The new option was noticed by a user on Reddit over the weekend.
That means you can hold the home button and pull up Alexa. This is particularly compelling if you own an Amazon Echo at home, where you might already be used to using Alexa to check the weather, play the news or add goods to your shopping list.
I'll show you how.
After you've followed the steps above, you'll see a prompt to talk to Alexa instead of Google Assistant. It'll ask for permissions, so tap "Allow" to let Alexa hear your requests, call and message family members, control devices in your smart home and provide location-relevant search results.
That's all there is to it. Now you'll be able to hold the home button to pull up Alexa. You can use Alexa to turn on smart lights at home ("Alexa, turn on the living room lights," for example), order products from Amazon by voice ("Alexa, order soap") and more.
