Would keeping my phone in Airplane Mode expose me to less radiation?

Episode 1478

Veronica from Aptos, CA
Person with cell phone

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.

Should I use Wi-Fi calling with my mobile phone?

Episode 1476

Neil from Phoenix, AZ
iPhone Wi-Fi Calling

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.

Phone Radiation Can Cause Cancer in Rats, New Evidence Shows

Episode 1475

Cell phone in the dark

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 from Temecula, CA
Woman using smartphone

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.

How can I recover deleted photos from my Samsung Galaxy Note?

Episode 1474

Russell from Desert Hot Springs, CA
Samsung Galaxy Note 5

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.

Is there an undo command on the iPhone?

Episode 1474

Rob from Lolo, MT
iPhone Undo Typing

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.

What should I buy for my first smartphone?

Episode 1474

Richard from Tampa, FL
Apple iPhone SE

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.

Why can't I use the FM chip in my phone?

Episoide 1473

Todd from Torrance, CA
Radio

Todd loves his Motorola Moto mobile phone because it has an FM receiver in it. Leo says that it's built into the Qualcomm chip set, but most manufacturers don't enable it, or actually disable it. That's because the phone companies want people to stream music and use data, rather than get it free over the air. Why don't phones have AM chips in them? Leo says that noise would probably prevent that.

Is the iRULU smartphone a good option on a budget?

Episode 1472

Joe from Tampa, FL
iRULU Smartphone

Joe wants to know more about the iRULU smartphone. Leo says it's a cheap, $169 phone and he's wary on cheaper gadgets because he'd get what he pays for and it's usually underpowered, easy to break, and limited in the apps he can use. Chances are, it won't be regularly updated. If he needs a good budget phone, Leo recommends the Motorola Moto G5 Plus.

But it's true that smartphones are too expensive these days.
