Put a Screen Lock on Your Galaxy S 4
The most basic effort you can take to protect your Galaxy S 4 is to put some kind of a screen lock on your phone. If you are connected to a corporate network, they may have a policy on what you must do if you are to access your corporate network. Otherwise, you have eight choices in increasing degrees of security:
Unlock with a simple swipe across the screen
Unlock with your face
Unlock with your face and your voice
Unlock with a pattern that you swipe on the screen
Unlock with a PIN
Unlock with a password
Encrypt everything on your phone and unlock with a PIN
The first seven options are selected in the Lock Screen option in Setting. The Encrypt everything on your phone has some serious implications, so be sure to look into that option in detail.
If you want to choose one of the first seven options, here’s what you do:
From the Apps Screen, tap the Settings icon.
This should be old hat by now.
Go to the My Device tab.
Scroll down and tap the Lock Screen option.
Tap Screen Lock.
This brings up the options seen in the figure.
Each option prompts you through what it needs before establishing your security selection.
For reasons that sort of make sense, your phone uses some terminology that can be confusing. To clarify, the term Screen Lock is an option you can select to prevent unauthorized users from getting into your phone. The term Lock Screen is short for the action of locking your screen or enabling the Screen Lock option.
