Why does my phone butt dial?

Episode 1438 (1:31:22)

Dave from Ridgecrest, CA
Feature Phone

Dave has a problem with a Tracfone that "butt dials" 911. What can he do? Leo says that there's a feature in Tracfone that has physical buttons and a lock that prevents them from being depressed when he has it in his pocket. Modern phones solve this problem with lock screens, but Leo says it doesn't always work either because people don't wait until the screen locks before putting the phone in their pocket. It could be that his phone lock is broken.
