Is there any mobile phone software (Android) that can completely block a batch of text messages and phone calls?

You can do this by blacklisting. The security management software intercepts and shields more thoroughly without any warning.

Take LBE security master as an example to illustrate the operation process:

1, LBE security master for mobile phone installation.

2. If your system doesn't have ROOT permission, it will automatically help you get ROOT.

3. Click the menu in the upper left corner, that is, the key in the three columns, select harassment interception, select click on phone and SMS, and add it to OK.

It also has the functions of prohibiting self-starting, prohibiting software that does not need to connect to the mobile network from automatically connecting to the network, managing software, setting a blacklist and so on.
