Is surfing the internet on LTE secure?

4G LTE

Episode 1522

David from El Monte, CA

David wants to know if he's secure surfing the internet on his mobile device. Leo says that nothing is unhackable, but LTE is encrypted and very secure. A phone can be hacked, even at the radio level, though. It's also possible for someone to spoof his SIM card. But it's too much work for the average hacker. It would have to be a state level attack in order to accomplish it. Wi-Fi is less secure, and if he's relying on WPA2 or any other Wi-Fi connection, it's possible to hack it. But that's not easy, either. Odds are, there's really not all that much to worry about.

Can I use an external camera with an app on my iPhone?

Be My Eyes app

Episode 1518

Larry from Prescott, AZ

Larry wants to use his camera with Be My Eyes on his iPhone, an app for the vision impaired. Leo says the first thing he'll need is a camera that can connect over Wi-Fi. Then he would need an app to allow him to remotely control it from the iPhone. Leo says that iOS sandboxes each app for security purposes, so one app can't compromise others, so he likely won't be able to use a separate camera with that particular app.
