On Android devices with Google Mobile Services (GMS), the Google application is pre-installed, and consequently, the Google Assistant is also pre-installed, which is a digital assistant that you can rely on to receive information on weather, traffic, events, sports scores and more simply by holding down the Home button. However, those who have started to get to know Alexa, Amazon’s assistant, because they perhaps use it at home on Echo devices, have had to install the Amazon Alexa application on their smartphone to manage everything via Alexa. Well, those who have installed the Amazon Alexa app on their smartphone can choose to have Alexa as the default voice assistant on their smartphone instead of Google Assistant. So in this guide, we will tell you how to set Alexa as the default digital assistant on your Android device.
How to Set Alexa as the Default Assistant on Android (2023)
It is very easy to set Alexa as your default digital assistant on your Android devices, just follow the steps given below.
- First, you need to enter the Settings of your Android device.
- Then look for the option to customize the Home button (physical or virtual doesn’t matter) for when you hold it down and enter.
- On Samsung Galaxy phones the steps to follow are Settings > Advanced Features > Phone Assistant App: here you should find three options such as None (if you don’t want to activate a digital assistant when you press and hold the Home button), Google (to recall the Google Assistant), Alexa (to call the Amazon Alexa Assistant).
- By default Google should be selected, so simply press on ‘Alexa’ to switch the setting; you will be asked “Set Alexa as an assistance application? The device assistance application can display the applications used and related information,” then press Accept.
- The device may also ask you to give Alexa permission to access the microphone, you must accept otherwise it will not be able to hear the commands and therefore carry out what is asked of it.
We remind you that it is also possible not to call an assistant by pressing and holding the Home button: to do this, simply select ‘None’ on the device assistance settings page.
As an alternative to holding down the Home button to call up Alexa, the ‘Alexa’ widget is available from the Amazon Alexa app which can be inserted as an icon on a home screen which, when pressed, enables listening to Alexa. This widget can be added like any other widget.
Once you have granted Alexa the necessary permissions, simply press and hold the Home button (or press the widget on the home screen) to see the bottom of the screen light up blue (equivalent to the blue circle on Echo devices to signal that Alexa is listening) to ask you to do things like call and text friends and family, control compatible smart home devices, get search results, traffic and weather information, and more. By releasing the Home button (or pressing the X that appears at the bottom of the screen) Alexa stops listening.
And that’s all there is to know about how to set Alexa as the default Assistant on Android. While you are here, check out our other Android Guides here: Fixing Google Apps Crashing on Samsung Galaxy Android Devices, and Changing App Icons on Android.
