iPhone, Android, Windows Phone, Blackberry, or feature phones.
Joe is selling his mobile phone to a friend. How much should he sell it for? Rich says to check under eBay and see how much his model phone has sold for under "completed items." Then look on Gazelle and get a quote there. The right price is somewhere in the middle.
On Thursday, FEMA will conduct a test of IPAWS: Integrated Public Alert and Warning System. It will send a message to all the phones in the US to test the infrastructure of the warning system. The test will happen around 2:18 PM ET and will last a half hour.
Rich says it's a big deal that the federal government will take command of every cell phone tower in the country in order to reach everyone at once with a test emergency text message. Rich also says that while there is an opt out provision for some emergency alerts, this isn't one of them. You cannot disable it.
Maryanne's iPhone 6 won't recharge and now it's dead. What can she do? Rich says that her iPhone battery could be depleted or faulty. The battery in the iPhone has a limited number of charges, and once it surpasses that, the battery will die. And being an iPhone 6, it could be that the battery needs replacing. But before doing that, she should try using a gentle burst of canned air into the lightning port. If it starts to charge, then she'll know there was just a little dirt or fluff blocking the connection. If it doesn't work, then it's time for a trip to the Apple Store.
Scott got an Anker backup battery and sometimes he gets a warning that the accessory may not be supported, and it stops charging the phone. It even does it with the Apple charging block. Rich says that Apple has a program called Apple MFI (made for iPhone). If his accessory is MFI, then the culprit could be a failing cable. It could also be that his phone's connector could have some lint in it preventing his cable from connecting completely. Rich suggests taking a toothpick and sweeping it out. A gentle burst of canned air is a good idea too, but he should be sure to be gentle.
This week Apple announced the iPhone Xs, Xs Max, and Xr. Rich says it sounds like a drink you buy at the gas station. Why Apple dropped the "Plus" moniker is beyond Rich, because Plus and Max are really the same thing, except the new iPhone Xs Max has an edge to edge screen, rather than any sort of bezel.
Dave is a YouTuber, and when he streams live, it works better using LTE and his smartphone than his webcam and desktop using Wi-Fi. Leo says that in theory, they should be the same. Leo says that his Logitech C930 webcam could be misconfigured. Or, he could consider better lighting. Better lighting is always an improvement and helps the camera to pick exposure, color saturation, etc. At the end of the day, though, his LG smartphone probably just has a better camera.
David wants to know if he's secure surfing the internet on his mobile device. Leo says that nothing is unhackable, but LTE is encrypted and very secure. A phone can be hacked, even at the radio level, though. It's also possible for someone to spoof his SIM card. But it's too much work for the average hacker. It would have to be a state level attack in order to accomplish it. Wi-Fi is less secure, and if he's relying on WPA2 or any other Wi-Fi connection, it's possible to hack it. But that's not easy, either. Odds are, there's really not all that much to worry about.
Bob wants to know if it's safe to upgrade to iOS 11. Leo says it is, and not only that, but iOS 12 will be released next week along with macOS Mojave. Leo adds that iOS 11 was a really bad update, and even though there's been several fixes and updates to improve it, there's still a lot of shortcomings with it.
