Xiaomi’s current smartphones, which run on MIUI or HyperOS shells, offer users enhanced telephony control. A feature known as call management combines not only a standard response to a call, but also a host of hidden settings, gestures and automations. Many device owners are unaware of how many useful options are hidden in the standard call interface, which by default seems simple and minimalistic.
Understanding what it is can greatly improve communication comfort: You can adjust the behavior of volume buttons during a conversation, activate the proximity sensor to automatically turn on the speakerphone or set up automatic recording of conversations. In this article, we will discuss all aspects of the phone module so that you can adapt the gadget to your habits.
The call management interface on Xiaomi often varies depending on the firmware version and region. However, the basic principles remain unchanged. Deep integration with system services allows you to implement scenarios that are not available on Android stock, for example, smart locking pocket mode or voice control driving are all part of a single ecosystem of call management.
The main functions and settings of the call interface
Basic setup starts with the main dial screen, where users are often confused by the huge number of options that Xiaomi kindly hides in the settings menu. Call management here involves customizing the appearance of the keyboard, font and order of display contacts. You can change the theme of the design or even set animated backgrounds for incoming calls if you use the appropriate themes from the store.
An important aspect is that you can set up contact searches, and it can search not only by name, but also by pinyin (a transcription of Chinese names) or phone number, and it works even if the contact is saved in +7 and you dial 8, and it automatically matches them, which is a critical part for those who are actively texting and calling from different numbers.
Keep in mind the integration with Mi and Google, and synchronizing your call history helps you keep important contacts in check when you change your device, but be careful: enabling cloud synchronization of your call history can lead to duplicate records if you use multiple SIM cards from different phones.
To access the advanced settings, you need to go to the three-dot menu and select Settings, and that's where the switches that control dial vibration, keystroke sound, and action confirmation are hidden. Turning off the keyboard sound may seem like a trifle, but in quiet rooms, it greatly improves the comfort of your smartphone.
Customize buttons and gestures during a conversation
One of the most embedded features in the control section is the physical button behavior setting. By default, the volume buttons adjust the sound level of the speaker or the conversation speaker. However, in call management settings, you can reassign their function. For example, a short tap can complete a call, which is incredibly convenient when your hands are in paint or you are wearing gloves.
Approximation Sensor is also available, and it's responsible for making the screen go out when you hold the phone to your ear. If this function is not working properly (the screen doesn't go out or goes out too early), you need to check the protective glass. Often, it's the thick glass that overrides the sensor located at the top of the case.
For users who often talk on speakerphone, the feature of automatically turning on the speaker when holding the phone to the ear in a certain position is useful, although on Xiaomi, the reverse logic is more common - turning on the speakerphone when removing the phone.
☑️ Checking button settings
There are also hidden gestures on the screen during a conversation, swiping your finger up or down can change volume, and swiping to the side can switch audio sources (Bluetooth, speaker, phone) and these functions can be disabled by default to save battery power or prevent accidental taps.
⚠️ Warning: Do not set too sensitive settings on the proximity sensor if you use a tight protective glass.This can cause you to be unable to press the screen while talking, as the phone will “think” it is near your ear.
Working with number detector and spam blocking
In today’s information noise, the issue of protection from unwanted calls is acute. Xiaomi has integrated powerful filtering tools that often work better than third-party applications. Call management uses cloud databases to identify spam numbers, ad agencies and scammers.
To activate the security, you need to go to the call settings and find the Antispam section, where you can enable blocking of hidden numbers, international calls (if you are not waiting for calls from abroad) and blacklisted numbers. The database updates automatically, but for the initial setup you may need to connect to Wi-Fi.
