This episode of Android Bytes, we're talking about mobile app security. Android has a lot of robust, built-in mechanisms that protect against exploits and security vulnerabilities, but there's only so much it can do to protect against misuse of sensitive permissions and APIs. Google augments Android's protection mechanisms with Play Protect, a service that looks out for potentially harmful applications.

Brian Reed, Chief Mobility Officer from NowSecure, joins us on the show to explain how Android and Google Play Protect work together to secure your device.
