Currently, the Google Pixel 3/3XL, Pixel 2/2XL and the Essential Phone are getting the official Android 9.0 Pie update. Nokia 7 is currently under the Android Pie beta update and a majority of other devices are getting the Pie ROM unofficially.
The new version of Android OS comes with improved features and security as compared to the Oreo update.
As mentioned, a majority of devices have started getting ported Android Pie because they support Project Treble. The Project Treble was launched by Google for OEMs to port newer Android versions to their devices.
But third-party developers took it for Custom ROM developments and the result is now before us.
