The key to unlocking the Samsung Galaxy S5 screen? Your fingerprint
Samsung's Galaxy S5 has become the latest smartphone to add a scanner that unlocks the home screen after reading your fingerprint.
First things first
You start the finger-registration process by tapping the Finger Scanner icon in the newly-redesigned Settings menu.
Setting up your profile
The Galaxy S5 lets you store three profiles. After tapping to get into the manager window, press the "+" sign to get started.
8 is the magic number
You'll swipe down 8 times to register your print, then set up a backup password in case you get locked out.
Make sure you select "fingerprints" as the screen lock setting.
Straight and narrow
Most of the time, the scan worked for me, but it's important to swipe down vertically from top to bottom -- or you'll get a misread.
