How to set SMS not to update automatically?

We can reject spam by setting "SMS blocking". The specific method is as follows:

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 "harassment interception" and "automatic update of interception library" options.

4. Enter "SMS Interception" first, and set the interception mode to intelligent interception, which can intercept most spam messages.

5. If you still need to set "Telephone Interception", you can enter "Telephone Interception" again according to your own needs and open the corresponding interception options.
