Don has a Windows Phone 7, he's noticing that the security updates are about to run out, and he's concerned about security. Leo says that it's not really cause for concern. He's not using the latest or greatest, but it's such a small market share, that malicious software simply isn't attacking it. Don would like to switch to the iPhone. Leo says he can. It's a good next stop in the smartphone game, and it's very secure. It's not perfect, but at the crossroads of security and convenience, Apple does a great job. In general, smartphones are very secure anyway.
David needs an app that will track his Android phone in case he loses or misplaces it. There's an app on the Google Play store called "Android Device Manager" that will do this. It also comes with a kill switch to wipe out his device should it get stolen. He can ring the phone to locate it, or remotely wipe it.
Eddie wants to know if he should buy an LG G3 or wait for something better. Leo says he hasn't used it yet, but it has the highest resolution 5.5" 4K screen on the market. That's ultra high definition. But Leo doesn't think he would be able to see a difference. It will impact battery life, too. But he can always get extra batteries to get him through the day.
LG makes top of the line smart phones, but they have a wacky button design on the back. The camera is decent, but not great. It's a little slow. It does have laser focusing though, which is interesting.
Barry gets lousy cell phone reception at work. Leo says there are signal repeaters such as the Wilson Electronics Cell Phone Signal Boost. Barry would place the antenna in a place where there is signal, and it would send the signal to the booster which would repeat it.
Kim wants to switch carriers and wants to know the best option for getting an iPhone. Leo was going to suggest T-Mobile, but that's where Kim is and she doesn't want to have a contract. Leo says that without a contract, she'll have to pay for a phone unsubsidized. She can also buy the iPhone 5S unsubsidized and make payments on it, but that's just like having a contract. Should she wait? Leo says we'll know when the iPhone 6 is coming out in a couple months. It'll probably be out in September.
Jeff's old Android phone is dying really quickly. Leo says it's likely because it's nearing the end of it's rechargeable life. Phone batteries have a limited number of charge cycles, at about 500. After which, it will die pretty quickly and won't take a charge anymore. That's why it's best to leave the phone plugged in all the time unless he's out. It will preserve that limited amount of charge cycles, and it's perfectly safe to do so. If it's not holding a charge, it's worn out and the battery needs to be replaced.
Sandy's Samsung Galaxy S3 isn't holding a charge anymore. Can she just replace the battery or does she have to buy a new phone? Leo says she can definitely just replace the battery. All she needs to do is open up the back of the phone and pull out the battery. She can buy a new battery to replace it.
Tom is about to go traveling and would like to clean off his videos and photos. He uploaded the videos to YouTube, but when he deleted the videos off his phone, they were deleted on his YouTube Channel as well. Leo says that's odd. YouTube isn't caching his video on the phone, but it may be that YouTube syncs to his iPhone through iOS and any changes he makes there affects his channel on YouTube.
Diego wants to know if he should wait to buy iPhone 6 when it comes out or make the move to the Samsung Galaxy S5. Leo says that we don't know what's going to be in iPhone 6 and the earliest we'll know is the Fall. We have a hint at what it will be able to do with the preview of iOS 8, though.
Scott says he wants to see the Northern Lights and photograph it. Chris says that it's very difficult to take pictures of the Northern Lights because you need long exposure and it can be tricky. But if you do it right, you get very interesting shapes and colors. Chris also wants to talk about Apple killing Aperture Software Development. Chris says that these days, Photographers like to use MetaData and Aperture was really good in helping to organize photos by that MetaData. Now that it's gone, the only real professional option is Adobe Lightroom.
