The modern smartphone has long since ceased to be a mere means of communication, becoming a central node of the digital life of the user. However, the basic voice call function remains critical for millions of owners of Xiaomi devices. MIUI, which is an add-on to Android, offers an advanced toolkit for filtering incoming signals, which is often hidden from the eyes of the average user in the depth of the menu. Understanding how Xiaomi calls work allows you not only to weed out spam, but also to correctly distribute work and personal contacts, creating a personalized communication environment.
Owners of the Chinese giant’s devices often face the need to fine-tune communication settings immediately after purchase. Standard settings may seem excessive or, conversely, insufficient without deep immersion in system options. Proper use of locking, redirecting and anonymizer functions can significantly improve the level of digital comfort. In this article, we will examine in detail all aspects of working with telephony on Xiaomi smartphones, from basic settings to advanced methods of protection from unwanted noise.
It is worth paying special attention to the fact that the algorithms for working with calls can vary depending on the version of the operating system and regional firmware. Global versions of MIUI and Chinese builds have differences in the interface and available features. So it is important to understand the general principles of the communication module to successfully adapt them to your specific device model, whether it is a budget Redmi or flagship Xiaomi.
Basic navigation and call interface
The first step to full control of incoming and outgoing connections is to master the interface of the standard Phone application. In the Xiaomi ecosystem, this component is often based on the Google Dialer engine or its own MIUI Dialer solution, depending on the year of release of the device and the region. To access advanced settings, you need to go to a menu, which is usually indicated by three dots or a gear in the corner of the call screen. This is where the Settings item hides, which allows you to control the behavior of the system when the signal arrives.
Inside the settings menu, the user discovers the separation of functions into logical groups, and you can find options for working with the number detector, setting up quick dialing and control (call log). An important element is the ability to adjust the behavior of the smartphone during a conversation: turn on the proximity sensor that turns off the screen when you lift it to the ear, or change the volume of the call in your pocket, these features prevent accidental pressing and provide a comfortable communication.
Note that the visual design of the menu can vary, new versions of HyperOS tend to be minimalist, with secondary functions removed from the submenu, but key controls such as locking and redirecting are always available in the main list of parameters, understanding the structure of this menu is the basis for further customization of security and usability of the device.
Functions of blocking unwanted calls
One of the most popular features in modern smartphones is spam and telemarketing protection. Xiaomi calls management includes a powerful built-in filtering mechanism that works at the system level. To activate it, you need to go to the Settings section of the phone application and select Lock, where the user can turn on the Antispam mode, which automatically identifies and sifts out suspicious numbers using updated databases.
The system allows you to create flexible filtering rules, you can block all calls from hidden numbers, which is especially true for those who often encounter scammers using anonymizers, and you can also block all incoming contacts except from the phone book, which is the ideal mode for vacation or work, when you need to focus and not be distracted by extraneous signals.

In addition, you can create a manual blacklist, if you're constantly concerned about a particular number, you can add it to the list of prohibited numbers, not only will the system ignore the call, but it can send a busy or reset call without notifying the subscriber, depending on the settings you choose, and the lock log is kept separately, allowing you to see who tried to reach you if necessary.
☑️ Setting up protection against spam
Set up redirection and redirection
Redirection is a tool that allows you to redirect an incoming call to another phone number. This feature is useful in situations where you are outside the access zone of your main operator's network or are roaming where incoming charges are paid. In the Xiaomi call management menu, this section is often called Additional Settings or Redirection. The system offers several redirection scenarios: always when busy, when not picking up, or when not available.
To activate the function, you need to enter the number to which the calls will be received. So, before turning on, you should specify the tariff conditions. In the MIUI interface, the redirect status is displayed by an icon in the status bar or in the notification curtain, which allows you to always keep in control where your calls go.

Hiding the number and identification of the caller ID
The privacy issue of outbound calls is addressed through the Hiding Number feature. Xiaomi calls have an option called Additional Settings → Display Number. Here, the user is offered three options: show the number, hide the number or use the default network settings. This feature is useful when calling support services or contacting unfamiliar counterparties when you do not want to leave your personal contact.
On the other hand, incoming calls are supported by Caller ID. Xiaomi smartphones are actively using databases to identify the caller’s name, even if it is not in your contacts. This can be the name of the organization, the delivery service, and the data for this function can be downloaded through Google services or built-in MIUI services (depending on the region).
Consider that the carrier may block the possibility of hiding the number on the tariff plan, in which case, even if you choose the option "Hide the number" in the phone menu, the subscriber will still see your number. You can only test this possibility by calling another phone. If the hiding does not work, you need to contact your carrier to clarify the pricing conditions.

Recording conversations and managing history
The built-in conversation recorder is one of the most popular features among Xiaomi users. Unlike many other smartphones, it can be recorded automatically for all numbers or selectively. The setup is located in the Call Record menu. You can set the system to record only numbers from the phone book or, conversely, only for unknown numbers. It is a powerful tool for monitoring and storing important information.
