Why do you receive all-black text messages from strangers?

1, we first enter the telephone dialing software, and then click the ellipsis at the lower left of the dialing interface. 2. In the function options of the pop-up page, click to enter harassment interception. 3. Next, turn on the options of harassment interception and automatic update of interception library. 4. We first enter SMS interception, and set the interception mode to intelligent interception, which can intercept most spam messages.

Mobile phones always receive a large number of harassing short messages for no reason, some of which are operator bills or bank notification information, and the other part is annoying spam messages. Seeing the worthless information piling up like a mountain, my mood will also become restless. No matter whether it is blocked or blacked out, those short messages seem to grow in my mobile phone. Wildfire has never completely swallowed them, and they are tall again in the spring breeze.
