Samsung Galaxy S7

Cathy has an old Samsung Android phone and she's ready to upgrade. She wants to know if getting a previous model from eBay a good idea. Leo says that she can get a good deal on one, but chances are it won't be updated. So she'd have to have it updated. Leo advises going to XDA Developers to learn how to root the phone to put a new version of Android on it.

How can she transfer over all her photos and contacts? Leo says to tie the old phone to Google Contacts, Calendar and Photos. Then she can just log into her Google account on her new phone and it'll populate all that data back.
