Can I make an image backup of my mobile phone?

Episode 1429

Bob from Philadelphia, PA
Helium Backup

Bob has a dual SIM mobile phone with T-Mobile and he's having trouble going from one number to the other. He couldn't receive calls. He's tried to go to T-Mobile and has also done the factory reset and now he can get calls. But he's lost all his data. Can he get it back? Leo says the safest way to protect his data is to backup his data to his Google account. He can do this by going to "Backup and Reset" in settings. Then he could automatically restore it. This would save his settings, apps, and contacts, but it won't save his music or photos.

Why does downloaded music disappear from my phone?

Episode 1426

Ron from North Hollywood, CA
Astro File Manager

Ron has a Samsung Galaxy Note 4 and he's been emailing himself mp3s he makes in the recording studio. The phone holds onto the file for about a day, and then it disappears. Leo says it sounds like the download goes to his cache, which gets cleared out. Leo recommends using an app that will enable him to move it once he downloads it. Samsung's File Manager app will let him see that folder.

Apps to Help Track Purchases and Subscriptions

Rich DeMuro filled in for Leo Laporte this weekend, and recommended a couple of apps that will help you make purchases and track them. First is an app called Earny. This tracks purchases that you make at major retailers and looks for price drops. Prices change all the time, and we typically check prices before we buy things, but not afterwards. If Earny sees a price drop on a recent purchase, it will collect a refund for you by reaching out to the company. The pro to using this app is obviously the cash you'll get back from purchases.

What app should I develop next?

Episode 1425

Joe from Gardena, CA
Apple iOS 11 App Store

Joe is an app developer and is looking to create an app for AR. Since Joe already has a parking app he's developed, Rich thinks he should elaborate on that and use the phone's camera to decipher parking signs. A user could simply point his or her camera at the sign, and the app could return a big check mark or red 'x' on if it's ok to park there at that time. The issue will be gathering the information for the backend. But if he can make submitting data easy and fun, and it works, then he'll have a winner.

Why is my iPhone using so much data?

Episode 1418

Bill from Simi Valley, CA
Apple iPhone 7 Plus

Bill has a family plan with Verizon and one of his kids has been using up most of the data resulting in three overage charges. The problem is, he doesn't use it much. Leo says he'll need to look at the phone and see what it says. He should look at the cell usage in the settings. If it roughly matches, then there's something that the iPhone is doing that is burning up bandwidth. The good news is that he can look at the data usage by app in the iPhone's settings.

Why doesn't Uber know where I'm at?

Episode 1417

George from Santa Monica, CA
Uber for iOS

George uses his iPad to call Uber, but they don't know where to pick him up. Leo says that's because the iPad doesn't have GPS. The app just has to ask for the address of where he is in order to find him. With a mobile phone, they would have his coordinates in the app. Without GPS, the app has to use other means to find his general location, usually it uses "WiFi triangulation," and that's not always very accurate. The app puts a pin where he is, and if it's using WiFi triangulation, the pin just goes close to where he is. The good news is he can move the pin in the app.

How can I prevent anyone not in my contact list from calling me?

Episode 1412

John from Santa Monica, CA
Truecaller

John wants to know how he can limit the number of calls on his mobile device to only his contact list. Leo says that's called White Listing and since we're now being bombarded with spam and robo calls, that would be a very good idea. Google Voice can do it, but he'd need to get a new number. He can forward his number through it and Google Voice will then filter out unwanted calls, though.

Will Waze work with Apple's CarPlay?

Episode 1411

Corey from San Pedro, CA
Waze

Corey wants to know if Waze can be used on her Hyundai's Android Auto screen. Leo says Waze just got out of beta for Android Auto. But Corey has an iPhone, which uses CarPlay. He knows that Waze is in beta for CarPlay, but it's a bit tricky to install it. Check out Carplaylife.com for tips on how. Currently, it won't display on CarPlay, and Google has no plans to do so.
