The Google Assistant is now rolling out to all eligible devices running Android Marshmallow and above. If you just can’t wait to get the update, follow this quick guide to get it right now.
First you will need to update the Google App and Google Play Services. Simply click here and here to get the newest versions of both apps. The linked files must be installed manually so simply tap on the downloaded items and install the updates.
Next make sure you have set one of the compatible languages as the display language for your phone. If you aren’t sure which languages are supported, click here to check. Remember that you need to set this for the whole system, not the Google App individually.
The last step is clearing the data of the Google App. To do this open the Settings and navigate to Apps. Find Google and tap on it, select Storage and tap on Clear Cache and then Clear Data. Now simply reboot the device and you should get the Google Assistant after a long press on the home button.
