How to Change the Screen Lock Setting on Your Nexus 7
You can secure your Nexus 7 from access by evildoers in a number of ways. The first method is to employ a lock screen, specifically one better than the standard sliding lock that the Nexus 7 uses. The second method is to use data encryption on the tablet’s contents. Finally, you can take advantage of the Owner Info text.
Lock screen security is set on the Choose Screen Lock screen. Here’s how to get there:
At the Home screen, touch the All Apps button.
Open the Settings app.
Choose Screen Lock.
If a screen lock is already set, you must trace the pattern or type the PIN or password to continue.
The Choose Lock Screen window lists six types of lock settings:
None: The screen doesn’t lock. Even the Unlock-button-and-locking-ring thingy doesn’t show up. Choosing this option disables all locks.
Slide: The Nexus 7 simply uses the standard locking screen: Slide the Unlock button to the unlocking ring.
Face Unlock: Use the front camera on the Nexus 7 to use your adorable face as the unlocking mechanism.
Pattern: To unlock the tablet, you must trace a pattern on the touchscreen.
PIN: The Nexus 7 is unlocked by typing a personal identification number (PIN).
Password: You must type a password to unlock the Nexus 7.
