Ezekiel has a leftover phone that he uses as an mp3 player. It isn't activated and all he can use it for is an mp3 player. Leo says that even if users haven't activated it, they can still connect via WiFi. And they can also download it. At the least, I Heart Radio is caching the show while Ezekiel is listening to it, making it local to his device.
Tom's Samsung Galaxy S4 is having issues connecting to his computer without KIES. Leo says he won't really need it, since he can go into the settings and select MTP or PTP mode. The former is for mass media and the latter is Photo transfer protocol. Also, he should check the autorun settings. The chatroom also suggests replacing his USB cable.
Veronica wants to know if keeping her phone in Airplane Mode will expose her to less radiation. Leo says yes, it would. Can she also use Wi-Fi calling? Leo says it's better, but there's no evidence that it will or won't be harmful. The radiation would come from the cell phone radio, not the Wi-Fi. Using headphones instead of putting her phone up to her ear is also better.
Neil traded up his iPhone 8 Plus to the iPhone X, and he wants to know if Wi-Fi calling is a good idea. Should he turn it on? Leo says that the cell carriers would like him to use it if they support it. It doesn't use their towers, eliminating congestion, and they can still charge him for usage. Would it be of any benefit to Neil? Leo says not really. Quality will vary and if he has a poor connection, that could be an issue.
We now have evidence that cell phone radiation can cause cancer in male rats. It is not cause for concern yet, as we are waiting for recommendations from the FDA and others. As always with these kinds of studies, the rats were exposed to a lot of radiation over two years. The original federal studies from the US National Toxicology Program, which uses labels to suggest how strong the evidence is, labeled the evidence "equivocal." That's the second lowest on the scale that the NTP uses, meaning there wasn't enough evidence to really make a connection.
Patty's daughter is going to spend a year in Great Britain. How can she bring along her cell phone? Leo says she could run into serious data roaming charges, so he recommends just getting a local SIM and number. She could check out prepaidwithdata.wikia.com. She may have to get her phone unlocked to do it, but it will work. Some companies like Sprint have a "world plan" but if she adopts it, she may lose the current plan she has.
Russell has the Samsung Galaxy Note 5 and he accidentally deleted his photos off the phone. Leo says that since Roger has Google Photos on the phone, it's likely the photos were automatically backed up. If he's lucky, that's the case. And any photos that have been deleted may still be in the trash can on the phone, where they stay for up to two months. There are some apps that could maybe recover his lost photos, but they have varying degrees of success.
Rob has a friend who's computer died. She tried to use her iPhone to type something and she hit the space bar and it disappeared. How can she get it back? Leo says it may be possible to get it back by shaking the phone. The iPhone has a feature that if she shakes the phone, a popup will appear that says "undo typing?" But the text must be available in the clipboard for that to work.
Richard is looking to get his first smartphone. Leo says the most important question to ask when getting a first smartphone is what phones his friends and family use. He should find out what carriers they have and how happy they are with them. Apple's iPhone makes an ideal first phone because it's so easy to use, but his friends and family will be his first line of support when he's learning to use it. The iPhone is a bit pricey and there are some good budget Android options out there.
Garth turned on his phone and it suddenly started download information into his contact list. Where did it come from? Leo says that smartphone contact lists often go into social networks and sync information to the contacts list. Facebook, Twitter, and LinkedIn all have that feature.
