Question

Do I use the phrase "to do something about something / someone" correctly?
1 Our trees are spoiled. I want to do something about the garden ants. 
2 What are we doing about the crack in the wall?
3 What are you doing about 56 number Connor Randall? He stopped some of our attacks. 
4 I'm going to do something about the crashes of our application.

Answer
