Why does my Xiaomi mobile phone have three security tips, such as private SMS lock, every time it receives SMS? No settings were found in the private SMS lock.

If multiple programs are installed on the mobile phone, SMS will be monitored by multiple programs and prompted separately. For example, every time I accept a short message here, sometimes it will be intercepted by Jinshan mobile guards and prompted as spam, and sometimes it will be intercepted by Tencent mobile housekeeper and prompted as spam. Sometimes I will be prompted to receive short messages by Ka Niu, Ka Li SMS and the SMS program that comes with my mobile phone. Some programs don't provide settings, and some are troublesome even if they are set.

In my experience, when I actually use it, I just need to install a full-featured mobile phone housekeeper or something, and other programs for filtering short messages have been deleted.
