Gary is about to get an Android phone and is concerned about security. Leo says that mobile phones have enhanced security with apps sandboxed from one another, and as such, are extremely secure. Android also has a mobile kill switch for apps, so if a bad app is installed, Google can kill it. So he doesn't really need an antivirus app for his smartphone. He should just make sure to only install apps from reputable sources.
How about recording calls? Leo says that Google Voice can do that. But there's also an app called ACR that will do it. But in many states, he'll have to have consent to record. So he should be aware of what the law is where he lives.
