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.
Jack bought the HDMI adapter for his iPhone to watch video on the TV and it doesn't work! What can he do? Leo says that he gets this complaint a lot and there may be an update in iOS that broke the connection. It could be copy protection. But you'd think that if Apple sells the item, they wouldn't break it with an update. Apple says to be sure the TV is set to the right HDMI selection. It should work automatically.
Fred has an iPhone 6 that's been updated to iOS 11. But when he updated it, he lost his password vault file. Leo says that Apple discontinued support for 32-bit apps in iOS11 and as such, a lot of apps simply broke and stopped working. They won't work unless the developer updates them. Fred will have to contact the app developer and see if they're working on a solution. If it backed up the data to DropBox then he may see it there.
Byron has the iPhone 7 and the iPhone 6S Plus. He wants to know if he'll have issues upgrading his 6S Plus to iOS 11. Leo says that there's been complaints about loss of battery life updating to iOS 11. Even Leo's wife has noticed that on her 6S Plus. Leo says that they've also put out a few patches to fix issues that crop up. He always recommends waiting at least until the third patch after a new operating system comes out. Since iOS 11.1 is the current, it's OK to go ahead and update.
Dana has an iPhone 7 that's been updated to iOS 11, but the phone will not sync and display his contacts, so he can't use his car to make a call. Both Honda and Apple are blaming each other. Leo says this is a common problem with Apple/Honda owners. Nobody seems to have solved it, they're just complaining about it. One would hope that Apple would fix it in a future update. Honda isn't going to update their firmware.
Joshua has a love-hate relationship with his new iPhone. It's freezing up a lot. iOS11 also has a glitchy screen, too. Leo suspects that it's a Lemon and since it's within about 3 weeks, he should be able to get a new one. Leo says there's some good features in it and if he brings it back to the store, they should be able to swap it out. It's definitely a lemon. That's all behavior that isn't normal. Battery life isn't as good as the iPhone 7, but not as bad as Joshua is complaining about.
George has an iPhone 7 and he keeps getting asked to update iOS 11. His wife doesn't want to upgrade due to battery life issues. Leo says that he has iOS 11 and it runs just fine. A certain percentage may run into problems, even 1/10th of 1% would still be thousands. That's just the nature of the business. George doesn't know how to stop the notifications of iOS 11 other than to just ignore it. Once he upgrades, he can't go back. That's why the conventional wisdom is to wait a few weeks on updates, because there will be patches coming out in short order.
Barbara has an iPhone 5S that keeps bugging her to install iOS 11. Should she? Leo says if Apple thinks it can run it, then she can run it. Security improvements are a good benefit. Also, some apps may not run without it. But the reviews say it will slow it down. It will still be faster than an iPhone 5 running iOS 10, though. So she should go ahead. It'll be usable.
