allows you to receive calls with a voice command "Respond" or "Hello" This is convenient while driving, but in a quiet environment or when talking near the phone can lead to accidental activation.
To disable this option, go to the Settings menu of the Phone app itself. Find the Voice Control section (sometimes inside the Inbox Settings section). Here you will see the Voice Response option. If the slider is blue, the phone is responding to voice commands.
It’s also worth checking the settings of Google Assistant if it’s used as the primary assistant. Sometimes it’s third-party services that intercept call management. In the Google Assistant settings, you need to find the Phone section and make sure that it doesn’t have automatic actions for incoming calls.
- 🗣️ Open the Phone app and go to settings via the menu.
- 🔊 Find the "Voice Control" and deaktivirujte (turn off) answer option.
- 🤖 Check the Google Assistant settings for call automation.
- 📞 Make sure the Caller Name Voice function does not conflict with voice control.
☑️ Verification of voice functions
In your pocket mode and casual touches
Mode in Pocket is designed to lock the screen when the smartphone is in a closed space to prevent accidental tapping. However, paradoxically, this protection sometimes causes Xiaomi to answer calls itself. With a poor calibration of the light sensor, the phone may “think” it is in your pocket, and then, when vibrating, mistakenly register the touch through the fabric as a command.
Control of this mode is in the general settings of the system. The path to it: Settings → Screen → Mode in your pocket. If the switch is active, try to turn it off and test the behavior of the device. In some versions of MIUI, this item may be called "Block in your pocket."
Also, you should pay attention to the sensitivity of the screen, because if you have a thick protective glass on your device or you use a poor quality film, it can affect the touch screen, and in such cases, the phone can react to the pressure of the tissue in your pocket as a full touch of the finger.
⚠️ Warning: Turning off the mode in your pocket increases the risk of accidental calls to contacts from the quick dial list if the phone is lying screen down in your bag.
It is also recommended to check whether the feature is included in the special features section, which is designed for people with poor vision and is activated by a triple tap, but can sometimes conflict with the call interface.
Third-party applications and software conflicts
If the system settings are in order, the problem may be hidden in third-party software. Various applications for number detection, recording conversations or improving sound may request permission to manage calls. After updating the firmware, such programs may not work correctly, causing a spontaneous reset of the tube.
First, check newly installed programs. Pay particular attention to callers from other manufacturers (like Truecaller, Numbr) or voice recorders. Try temporarily removing them or revoking permissions in the Settings menu → Apps → Application Management.
It’s also worth checking for updates to the Phone app itself and Google Play services. Sometimes a bug in a particular version of the software causes the problem described, and developers release the patch pretty quickly.

Comparison of methods of disabling autoresponse
For the convenience of users, we have prepared a summary table that will help you quickly determine which method of solving the problem will suit you. Different models Xiaomi and Redmi may have slight differences in the interface, but the logic of the functions remains the same.
| The cause of the problem | Where to look for settings | Difficulty | Risk of side effects |
|---|---|---|---|
| "Raise for an answer" gesture | Phone. → Settings → Incoming | Low. | You need to press the button manually. |
| Voice control | Phone. → Settings → Voice response | Low. | Inability to respond with a voice |
| Pocket mode. | Settings → Screen | Medium | Accidental taps in the bag |
| Third-party annexes | Settings → Applications | Tall. | Loss of application functionality |
As you can see from the table, most solutions are in the surface layers of the menu and do not require deep intervention, but if none of the methods worked, a more radical approach, involving resetting or flashing, may be needed.
Diagnostics of hardware problems
In the rare cases where software methods are powerless, a physical malfunction may be the cause. If the touchscreen has micro-damage or the display plume is damaged, the device can register phantom taps in the area of the response button, often after falls or moisture.
You can check the screen using the engineering menu. Type ##6484### (or #4636## for some models) in the call. Select Touchpanel or Display and run a uniformity test. If the screen is buggy in certain areas, you can't program that.
Also worth noting is the charger: Cheap power supplies can interfere with the phone's power grid, leading to chaotic touchscreen behavior while charging, and if the phone only answers calls on charge, replace the cable or the unit.
⚠️ Warning: If the screen is broken or cracked, the phone may not be safe to use, glass shards may damage your finger, and a short circuit may permanently disable the device.!
💡
If the tests show that the screen is working, but the problem persists, try to perform a full reset (Hard Reset), pre-saving important data.
