From the home screen, swipe down the Status bar.
Note: In order for device protection to work correctly, you should configure a Screen lock:
Device protection is automatically enabled when you add a Google account.
If a Google account has not been added, you can add one by tapping ADD ACCOUNT, then tapping Google, and following the steps to sign in to or create a Google account.
Removing your Google account will disable Device Protection.
To remove a Google account, tap Google.
Tap the Menu icon, then tap Remove account.
Note: If more than one Gmail account exists on the device, tap the account name, tap the Menu icon, and then tap Remove account.
To confirm, read the warning and tap REMOVE.
Note: If prompted, enter the unlock code for your device to continue.
Repeat the steps for all the existing Google accounts.
Device Protection is now disabled.
