Charles wants to know why Linux doesn't have a touch screen interface. Leo says it does -- it's called Android. Linux itself is a kernel with additional features on top of it. Android has become the touch version of Linux.
Sam is thinking of rooting his phone so he can buy apps from other places. Leo says that he could get Android apps from almost anywhere with a simple check box in settings. Rooting gives the owner super user or admin access to backup the phone, and erase apps and overlays they want the user to have, etc. Should he follow the tutorials he finds on YouTube? Leo says he wouldn't. There's a different procedure for every single phone. He won't want to follow the wrong suggestions and brick his phone.
Jonathan is looking to make "the Switch," from the iPhone to Android. He has an iPhone 5S and he isn't happy with AT&T. Leo says that the iPhone 5S is unlocked and as such, Jonathan could bolt and take that phone to T-Mobile. T-Mobile may even pay him to do it.
Jen has an old Samsung Galaxy mobile phone that was bricked during an over-the-air update. She's also heard that others are having the same problems. What can she do? Samsung doesn't seem to care. Leo says it could just be a bad battery, which she could replace. If that isn't the problem, then the update is the culprit. If she can get into recovery mode, then there's a chance. To do this, she should press the On button and volume up button at the same time and hold it until it gets into recovery mode.
Lee has a Blue Life View mobile phone. The phone has dual sims, which is primarily used overseas when crossing international borders.
Leo doesn't like that it uses Android 4.2, which is a bit dated. Also, since it's an international phone, he'll want to check that the frequencies from his carrier are supported. It won't support LTE, which means he won't get the fastest data. But it's not bad for the money. Leo recommends getting the Motorola Moto G, which has the same specs for half the price. It isn't dual sim, but unless he's traveling overseas, it's more than enough.
Frannie learned to build computers from Leo and Patrick several years ago. But now, she's a bit lost with all this mobile phone stuff. She picked up a Samsung Galaxy 4, while her husband got an iPhone 5S. He hates the 5S and she loves the Galaxy 4. Leo says that aside from the junkware, it's a nice phone. But what she wants to know is, how does she back it up? Leo says that there's a default setting that lets Google backup apps and settings. When she signs into Google, it starts backing up automatically.
John just stopped using his iPhone in favor of the Samsung Galaxy Note 2. He wants to know if he can jailbreak his iPhone to be used as an iPod. Leo says sure. What about rooting the Note 2? Leo says he'll have to be careful rooting his Android phone. It's very specific to the model. John should check out his specific model at XDA-Developers.com. He can enter his device under "Find Device on Forum" and it'll take him to all the posts for that particular model. The root posts are "stickied."
David got a Motorola Moto X and wants to be sure that when he's home, he's using Wi-Fi and not his cellular data. Leo says that if the Wi-Fi "volcano" icon is displayed, he'll always be using Wi-Fi instead of cellular data. The phone is designed to always prefer Wi-Fi. But sometimes he may end up using Cellular. It's so infrequent, that it won't affect him.
The Moto X has great voice features, called Motorola Assist, to read and send text messages hands free, and will automatically tell callers when he's driving. It's a great feature. It's a perfect first smartphone.
Mark is dyslexic and he's noticed he can read better with smaller screens. Leo says there's a great app for the iPhone and iPad called ReadQuick. It's designed to teach people how to speed read, but it's also good for dyslexic users. It will enable him to read without moving his eyes.
Chris is a bit jealous because his girlfriend's Samsung Galaxy S5 is so much larger than his iPhone 4s. Leo says that is true, but Samsung also has a lot of bloatware on it. In june, Apple's Worldwide Development Conference may give us some hints about the new iPhone, iOS 8, etc. We may find out whether or not the next iPhone will be larger. So if he can be patient until then, it may pay off.