The number detector works on a database that users create, and if you get a call from a number that others label as "Pizza Delivery" or "Credit Department," your phone will alert you to that, and that allows you to not pick up the phone if you're not waiting for an order.
| Type of filtration | Description of action | Recommendation |
|---|---|---|
| Hidden numbers | Blocking calls without numbering | Turn on if you are not waiting for calls from the security services |
| International | Blocks codes from other countries | Include if there are no relatives abroad |
| Advertising/Spam | Blocks tagged numbers | Mandatory to inclusion |
| Blacklist | Blocking specific contacts | Used for personal conflicts |
It is important to note that blocking can be too aggressive, sometimes important calls from couriers or doctors can be labeled as spam incorrectly, so it is recommended to periodically check the log of blocked calls to avoid missing important information.

Automatic recording of conversations and confidentiality
One of the killer features of Xiaomi smartphones is the built-in conversation recording feature. Unlike many other manufacturers who are forced to abandon this feature due to US law, Xiaomi allows you to record with or without a notification of the interlocutor (depending on the firmware region), Call management here involves setting up the recording rules: record everything, only favorite contacts or only unknown numbers.
Records are stored in the device memory in format MP3 or AMR. You can find them through the Dictator app or in the file manager along the way. MIUI/sound_recorder/call_rec. This creates a convenient archive of all agreements, which is especially important for business and dispute resolution.
However, it is worth remembering the law. In some countries, recording a conversation without warning is prohibited. Xiaomi's system, when the recording is turned on, often emits a characteristic audible signal or a voice warning "Recording has begun" that the interlocutor hears, this is software difficult to get around, and attempts can lead to unstable system operation.
💡
To save space, set up automatic deletion of old conversation records over 30 days in the voice recorder settings.
Data privacy also plays a role: Recorded files are not encrypted by default and can be accessed by any application that has access to the file system. If you are storage information, it is recommended to transfer the records to secure folders or delete them immediately after use.
Additional features: Wi-Fi calls and VoLTE
Modern call management is impossible to imagine without VoLTE (Voice over LTE) and VoWiFi technologies, which allow you to make calls over 4G and Wi-Fi networks, respectively, providing high audio quality and fast dialing. On Xiaomi smartphones, these features are often enabled by default, but may require activation by the operator.
VoWiFi is especially useful in areas with poor cellular signal but good Wi-Fi. The phone will automatically switch to Wi-Fi to make a call, and the quality of the connection will be excellent.
To activate these functions, you need to go to the settings SIM-You'll find the "Use VoLTE" and "Wi-Fi Calls" switches there. If you don't have those, maybe you'll have to go to the office. SIM-The card is too old and needs to be replaced or the operator does not support these technologies in your area.
⚠️ Note: When using Wi-Fi (VoWiFi) calls, make sure you are in the same country where you are registered. SIM-In roaming, Wi-Fi calls can be charged as international, even if you are at home but connected to someone else's network.
Sound quality in HD-The format (which these technologies provide) is far superior to the standard format. GSM-The voice becomes natural, the metallic hues and the noise disappear, and it makes long conversations less tedious.
Solution: When the call is not working properly
Despite the system's cleverness, users sometimes run into problems: lost audio, not working speaker, or reset calls. Often the problem lies in a conflict of applications or a crowded cache of the telephony service, in which case call management requires resetting the settings of the phone application.
You go to the app settings, find the Phone (or Mi Dialer), and select Clear Cache and Clear Data, which won't delete your contacts (they're stored separately), but will return the call settings to factory settings, often solving problems with number identification or recording conversations.
If the problem is that the phone is not ringing or taking calls, check Do Not Disturb mode. In Xiaomi, this mode has advanced settings and can block all calls except favorite contacts, even if you forgot about it. It is also worth checking whether In-plane or 4G Only mode is enabled if there is no 4G coverage in your region.
💡
In 90% of cases, problems with calls to Xiaomi are solved by resetting the settings of the phone application or reconnecting SIM-map.
In rare cases, a complete reset of network settings may be required, which will remove stored Wi-Fi passwords and Bluetooth settings, but restore the communication modules to work correctly, only if other methods have not worked.
