iPhone, Android, Windows Phone 7, Blackberry, or feature phones.
Clyde and his wife both have iPhone 5Cs on AT&T, but they get each other's text messages, and their daughter gets them too. Leo says they share text messages because they all are using the same Apple ID. They'll need to create a separate account for each of them. They won't lose their ability to share apps either, because Apple has Family Sharing.
Clyde is also getting a Blue Screen of Death with a DPC error. Leo says that's usually referring to a problem with the SSD Device driver. It's also due to an old operating system, so upgrading to Windows 10 should fix it.
Sheryl wants to replace her old Razr Maxx Android smartphone. What should she get? Leo says that if she's happy with Motorola, then she can stick with it. Leo recommends the Moto G4. It's between $150 and $200 and Leo says it's a fantastic upgrade. It's well made, and has a good camera. She should just get as much storage as she can.
Scott has a Samsung Galaxy S6 and he's deleted some text messages on Verizon and then tried to recover them, but they haven't showed up yet. Leo says that Verizon keeps copies of his text messages, so if anyone has them, they do.
Karen has a Samsung Galaxy Note 3 and she broke the screen. She bought an unlocked Note 4 from eBay to replace it, but it came in Korean. Leo says that's not unusual. Samsung is global and it sounds like she got one for the Korean market instead. That's why it's always best to buy the phone from the carrier. She'll get a better deal on eBay, but it may not come unlocked. Amazon is another good option.
David is an iPhone user and he wants to start using Google Voice, but he doesn't know if it's better than trying Allo or the other messenger programs. Leo says that iPhone users should just stick with iMessage. All SMS messages will go to iMessage anyway, because Apple doesn't let users change the default messenger app. iMessages will be color coded blue, while regular SMS messages will be color coded green.
Tim wants to know why he's not getting his phone updated. Leo says that since Tim is a subscriber of Straight Talk, it's likely that they aren't sending out all the official updates. Leo advises talking to Straight Talk about when he can expect the next update for his phone.
The only other option is to root it and install it himself, but that's not for everyone. He can find out how to do it at XDA Developer Forums. He'll have to follow the directions to the letter or he'll end up bricking his phone.
Ernesto finally got an iPhone 7, but he can't use iTunes with it because his Mac is too old. Leo says that if he wants to sync it via wire, then he'll have to update his computer. He could pay the $25 for iTunes Match, and that would put his entire music collection up in the cloud. Then he could access the music from his current Mac as well.
Chip's Samsung Galaxy mobile phone had a bunch of pictures on it, but they started disappearing. Leo says that there may be an app that is moving the photos to a folder, and they aren't really missing. Or the images are being uploaded and then deleted to preserve space. For instance, Google Photos does this. In fact, Leo recommends using Google Photos anyway, since Chip will be assured that his photos are being backed up to the cloud.
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.
