When is Android 9.0 coming out?
A consumer preview of Android 9.0 will most likely be announced during Google I/O 2018, which we expect to take place in mid-May, potentially 16-18 May 2018. As before with Oreo the developer preview was announced earlier in March.
A few public betas will follow, and we expect to see the final consumer release in August 2018.
When will my phone get Android 9.0?
Although Android 9.0 will be released in August 2018, it won't be immediately available to all Android devices. The update will first be available to Google Pixel devices, and then we'll start to see new phones arriving with Android P out of the box at September's IFA 2018 show.
Android updates are rolled out by phone manufacturers and network operators rather than Google itself, because any Android updates must first be tweaked to work with any customisations they have made.
Those with vanilla interfaces - such as Nokia, which has already confirmed Android P updates for all 2017 phones - will be among the first to roll out the update, then the likes of Samsung, LG, Sony and HTC will begin rolling out Android 9.0 in late 2018/early 2019.
OTA updates, when they do arrive, are expected to download and install faster and use less data thanks to Google's Brotli compression algorithm.
There's also no guarantee that your device will be updated to Android 9.0 (see how to update Android). Device fragmentation is still a problem for the OS, and at the last count (by Android Developers) on 5 February there were still devices running version 2.3.3 Gingerbread.
What new features to expect in Android 9.0
According to Android Developers, key new features in Android P include:
Simplicity, speed, and many new ways to extend your apps
MessagingStyle and other notification updates
ImageDecoder for bitmaps and drawables
Data cost sensitivity in JobScheduler
Display cutout APIs
