If you are faced with the fact that MIUI aggressively filters incoming data, this manual will help to regain control of communication.

Open the Security app and go to Antispam, where you will see three main blocks:

• 📞 Protection against spam calls – filtering incoming calls
• 💬 Spam protection-SMS — blocking
• ☁️ Cloud database – synchronization with Xiaomi servers

All three switches must be deactivated to completely shut down, but even then some functions may remain active at the system level, for example, if you previously blacklisted numbers manually, they will be blocked regardless of the anti-spam.
