Nokia Android P update
So, all the Nokia phones launched in 2017 and 2018 will get the Android 9.0 P update whenever available. If you own Nokia 3, Nokia 6 or Nokia 8 smartphone, then you should get the Android Oreo treatment by the end of the year, followed with Android 9.0 update by the end of 2018.
HMD Global as planned are well on target of 6-7 Android phones by the end of 2017. There are no plans right now revealed regarding the Nokia 2018 phones. All the 2017 models are powered by Android 7.0 Nougat out of the box. The Nokia 8 Oreo update has been teased and it could be arriving as early as October 2017.
HMD Global recently confirmed that their phones will receive two major Android upgrades. The updates will be rolled-out via Over the Air download. However, the entry-level Nokia 2 smartphone will stay with the Android 7.0 Nougat and will not even get the Oreo update. You can check out Android Oreo phones list to check which phones will the update or not. The timeline(ETA) is also mentioned over there.
All the Nokia Android phones will also get the intermediate Android 8.1 update (the Android version) too.
This is pretty much follow-up of what Motorola has done in the recent years. The company, now owned by Lenovo provides software update support for two years life cycle.
Normally a new Android version is announced during the third quarter every year. This year too, Android 8.0 Oreo was announced as the successor to Android 7.0 Nougat.
Nokia 2 might not get this update.
Google could start teasing out the Android P update in Q2, 2017 and will announce the version at Google I/O event, held during the month of May or June every year.
