George uses his iPad to call Uber, but they don't know where to pick him up. Leo says that's because the iPad doesn't have GPS. The app just has to ask for the address of where he is in order to find him. With a mobile phone, they would have his coordinates in the app. Without GPS, the app has to use other means to find his general location, usually it uses "WiFi triangulation," and that's not always very accurate. The app puts a pin where he is, and if it's using WiFi triangulation, the pin just goes close to where he is. The good news is he can move the pin in the app.
Brian wants to know if he should get a mobile phone or a dedicated GPS. Leo says that the benefit of using a smartphone is that he'll get a map with his GPS bearing. He can also cache the maps locally onto the phone and not use data when he's out of reach of WiFi.
Milian wants to know why he can't use his maps app on his Samsung Galaxy S5. Leo says that Milian may have not given the app permission to use his location and as such, it won't access the GPS. But if it used to work, then there may be a hardware issue, like a flakey antenna. It may have a lose connection. He may want to go to the store and ask them to check it. If it's out of warranty, then it may be time to get a new phone and the timing is perfect since the Samsung Galaxy S8 is coming out this week. That will drop the price of the S7 as well.
Tom is looking for a GPS watch that has cellular service, which can be worn by a sleep walking child. They need to have a lockable wrist band so he can't take it off. Leo suggests several GPS watches out there, but none with a lockable watch band. Leo recently got the Samsung Gear S3 Frontier. It has all the features Tom is looking for, as well as a 22mm removable band that can be replaced. You can also make calls to and from it. The battery life is on long side for a smart watch.. MSRP for $350. It is compatible with Android or iOS.
Mark drives for Uber, but now his Moto G Android phone is having GPS issues after updating. Leo says it could be that his GPS is damaged or he got a bad update. He should try restoring the phone first. But since the Moto G is a few years old, it may be time to get a new one. They're pretty cheap.
Can he go back to the previous Android OS? Leo says he may be able to, but Marshmallow was an important update.
Scott has an iPhone 6 and he uses it to get around while hauling equipment, but lately it hasn't been working well -- ever since the last update. Leo thinks that Scott's iPhone has a damaged GPS receiver. He hasn't heard reports of GPS problems after updating, so he has a hunch it's a physical hardware issue. Scott should bring it into the Apple Store.
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.
Walt is a Ham and wants a Windows Tablet that can handle avionics while he's sailing, and Ham radio software. Leo says that the Surface Pro 3 may be a better option than the Surface Pro 4. It has GPS in the LTE model, while the Surface Pro 4 does not. Asus makes a really nice one as well. Also, the Surface Pro 3 is on sale right now.
Jonathan's phone has been reporting inaccurate location information. It's always connected to the data network. Leo says that the data network often defaults to the data center which can change. Leo says to try a different app to see if it's an app centric issue or a phone issue. He should go to Google Maps. It will tell him where he is at all times and he can see where the GPS is reading in its history. It could be a failing GPS chip, or sometimes the location information being transmitted from the network.
Mark has a Google Nexus 5 and he says it gets terrible battery life. But the worse thing is that he's having issues with sound. So he restarted the phone, and it fixed everything. Leo says that the Nexus 5X will be a bit larger, and there's also the 6P which is even bigger. But after Mark broke his phone and had it fixed, the phone's GPS no longer works. Leo says that the antenna could've been broken at the connection when Mark dropped it. He recommends going to iFixIt.com. If anyone would know how to fix it, they would.
