How can I use Google Assistant?

Please press and hold the home button to enter Google Assistant.

On Android 9.0, Google Assistant adds a more realistic voice-over to provide an improved conversation experience. You don’t need to say "Hey Google" in the conversation now. It can support multiple rounds of dialogue, understand the context, and accurately segment your questions in long and complex sentences, and handle multiple questions and answers. When you say "Please" to it, it even makes a polite response.
