Richard turns off Wi-Fi when he's recording from his Android phone with TuneIn Pro. Now he can't turn the Wi-Fi back on. It does work in safe mode, though. Leo says that means an app is causing the problem. Could be a bad update. He should try resetting his phone. He should make sure his photos are backed up to Google Photos, and that he has his Google contacts backed up. Then go into pure recovery mode and wipe everything. He can also back them up to his computer via MTP. Once that's done, the issue should be fixed.
Barry is locked out of his Samsung Galaxy Note 4, and doesn't have a backup. What can he do? Leo says that if Barry had enabled the Android Device Manager, he can change his device's password remotely, along with a host of other security features. That's really his Hail Mary. If that doesn't work, then a factory reset may be his only option.
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.
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.
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.
