No cable needed-
With a Google account I have switched phones three times and every one is a duplicate of the previous one. When booting a new phone for the first time I set up wifi, enter my Google account and password and a few minutes later I'm ready to go. I went from a Moto X 2013 to another Moto X 2013 to a Blu Vivo XL to a Samsung Tab S2 to a Moto X Pure Edition. I have done a factory reset on two of my phones and doing the above resets every thing as before. No problems.
BUT-
It does not restore texts.
