Is WhatsApp secure?

WhatsApp

Episode 1516

Patrick from Palo Alto, CA

Patrick uses WhatsApp, but he's concerned about security on his phone. Leo says that the danger isn't that the app will be malicious. It's a safe app if he gets it from the Google Play or iOS App stores. But it is owned by Facebook, and they will use his data for advertising. It isn't using personal details, but some details such as search data, likes, and keywords.

Patrick is also worried that his old iPad isn't being updated anymore. Leo says that while he won't get the most recent iOS, the security updates will continue. Nothing to worry about there.

Gordon from Los Angeles, CA

Gordon has made the switch to the iPhone and wants to know how to get his old WhatsApp messages back on his iPhone. Leo says that it was smart that Gordon backed it up to Google Drive, but WhatsApp says it depends on the phone being used.

Why can't I get replies from group text messages?

Episode 1248

Bruce from Riverside, CA

Bruce is having trouble getting responses with group texting through Verizon. Leo says that happens to his wife as well. Often they arrive a day later, sometimes not at all. Leo says it may be a handshake issue between carriers. It also could be that some people in the group text may be using iMessages with an iPhone. Most users don't realize that when they use iMessage, they're using data and not the SMS system. As such, some just don't get the message because they're on two different networks. The best solution is to go with a data only system like WhatsApp or Facebook Messenger.
