Watch Terry from California Comments

Terry wants to know why the RING doesn't show an image like it's supposed to when he gets notified. Leo says that the RING camera will go to sleep. It's not on all the time, so he may have to wake it up to get an image. Once it wakes up, he will get an image, but by then, it may be too late. He also has to modify the doorbell chime. 

Watch Lex from Richmond, VA Comments

Lex and his wife have identical Samsung international phones. But when they travel to Richmond, VA, his wife's phone stops taking and receiving calls. What gives? Leo says it's because he bought an international phone. Each carrier supports different radios. So he can travel to somewhere in the US and those phones won't be supported. Leo recommends going to GSMArena, enter the model number, and it will tell what radios it supports. But his works while her phone doesn't. Leo says it's possible he doesn't have the exact same model, but very close. It could also be a configuration issue. Look and see if the phone has VOLTE enabled. It's also possible that the carrier turned off those towers, causing the problem. Or it could be a radio issue.

Watch Joey from San Diego, CA Comments

Joey wants to know if Linux has a built-in VPN. Leo says no. He will need a provider to handle VPNs, not just software. Leo recommends visiting the Wiki for ARCH, a version of Linux. There's a great list of clients, carriers and servers that will run on Linux. That's the best place to start. Where can he get apps to download for Linux? Leo says that PopOS has its own "store," called the PopShop, which is an app that will help to install software.

Watch Scott from Orange County, CA Comments

Scott watched the recent Apple event and it got him thinking about multiple lenses/cameras shooting a film simultaneously during production. Leo describes the pain of shooting an interview with only one camera, where the reactions often come across as a bit fake. Scott explains how the movie Focus was screened in front of audiences using four different versions, and the final edit blended them together based on audience feedback. Leo believes more in auteur theory and artistic vision, but the possibility to combine filming styles is still there. 

Watch Steven from San Antonio, TX Comments

Steven logged into the hospital internet on his iPhone, and he lost all his numbers. It reverted back to an old phone backup. Leo says that's an odd thing. Sync is notoriously troublesome because it doesn't usually know what version is the current, official version. Look at all the accounts the phone is logged into and see what account syncs to the contacts. That is usually what happens. Users wind up logging into a different account, and it wipes out the existing contacts.

Watch Carmine from Chicago, Illinois Comments

Carmine has a Chevy Bolt with Apple CarPlay and every time he hits a bump, Carplay disconnects. What gives? Leo says that the only logical conclusion is a loose connection. But he can also check to see if there's lint in the lightning port. A little dust will cause a looser connection of the lightning connector. A little canned air should solve it. Also, try a different cable. Lightning cables can get damaged easily. The other side may be loose as well. Past that, it's a visit to the service department at Chevy. 

Watch Ben from Auburn, AL Comments

Ben has an issue with 2-factor authentication. Leo says that text message 2-factor authentication isn't safe anymore because "sim jacking" can occur, by bad guys figuring out what your cellphone number is, and then using social engineering to get them to reassign that number to a new SIM. Once they do that, they have control of the mobile device and can control even 2-factor authentication. That's why Leo supports using an authenticator. He uses a hardware-based model called Authy. Also, users can get their account back by giving Google a separate number and non-Gmail email address. That's why Leo recommends 2-Factor Authentication but encourages turning off text messaging fallbacks.

Ben can also set a PIN number on his mobile account. If bad guys don't have that, they can't sim jack.
