Max has read that the iPhone 7 emits twice as much radiation than any other phone and he's concerned his wife is being exposed. Leo says that radiation coming off a phone is "non-ionizing," which means it poses no harm to people. There is no evidence that cellphone use contributes to brain cancer. In fact, brain cancer statistics have gone down over the same time as smartphone use has gone up.
Bob wants to know if it's safe to upgrade to iOS 11. Leo says it is, and not only that, but iOS 12 will be released next week along with macOS Mojave. Leo adds that iOS 11 was a really bad update, and even though there's been several fixes and updates to improve it, there's still a lot of shortcomings with it.
Researchers have figured out that if you connect your iPhone to a computer, you can keep doing a brute force password attack to unlock it and that it should take about a day to open it. Leo says that this is with a four digit passcode, and a six digit passcode is a lot harder to crack.
The Supreme Court has also ruled that law enforcement cannot get cell phone location data without a warrant. The decision said that day to day movement data on a mobile device provides an intimate look at someone's activities, even to the point of violating privacy without a warrant.
Kim dropped her iPhone and broke the screen. Apple said she has to buy a new phone because it's bent and the display won't seat. She hears that it's a common problem. Does she have any recourse? Leo says not really. Metal phones can be bent and Apple has not acknowledged any potential flaw. This is why buying Apple Care is a good investment. They will treat her better if she's bought it. Leo says that Apple gives a lot of leeway to Geniuses to replace phones, but she'll catch more flies with sugar then vinegar. But these devices are fragile and they can break.
Diane updated her iPhone 5S to iOS 8 and now it's not running properly. She clicks on one app and another one opens. Leo says that there's always the potential of something going wrong when updating an operating system. It's like trying to pull a table cloth out from under dishes and trying to put another table cloth in its place.
