The Old Geek is worried about bad flashlight apps which could be malware. Leo says there's nothing to worry about. Both the Android and iOS app stores scan all apps and disable those that have malware. And even better, today's modern OS offers that flashlight capability natively.
John uses Windows, but he has an iPhone 6. The one thing he doesn't get is why Apple computers don't have a delete key. Leo says that Apple wants to get rid of older keys from the early days of computing, including Print Screen, Pause/Break, and even the Delete key. Apple actually got rid of the Delete key a long time ago. John will have to press CMD/Backspace to duplicate that function.
David has a first generation iPad Mini and it won't clear out an old Apple ID, even after doing a reset. Leo says that the new version of iOS requires users to verify the old Apple ID and password to prevent theft of a device and then just wiping it. Leo says one thing that David can try is a DFU reset.
Seven has been having issues with his iPhone and the Apple store says there's a bad app causing the problem, and he should wipe it. When he restores from iCloud, however, that app will come back. Leo says that the Apple Genius isn't being much of one this time. Apple vets all the apps, so it's unlikely the app is the culprit.
Chris can't find out how many songs he has in Apple's new Music app. Leo says to try sorting by songs. But it could be that Apple has dropped their obsession with the number of songs available. Leo says to go into the Settings -> General -> Usage settings and he should see how many songs he has. It should be app specific and Apple has been moving stuff like this to settings now.
Dave is debating making the switch to the iPhone so he can be in line with his daughter. Will he have any issues moving from Android to iOS? Leo says that there will be a learning curve and he'll have to reinvest in several apps. But there is more in common between the two than what separates them. Leo does like the Samsung Galaxy S6. Google Now is great, and it is better than Siri. iPhone apps, though, are better designed and the security is far better in iOS. So, in general, it's far more secure and Apple can force updates.
Carlos has made the switch from iOS to Android and wants to be able to select a paragraph of text and then have Android read it. Leo says that iOS has great accessibility features and he doesn't think that Android can do that. But the new iPhones would enable him to select text and then use 3D Touch to bring up a cursor so he could highlight easier. Google's text to voice engine is very good though, but it only reads files. He should check the accessibility settings.
Devin wants to learn how to write apps to create games. Leo says that the skill is in high demand and every kid is taking computer science classes to learn it. Leo advises starting at iTunes U, which is free. For Android, most of it is written in Java. There are a lot of tools to write in both platforms. Google has great resources on how to write for Android at Android.com.
