Google Assistant is coming to your Android phone soon
Starting this week, smartphones running Android 6.0 Marshmallow and Android 7.0 Nougat will be getting an OTA update for Google Play Services that will enable Google Assistant.
It is currently unclear whether every single smartphone out there running Android Marshmallow and up would fit the bill to receive the update, but one thing we know for sure is that, in order to use Google Assistant, you must have Google Play Services installed on your device. This means that Android smartphones from certain regions that are not supported by Play Services will not be receiving Google Assistant.
Also expect to see a lot more Android smartphones launching with Google Assistant from the get-go.
