I have just tried to help a guy who's phone has a broken screen. He needs to get the stuff off of it before the new S5 arrives.
Every S5 needs to have these 3 Samsung tools on it immediately.
This one will allow you to unlock your phone from your PC even if the screen is broken.
* SideSync 3.0 - Android Apps on Google Play
This one will back up your phone's apps and all data.
* Kies | SUPPORT | SAMSUNG
This one will transfer your previous phone's apps and info to your new phone, IF, the previous one is a supported model.
* Samsung Smart Switch
Do this now,

or regret it later if you don't.
