Android was built to be very, very secure.

Android was intended to be very customizable. And we welcome innovations.

Android is one of the most open systems I've ever seen. What makes Android great is it's literally designed from the ground up to be customised in a very powerful way.

We do have business relationships; we do licensing relationships, and people want to use Google services on top of Android. But in theory, you can use Android without Google.

Obviously, you will always see more malware targeting Android because Android is used more than any smartphone platform by a pretty substantial difference.

We need to bring Android and Chrome to every screen that matters for users, which is why we focused on phone, wearables, car, television, laptops, and even your workplace.
