iPhone, Android, Windows Phone 7, Blackberry, or feature phones.
Frederick uses an open access port with his iPhone but it always asks him to sign in. Leo says that's called a captive portal, which is done when using a hotspot. He needs to activate the portal. He should point his browser to 18.104.22.168. Or he can choose to "forget" the Wi-Fi access point. That will reset it and then he can sign back in. Leo actually recommends getting a travel router like the Tiny Hardware Firewall to protect him.
Marty uses WhatsApp with his family, but when he gets a call from someone, it has been displaying the wrong contact. Leo says that WhatsApp looks to the phone's contacts in order to identify who's in it. Marty's personal number may have gotten added to another contact, and all he needs to do is delete his number from that specific contact and it should be fine. Leo says it's probably just a messed up database.
Joe has an old Vista computer that he uses mostly for syncing an old Windows Phone PDA. Joe would like to take that laptop and put Linux on it with an SSD. Leo says that Linux is a good idea, but that Vista laptop is probably not fast enough to get any great benefit from an SSD. But he should definitely install Linux on it. Leo likes XUbuntu and LUbuntu, which is designed to run on the older hardware.
David tethers his computer through his mobile device, but he's wondering if it's secure. Leo says it's probably more secure because cell phones are encrypted now. Using the Wi-Fi through his phone is a different matter, if he's at a public hotspot. At that point, his traffic is out in the clear and easily grabbed. If he's going to use a hotspot, Leo advises using the Tiny Hardware Firewall and a VPN. The Tiny Hardware Firewall is like a router that then connects to his phone.
Steven discovered that when he listens to satellite radio on his phone and puts it near his radio, he can hear it come through on the radio? Leo says that's crazy and isn't quite sure how that could be happening. Wouldn't it be cool if it were possible to do that regularly?
Jill wants to find an app where she can record herself playing a few different instruments and then play them all together. Leo says there aren't many apps for audio recording and play back on Android because of a massive latency bug. Leo believes it's in the kernel, and they haven't fixed it yet. She can find out more about it at superpowered.com.
Ryan has an Axon 7 Android phone. Leo says it was one of his favorite phones last year with excellent sound quality, great battery life, and half the price of flagship phones. Ryan is ready to upgrade though and he's looking at the HTC U Ultra. Leo hasn't used it yet, and it doesn't come out until mid March. From the looks of it, Leo says it's a sweet phone, but it doesn't have a headphone jack!
Gordon has made the switch to the iPhone and wants to know how to get his old WhatsApp messages back on his iPhone. Leo says that it was smart that Gordon backed it up to Google Drive, but WhatsApp says it depends on the phone being used. Since you recover chats from iCloud, Leo has a hunch it's not cross platform. Apple is very strict on how users can access data within the iPhone platform, but it's usually app centric.
Since Gordon backed them up, he can at least access them from Google Drive.
Deena wants to be able to record the audio when she's talking on her phone. Suggestions? Leo says that eCamm PhoneView is a great solution. But she should remember that she'll have to get permission to record in some states.
Mark finally got a Google Pixel XL, which was on back order. Leo says it's been widely known that they're only available in limited quantities right now. It's likely that the demand exceeded Google's expectation. Mark says he likes the Wi-Fi assistant because it'll automatically connect via VPN. Does it really work? Leo says yes. Phones can be a bit promiscuous with random hotspots. So Google adds an encrypted connection via VPN to protect users. Leo says he doesn't really like joining Wi-Fi access points automatically, so he's turned it off.
