About Android Security
Android provides a multi-layered approach to the
security.
Prevent: Apps on Google Play are scanned
continuously to block harmful apps and policy
violators. You can also choose to have apps
installed from other sources verified.
Control: App sandboxes prevent apps from
accessing other parts of your device's operating
system, or each other, unless you give permission
during installation. Screen lock and encryption
prevent unauthorized access to the entire device.
Defend: Once identified, dangerous apps can be
removed remotely.
