Ann has an iPhone running iOS 13.3 and she can't see what her battery level is for her Beats headphones anymore. Leo says that the headphone profile is corrupted, and he recommends starting over. Remove the Bluetooth connection by unpairing it in the settings, and then re-pair. That should solve the issue.
Rick has up to six copies of photos on his computer. How can he get rid of duplicates? Leo uses a "dedupe" program called Gemini 2, and it works on macOS and iOS. It's from MacPaw. It'll go through all your photos and figure out which image is a duplicate, which is an edited copy, and more. And for $20, it's worth it.
Rick also wants to know if he can turn an old laptop into a Chrome book. Leo says not strictly, but there is a company called NEVERWARE that has an app called CloudReady, which promises to turn your old laptop into a Chromebook.
Alex wants to do Facebook live by connecting a GoPro to his iPad. Leo recommends considering buying the MEVO camera. It is designed to stream live directly to Facebook, YouTube, etc. in 4K. If he streams in 1080p, it's like having 4 cameras at once. If going with the GoPro, then he'll need to use GoPro's software to do it. The challenge will be inputting the audio. The chatroom says he can use a USB-C mic adapter into the GoPro. GoPro has a 3.5mm adapter here.
Dean is a pianist and teacher and he wants a large tablet that he can use for his sheet music. His friend has an iPad Pro, and he wonders if there's a PC version like the Onyx Book Pro. Leo says that the real key to using a tablet is that if it has the apps necessary to use digital sheet music. Leo says that the basic iPad is very good for this purpose and is very popular with musicians. Samsung has the Note Tablet as well. That runs Android. But for Leo's money, the iPad Pro is the ideal solution. It also has the Apple Pencil which allows you to annotate it. A good app is FORSTER
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 188.8.131.52 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.
