iPad, Android, Kindle, or Windows tablets.
Paul uses the iPad Pro for presentations and wants to have a remote to control his Powerpoint presentation. Leo says that if he has an iPhone or Apple Watch, he can use it to sync to the iPad remotely.
Another option is a Bluetooth clicker that supports Powerpoint. He could also just make the move to Keynote. Doctor Mom uses a Satechi Bluetooth Smart Pointer Mobile Presenter and Remote Control.
Jonathan knows someone who lost an iPad in the snow and found it months later. It actually turned on! Leo says Jonathan is incredibly lucky. Leo says to make sure it's fully dried out before turning it on again. He should stick it in a bowl of rice and let it sit for a week. This will draw out all the moisture. There may also be corrosion.
Noah wants to know if Apple will go to USB Type-C connectors on the iPhone or iPad. Leo says no. They just moved to Lightning connectors on the iPhone or iPad. They did put USB Type-C on its MacBooks, but don't look for Type-C on iOS any time soon.
Paul has updated to Android Kit Kat 4.4.2 on his tablet, but now he can't see any files that he's downloaded. Leo says it's likely that Paul is just looking in the wrong place and that he's actually downloaded his files and just can't see them. There are a few download files in Android, one for apps and one on your SD card. That's why Android has gotten rid of the SD card option. It's confusing. A third party file manager like Astro File Manager or ES File Manager will show you what you're looking for.
Cricket has an old iPad and wants to know if she needs to upgrade to a new one or if she can upgrade to iOS 8. Leo says that everything from the iPad 2 and newer can run iOS 8 and it should run fine. Should she buy a new one though? Leo says not really. Apple is having issues selling iPads now because people just don't feel it necessary to buy a new one once they buy one. Sure, she can get a new one if she wants, but she doesn't need to. She should just go into settings and tap on Software Update.
Mike is trying to edit a video with his tablet and it says his file is too large, even though he only needs a small portion. Leo suggests restarting the tablet and make the editor the first thing he runs. If that doesn't work, it is probably a limitation of the app itself.
John is experiencing a brief flash of vertical lines against a white background on his Android tablet. He's swapped out the tablets more than once and wonders if this is a hardware issue or software issue. Leo says that since John is putting the same apps on the tablets, no matter which model he tries, that points to an app or software issue. Leo suspects that the tablet is making a quick adjustment in the video mode as it does in the app. It could be normal since it goes from tablet to tablet. The common denominator is the user, so that's where he can focus his troubleshooting efforts.
Leo says that the Google tablets would be updated first, but frankly, it seems that Google's Nexus 7 and 9 have been somewhat abandoned with no updates in the last few years. He's concerned, though, that he won't be able to use LTE on AT&T. Leo says he'll want to make sure it shares the same band as AT&T supports. The Google Nexus 9 does support every frequency but 700mhz. Leo says that was a recent development and it's what he'll want.
Shelia has a Kindle Fire tablet, but it doesn't hold a charge. Given the age of her tablet, Leo says that the battery is just worn out. Lithium ion batteries have a limited charging life, about 500 cycles. Once she's gone past that, she'll begin to see battery failure. She could try to contact Amazon and see if they can replace the battery. But she shouldn't spend a lot, as a new Kindle Fire is only $60.
Jeff wants to know more about Sony Digital Paper. Leo says it uses e-ink, and while it has extremely long battery life, it has traditionally had a problem with latency. Sony has a video that shows it keeping up with handwriting, so maybe they've overcome the latency issues. At $800, though, it's a bit pricey. But if it does what Jeff needs, being a digital yellow pad, then perhaps it'll be worth it.
