However, sometimes it blocks important emails or contacts, interferes with messengers and even restricts access to corporate services. If you encounter such a problem, this article will help you understand how to properly disable antispam on various Xiaomi devices, from smartphones to smart TVs.

It is important to understand that disabling spam protection can lead to an increase in unwanted messages and calls. In some cases, it also affects the operation of built-in security services such as Mi Security or Google Play Protect. We will discuss in detail all possible ways, from standard settings to hidden settings, and explain the risks associated with full deactivation of antispam.
