Modern Xiaomi Redmi smartphones come with a variety of smart features designed to make it easier to control the device, one of which is voice control, which allows you to make calls and run applications without touching the screen. However, many users face a situation where the phone begins to “live its life” and make calls on a voice command or simply because of the accidental touch of the cheek during a conversation.
The problem can be different MIUI settings, from the built-in Google Assistant to specific features of Xiaomi’s shell, such as Voice Control in the Phone app. Often users do not understand which mechanism is activating the dial, and start to panic, believing that the device is infected with a virus or malfunction, in fact, these are only the wrong settings of accessibility or calls.
In this article, we will take a look at all the possible ways to remove a voice call on Xiaomi Redmi.We will go through the system settings, check the call app and look at third-party applications that can interfere with the communication process. Careful implementation of each step will help you forget about random calls and regain full control of your gadget.
Diagnosis: Why does the phone ring by itself?
Before you start disabling functions, you need to understand the nature of voice calls. In Redmi devices, it can be responsible for not one, but several services. Most often, the culprit is the Voice Dialing function, which is activated when you raise the phone to the ear or voice command, and the source of the problem can be special settings designed for people with disabilities, but turned on by mistake.
Another common cause is the so-called pocket dial, where the proximity sensor can become dirty or malfunction, which causes the screen to react to touches inside the pocket, in which case the phone perceives random taps as a command to call the last number or number on the contact list, and false alarms of sensors are a common problem that is easy to solve by software.
And the impact of third-party apps is not excluded: the voice recorders you install, the voice assistants from third parties, or even some messengers can request access to the microphone and the phone book. If the smart dial application is running in the background, it can initiate a call. So a comprehensive diagnostic approach involves checking not only system settings, but also a list of installed programs.
Disabling voice dialing in the Phone application
The most likely source of the problem is in the standard calling app. In the MIUI shell, it has its own settings that can override the system. First, open the Phone app (green handset) and tap three dots or a gear in the corner of the screen to enter the settings menu. Here we are interested in the section related to incoming calls or voice control.
In the menu that opens, find a item that may be called Voice Dialing or Voice Dialing. Depending on the MIUI version and regional firmware (Global, China, EU), this option may be in the Advanced Settings subsection or be entered in the main menu. Deactivating this switch will prevent the phone from responding to voice commands to make calls through a standard call.
Also in this section, you should pay attention to the Voice Response feature, if it is enabled, the phone can drop calls or take them on your command, which is sometimes interpreted by the system as active voice control. Make sure that all options associated with non-touch call management are turned off. This is guaranteed to fix the problem if it is caused by standard software.
☑️ Checking the call settings
Setting up Google Assistant and Google Voice
The second most popular culprit is the Google ecosystem. Google Assistant is deeply integrated into Android and can be activated by saying "OK, Google" or "Hey Google." If the assistant's settings allow making calls, any similar phrase spoken next to the phone can lead to dialing, and to remove this feature, you need to go to the assistant's settings.
Open Google settings on your phone, select “Settings for Google Apps” and search for “Google Assistant.” Go to “Phone” or “Devices.” You should turn off the “Allow Personal Results” option or specifically prevent the assistant from making calls. It is also recommended to turn off the “Clocked Screen Access” function so that the phone does not respond to voice commands when it is in your bag pocket.
Pay special attention to the Google Voice app if installed. It's a separate call service that has its own voice control settings. If you don't use it, you can turn it off or uninstall it to avoid conflict. Often, it's the intersection of standard calling and Google services that creates confusion.
⚠️ Attention: After system update MIUI Privacy settings can reset to factory settings. Be sure to recheck the permissions for Google Assistant after each major firmware update so that the voice dialing feature doesn't activate again.
Special Opportunities Management (Accessibility)
Deep in the Android system settings, there’s an Accessibility section that’s designed to help people with visual or motor impairments, but its features often cause random smartphone behavior among ordinary users, and there may be services that read the contents of the screen and respond to voice commands or gestures.
Follow Settings → Advanced Settings → Special Features. Carefully review the list of services enabled. You should be interested in items like Voice Access, TalkBack, or Touch Choice. If you see Voice Access active, it allows you to control your phone with voice, including calls. Click on it and select "Stop" or "Delete."
In addition, this section has a "Look Control" or "Head Control" setting that can also be accidentally enabled. Disable any services that have the words "Voice", "Voice", "Sound" or "Touchless Control" in their name or description, which will free up system resources and prevent accidental activation of call functions.
What is Voice Access and should it be removed?
Disabling the function “pocket mode” and sensors
Pocket mode is designed to prevent accidental taps when the phone is in your pocket, but on some Redmi models, it doesn’t work properly and locks the proximity sensor, causing the screen to react to friction like finger-touching, often resulting in the emergency number or last contact being dialed in your pocket.
To check and configure this feature, go to Settings → Lock and Protection → Pocket Mode. Try to turn this option off completely. If the sensor sensitivity was a problem, the calls should stop. It is also worth checking the proximity sensor settings, although there is no separate calibration menu in MIUI, you can use the engineering menu.
To enter the engineering menu, dial ##6484## in the call. In the test menu that opens, select Proximity sensor. Close the top of the screen with your hand and remove it, the values should change from 5.0 to 0.0. If the values do not change or jump, you may need hardware repair or replacement of the protective glass that covers the sensor.
| Function/Service | Wherever | Risk of accidental call | Recommendation |
|---|---|---|---|
| Voice dial (Caller) | Appendix Phone → Settings | High-pitched | Shut down. |
| Google Assistant | Google's Settings → Assistant | Medium. | Restrict access with a lock |
| Voice Access | Special opportunities | critical | Remove or turn off |
| Pocket regime | Settings → Blocking | Medium. | Test (On/Off) |
Verification of third-party applications and conflicts
If the system settings are in order, the reason may lie in third-party software: applications for recording calls, smart contacts, number detectors, or even miner viruses can use system vulnerabilities to make calls, remember whether you recently installed new programs before the problem began.
Go to Settings → Apps → All apps and look carefully at the list. Look for apps with suspicious names or ones you don’t remember installing. Pay special attention to programs that have permission to access Microphone and Phone. If you find an application that is not system-based but requires such rights, you better uninstall it.
It's also worth checking autoboot. Some programs are prescribed to autorun and start working immediately after the phone is turned on. MIUI has an antivirus and an optimizer built in. Run a security check to rule out malware. Often hidden miners are disguised as system processes, but they can be calculated at high battery consumption.
💡
Periodically check the list of applications with access to the microphone. Go to Settings → Privacy → Permission Manager → Microphone. If you see a flashlight or calculator app there, immediately take it away.
Resetting and radical measures
In situations where none of the above methods worked, there may be software errors or configuration file conflicts in the system, in which case resetting application settings or completely resetting to factory settings can help. Be sure to back up all important data before doing so, as if completely reset, it will be deleted.
Try starting with a less radical method: reset the Phone and Contacts app settings. Go to Settings → Apps → All Apps → Phone → Memory and click Clear → All Data. This will return the call to its original state by deleting the history and settings, but will not affect your contacts and photos.
If that doesn't work, then the last option is a full reset. <
