Kim is worried that her Android phone may get hacked. How can she prevent it? Leo says that Android is more open source and is more vulnerable to attack than an iPhone. But really, the best way to guard against it is to keep your phone up to date with Google's security updates. Can she get hacked by clicking on a link? Leo says it's possible, but the most common way is to download a bad app from the App store. Only download apps that are well known from well-known companies. Avoid any apps from Russia.
Leo says if you don't click on a link, the link can't hurt you. But if you have clicked on a link, a factory reset will solve that problem. Just make sure your data is backed up.
