Devon 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 glasses to learn. Leo advises to start 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. There's also plenty of online sources like at UDacidty, Lynda, Coursera. Google has even created a "nano degree" that allows you to get certified in about a year, and that will get you a job.
BJ has been using the same mobile phone for eight years and everyone says he needs a new Android phone. Is the Motorola Moto-X a good choice? Leo says the Moto-X is a good phone, and it's about to be updated. But it's got battery life issues. Check out the lesser expensive Moto, the Moto-G. You can get it through Motorola.com for $250 out the door. And you can then just put your sim in an you're off to the races. It's the best Android phone out there for the price. It's got better battery life that will get you through the day easy.
Benny got a $50 Polaroid Android Tablet. Is it secure? Leo says that mobile devices are inheritently more secure because they were developed long after we became aware of security issues. So they are sandboxed to prevent a lot of exploits. They're also very limited in what they can do -- they're more "dumb" than a desktop.
Stephanie has a pair of Samsung Galaxy S3 phones she got from eBay. Leo says that the very first thing she'll want to do is wipe the phone. She should restore it back to its factory configuration. The bottom line is that she doesn't know what's on that phone since it's from a stranger. Also, if it's overheating, that means that there could be spyware on it that's constantly phoning home and overworking the chip. Remember, when buying something used, especially from eBay, you're inheriting someone else's problems. So always do a reset when you get it.
Jonathan wants to know if there's an Android equivalent to DBAN (Derek's Boot and Nuke). He wants to be sure to wipe his older phones and tablets completely. Leo says that the problem is that solid state discs can't really be erased effectively. It's because of the wear leveling software that SSDs use. Leo says one thing he can do is turn on encryption. That way, it's just word salad across the entire drive.
When getting a new phone, it can be a hassle to reinstall all of the apps you were previously using on your old phone. There's a few ways to make this process much quicker and easier, though. First, with Android 5.0, you can transfer your data over Bluetooth and NFC. It's called "Tap & Go," and you can transfer content by simply tapping the old phone to the new one after selecting "Tap & Go."
Zach lost a bunch of videos and wants to know if he can recover them. He's on a Mac. Leo says that the first thing he'll have to do is stop using his phone. The videos are still there until they get overwritten. Leo says the problem with relying on Cloud backup is that if he deletes the original, he no longer has a backup. So if the cloud backup failed, then he's stuck.
G. Scott has finally ordered a Samsung Galaxy Note IV. How can he move his apps from his old Note II to his new Note IV? Leo says that with Android 5.0, he can copy everything over via Bluetooth with a tap. But he'll also want the latest apps, and that will require downloading his apps, which he'll want anyway. Android has a backup to Google option, then he can restore the settings and the list of apps to his new phone.
Paul bought a cheap $60 tablet. Is that a good deal? Leo says that sometimes it's a false economy to go that cheap. If he has a kid, though, it may be smart to have an inexpensive tablet in case it broke or was lost.
Leo says if it's just not on, it probably lost its charge. Paul should plug it in and let it sit for a long time. Then log in and reset the default settings. That should bring it back up and running. But if not, it was only $60 and he isn't out much. Can he take it apart and fix the screen? Leo says maybe.
Ron bought a Samsung Galaxy Note IV from T-Mobile and he's having issues with the hardware. They offered him a refurbished replacement. Leo says that Ron should be able to get a new one under warranty and he should stick to his guns and demand it. That being said, refurbished isn't bad.
