Use the Location & Security settings to configure how you want the tablet to determine your location (this affects accuracy) and how you want to share your location with Google and others. You can also configure settings that help secure your tablet and its data.
Use wireless networks
Check to use information from Wi-Fi and mobile networks to determine your approximate location, for use in Maps and other geographically aware applications, when you search, and so on. When you check this option, you’re asked whether you consent to sharing your location anonymously with Google’s location service, to help improve the service.
Use GPS satellites
Check to use your tablet’s global positioning system (GPS) satellite receiver to pinpoint your location to within an accuracy as close as several meters (“street level”). Actual GPS accuracy depends on a clear view of the sky and other factors.
Use location for Google Search
Check to use include information about your location when you use Google Search, Voice Search, and so on.
Configure lock screen
Touch to configure your lock screen to require a pattern, PIN, or password to unlock your screen, or never to show the lock screen at all. For more information, see Securing your tablet.
Opens a screen where you can set whether you want to display information about yourself (such as your contact information) on the lock screen and where you can enter the text you want to display.
Touch to encrypt the contents of your tablet and to require a numeric PIN or password to decrypt your tablet each time you power it on. For details, see Securing your tablet.
Set up SIM card lock
(Only for tablets that use a SIM card.) Opens a screen where you can configure the tablet to require entering the SIM PIN to use the tablet, and where you can change the SIM PIN.
Check to briefly show each character of passwords as you enter them, so that you can see what you enter.
Opens a screen with a list of the applications you have authorized to be administrators for your tablet. This is typically an email, calendar, or other enterprise application that you granted this authority to, when you added an account hosted by an enterprise service that requires the ability to implement security policies on any devices that connect to it. Touch an application in this list to disable its authority to be a device administrator; if you do, the account you added will typically lose some functionality in its applications, such as the ability to sync new email or calendar events, until you restore the application’s authority as a device administrator. Applications whose device administration authority you disable in this way, but that have accounts that require them to be a device administrators, typically notify you how to restore their authority when you try to use them, unless you delete those accounts.
Use secure credentials
Check to allow applications to access your tablet’s encrypted store of secure certificates and related passwords and other credentials. You use credential storage to establish some kinds of VPN and Wi-Fi connections, as described in Connecting to networks and devices. If you have not set a password for the credential storage, this setting is dimmed.
Install from storage
Touch to install a secure certificate from your tablet’s storage, as described in Working with secure certificates.
Opens a dialog where you can set or change the password for your secure credential storage. Your password must have at least 8 characters. See Working with secure certificates.
Deletes all secure certificates and related credentials and erases the credential storage’s own password, after prompting you to confirm that you want to do this.
