If you need to transfer your data from an old phone to a new one, there are a few ways to do it. First of all, check to see if your data is already being synced to the cloud. Data such as email, contacts, and calendars are likely already stored with Google or Apple's iCloud. You can verify this by logging into your Google or Apple account from a web browser and checking to see if the data is there.

Noah's girlfriend lost her smartphone, but they found it and the screen is shot. The phone still works, but they'd like to get the contacts off. Leo says they can connect it to a computer and use the Android File Transfer app on a Mac, or use it as a hard drive on a PC. The PC will read the phone as a hard drive and then they can hunt around and find all the data. She should look in the Android Data folder, check "SD0", copy all of it to the hard drive, and then root around.
