While Google Assistant is baked into core of the new OS versions, for the above mentioned older versions users will have to launch Google Assistant app to start using its features. Google is also rolling out to the Assistant to users in Italy, Japan, Germany, Brazil and Korea.
Google Assistant, the aptly named personal assistant found on Android devices (as well as the iPhone but hey, that's the least of our concerns, really), has been available to most users for over 9 months now. Google says that once users receive the update and install it, they will see the Assistant app icon on the "All apps" list.
Having Android Oreo work well on both high-end flagships and low-end budget phones is no easy task.
Meanwhile, Google is expanding the feature to more phones by adding support for 5.0 Lollipop.More news: Several injured in major gas pipeline explosion outside Vienna

Google Assistant is also intuitive enough to learn the behaviour of the device owner over time and improve its service.
Announced back alongside the first generation Pixel smartphones, Google Assistant was exclusive to Pixel devices.
The Google Play Store will also highlight the lighter version of apps, these will show as "optimised for your device" when browsing the store on a budget phone. The Spanish language version is being rolled out to the U.S., Mexico and Spain. Additionally, this update is only available to devices which are running on Android 7.0 Nougat or Android 6.0 Marshmallow. In Google's Chrome browser, for instance, Data Saver can help users conserve more than 600 MB of data per year.
