iPhone, Android, Windows Phone, Blackberry, or feature phones.
Here's a clever device designed by Katrina, a 7-year-old girl! The whole story about how she used empty toilet paper rolls to build her Kindle-phone-tablet holding device is in the video below. It's told by her older brother Chris who made getting this device to market his Capstone Project for his MBA. The iCaddy is designed to hold your tablet or smartphone while you're working, playing or viewing a movie. So you never have to go looking for them, it also has a place to safely carry headphones, and headphones with a mic are included. But wait, there's more!
Tom got a Google Nexus 6, but the image stabilization in the camera doesn't work, and Motorola (who made it) and Google won't support it. Leo says that Motorola doesn't support it because Google sold it to a company in China, and It's one of the sad things about the phone industry. Leo says if you can return it, do so and get the Motorola Moto G6.
Tom bought an unlocked Samsung Galaxy S9 while he was travelling and now that he's back, it won't support WiFi calling. Leo says that Verizon supports VoLTE, so contact Verizon and ask them to turn on HD Voice. Tom can also turn it on with the MyVerizon app or the Verizon Account page.
Mike got an iPhone from his daughter and wants to know how to use it. Leo says that the first thing he needs to do is remove it from Find my iPhone (using her iCloud password), then wipe it. Once that's done, he can reset the iPhone and insert a new SIM. Here's how - https://support.apple.com/en-us/HT201252
Leo bought the Samsung Galaxy S10+, a phone with 10TB of storage, 12GB of RAM, and a ceramic back. For $1500. Leo says it's a really nice phone. Reviews are mixed, but buyers seem to like it, with preorders doubling the last generation. Samsung has avoided "the notch," but instead, they have a "hole punch," which houses two selfie cameras. Is that any different than the notch? Not really. It's also nearly as big as the Note 9 and has the best screen on the market. But Leo says it's so fast that it's hyper-responsive. It reacts to being touched on the edge.
Robert is wondering if he needs to get an Antivirus for his smartphone. Leo says it would be unnecessary since the phones' Operating Systems are already quite secure thanks to Apple and Google's efforts. An Android device, for example, will scan apps downloaded from the Play Store (which is the best a 3rd-party app can do anyway).
Ken has Android and he's having issues with Chromecast. Leo says that Ken's smartphone is fairly old, running Android 4.3 (too old for Chromecast compatibility). So he'll need to get a newer device under his budget of $300. Leo says that his current favourite budget smartphone is the Motorola Moto G6. He can get them unlocked directly from Motorola for under $200. Google Fi is selling the G6 for $99.
Samsung recently announced the Samsung Galaxy Fold for nearly $2000, and now Huawei has a Mate X tri-fold mobile device for $2600!
Leo says that folding phones are a feature looking for a market. Do we really want a folding phone? Not at around $3,000. We want more screen real estate, sure. And really, the only way to get over 7" on a mobile device is to fold the screen. But Leo suspects they will break very easily as time goes on. Leo also says that Huawei's model is DOA since it's been banned from the US market due to spying concerns.
Mike wants to know how to jailbreak his Android phone. Leo says that jailbreaking is for the iPhone and it's not recommended because it exploits known security flaws, which is dangerous. The Android phone equivalent is "rooting" which enables administrator access. This allows one to put other firmware on there. But the Samsung Galaxy mobile phones are very difficult to root because Samsung doesn't want users to. But if users go to XDA Developers and input the exact model of their phone, they can find out how to do it.
David is getting his first smartphone, and is buying a Samsung Galaxy J3 V. Leo says that while technically, it's a smartphone, it's one of the lower end ones. It only has 16GB storage, for instance, which isn't much when you consider the room being eaten up by the operating system. It's also probably not up to date with the OS either. Look to see if the system is updated in the settings. Leo says to get it updated as much as he can. If it has support for microSD cards, then he can add extra storage for music and pictures.
