Android users have a few different ways to block text messages on their LG phone. The first way is to go to the Messages app and tap on the three lines in the top left corner. From here, you can select “Block Texts.” The second way is to go to Settings and then Security. Here, you can select “Text Message Blocking” and then add any number of contacts who you want to block from sending you text messages. The final way is to use LG’s Smart Security feature. This allows you to set up a password so that only approved people can send you text messages. ..
