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.
Marty uses WhatsApp with his family, but when he gets a call from someone, it has been displaying the wrong contact. Leo says that WhatsApp looks to the phone's contacts in order to identify who's in it. Marty's personal number may have gotten added to another contact, and all he needs to do is delete his number from that specific contact and it should be fine. Leo says it's probably just a messed up database.
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. Since you recover chats from iCloud, Leo has a hunch it's not cross platform. Apple is very strict on how users can access data within the iPhone platform, but it's usually app centric.
Since Gordon backed them up, he can at least access them from Google Drive.
Many publications including The Guardian reported that the messaging app WhatsApp was insecure and hackable. The creator of that encryption protocol, Moxie Marlinspike from Open Whisper Systems, posted on his blog that this was incorrect. Now a large number of security professionals have written an open letter to The Guardian asking them to retract the story. There is no back door in WhatsApp, and the article was wrong. It was written in a sensational way to drive traffic.
Ben decided to make the switch from Android to iPhone and he thinks he's made a mistake. He did it because everyone else in the family is on the iPhone, but he doesn't get to iMessage with groups. Leo says he can't because Apple's Messages isn't cross platform. Apple doesn't care -- they want to lock users into the iPhone ecosystem.
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.
Corral is thinking of switching back to the iPhone after leaving it for Android after the iPhone 3G. He's concerned about sending text messages. Leo says that Apple always uses Messages for SMS. This is a problem for group messaging. But within the Apple ecosystem, it's best. Other options include WhatsApp and Facebook Messenger, and those are platform agnostic. The downside is, everyone has to use them.
Peter has the Samsung Galaxy Note 5 but he wants to still use his iPhone as well. But because his phone number is registered with iMessages, he can't get the text messages from his Apple friends when he's using his Android phone. Leo says that it annoys him that iMessage isn't cross platform. Peter can go to this site that Apple has set up, input his number, and Apple will turn off iMessage to that number. That way, all the messages he gets will be through SMS.
Using the Paris attack to justify stepping up the intrusiveness of state surveillance, UK Prime Minister David Cameron is calling for and end to any communication that the government is unable to read with a simple warrant signed by the home secretary. Leo says that this can't happen. The US even tried to prevent strong encryption by classifying it as munitions, and it just didn't work because it's really easy to create strong encryption.
