iPhone, Android, Windows Phone 7, Blackberry, or feature phones.
Mike's Galaxy S7 Edge keeps pinging that it's connected to a USB even when it isn't. Leo says that could be a ghost issue. He should turn off USB debugging in the developer settings. He needs to go to into Settings > About Phone, and tap the build number 10 times. Then he'll get into the developer's menu. He should check his phone's USB port for fuzz. He can also try resetting the phone. Then before he reinstalls his apps, he should make sure it isn't happening. If it does still happen, then he does have a hardware problem. If it doesn't, then an app is likely the culprit.
Glen is thinking about getting a Google Pixel. How's the signal quality? Leo says that as far as he can tell, it gets great signal reception. But he says that's more due to the carriers, which also add Wi-Fi to calling. So the problems are being solved for coverage. They also use the same radio devices. There's no reason not to get the Pixel, except the price. It's expensive.
Paul wants to buy a hotspot. Leo says that the Karma Go is one he uses. He can pay as he goes, or pay monthly if it is to be his primary subscription. It uses Sprint, so he should check the coverage map. T-Mobile, Verizon and AT&T offer similar devices for around $10 a GB. No rollovers.
Ben decided to make the switch from Android to iPhone and he thinks he's made a mistake. He did it because everyone else in the family is on the iPhone, but he doesn't get to iMessage with groups. Leo says he can't because Apple's Messages isn't cross platform. Apple doesn't care -- they want to lock users into the iPhone ecosystem.
Aaron has to carry around two phones and wants to know if Google Voice will allow him to use two numbers for a single phone. Leo says he can, but there are also some phones that will allow him to use two SIMs. Google Fi is a good option. He can also use phone services like RingCentral and Grasshopper. Those are pay services, though. Skype could be a good alternative. Leo just keeps using Google Voice. It gives him a lot of options.
Chris has an iPhone 6 and with iOS 10.1, and he's getting strange colors when he resets it. Leo says that is a symptom of "touch disease," which is from a faulty video chip used. It misbehaves and starts spewing random data that can eventually get worse. Apple hasn't acknowledged it yet, although thousands are complaining about it. Even Apple Store techs are saying it's a common feature they are finding that requires repair, and Apple is charging to repair it if the phone is out of warranty.
Shar wants a new iPhone but what about her headphones? Leo says that the new headphones will have a lightning connection to plug into the phone, and there will be an adapter for older headphones. Unfortunately, it's not possible to listen and charge at the same time without an additional adapter. Not having a headphone jack is less of a big deal than Shar may think, though. Of course, the way around this is to use Bluetooth headphones.
Greg wants to know if he uses a magnet to connect his phone to his dashboard, will it affect his GPS? Leo says no, it won't. In fact, many cases, like Rokform's, can use a magnet to enable you to do just that and Leo has not seen any issues. It could screw up the compass, if he's relying on that, but it shouldn't affect his GPS.
Rod is looking for a smartphone that has a special feature. His old flip phone had an 'auto answer' feature where he wouldn't ever have to touch the phone. Leo says that any Android phone has that feature, but it's buried deep in the settings. It's buried so deep that many stores don't know about it. iPhone even has this ability in Settings > Accessibility. So he should start with that. Some have a feature that will answer when the phone is raised up.
Gordon is having issues with his new Samsung Galaxy S7 Edge showing funny lines on the screen. He returned it, got another, and this one is also developing the lines. Leo advises resetting the phone and not putting anything on it. Let it run for awhile. If the lines don't appear, then it could be an app issue. But if it does, then he'll know it's a hardware issue. He's hearing this issue is affecting more phones.
