If you have an iPhone battery swelling up and expanding, it's best to take the cell phone to your nearest Apple Store to get the battery replaced. The store may replace the battery for free since a bad battery can become a hazard (causing a phone to catch on fire or explode). Alternatively, an authorized Apple repair store could help fix the issue. For more on phone battery risk & safety information, check out Leo's recent episode of Ask the Tech Guy at https://youtu.be/LRfvgTFE9zk
David wants to know how he can project his mobile device to a portrait sized monitor. He wants the monitor to have the same aspect ratio as the phone. Leo says that they tried to do that at TWiT, and you can, but it's quite expensive. One solution is to buy the Apple XDR monitor for $5K and the $1,000 stand. But there are other options out there. David has a monitor that will flip to portrait. Leo says that most operating systems can tell when the aspect ratio changes and adjusts. Apple has an emulator mode, where you can run an app on a Mac and it will look like it's on a phone.
Louis travels with his iPad and would like to know if there's a VPN for iOS. Leo says you have a few ways to go. Leo says that 22.214.171.124 is an app that isn't strictly a VPN, but it changes the DNS to give privacy from an ISP. The benefit is that it doesn't slow users down. But if customers want something to completely protect them at a public space, Leo says to purchase ones like ExpressVPN, or NordVPN. Both are offshore and don't log user activity. There's also Tiny Hardware Firewall as another option.
Robert is wondering if he needs to get an Antivirus for his smartphone. Leo says it would be unnecessary since the phones' Operating Systems are already quite secure thanks to Apple and Google's efforts. An Android device, for example, will scan apps downloaded from the Play Store (which is the best a 3rd-party app can do anyway).
Kevin would like to select and delete multiple emails in Apple Mail on the iPhone. Just tap "edit" and then mark it, move it, or trash it. Leo says that one of the problems with the modern iPhone is that there's no standard user interface like the old Macs. That makes it difficult to do things like this when the UI changes.
Bruce wants to know why he's being asked for his iCloud password all the time on his iPhone 8. Leo isn't sure why this happens, but it's happened to him as well. It does go away eventually. Leo thinks it's just a bug. Leo suggests going into settings, and re-entering his passwords there.
Mark would like to sync his iPhone with a Microsoft Access database. Leo says there are several third party clients like Access Frog, Access Database Manager, ACCDB, and Pocket Access. He can also navigate to his Access database through his Safari browser. He'll need to configure his database so it can be read online, however, and that could be a security issue.
Leo says that with its 8 core A12x Bionic Processor and 7 core GPU, the iPad Pro is indeed the computer of the future. It's more powerful than 92% of all laptops sold this year. But iOS is simply too underwhelming to take advantage of all that power. Things you should be able to do, like add an external hard drive or keyboard, you still can't. Sure, some creatives will be able to harness the power, but for most, you'll end up paying a ton of money for what amounts to an overpriced Netflix machine.
Dale is worried that his older iPad isn't safe to use anymore since he's stuck at iOS 11. Leo says not to worry. The iPad is secure no matter the age. It's sandboxed and as long as Apple continues security updates, which it will, it's more secure than a desktop.
