HMD Global officially rolls out the Android Oreo v8.0 stable update to the Nokia 3 units. The update is rolling over-the-air as we speak and you will soon be seeing a notification to download the software update.

Back in February 2017, the device was initially launched with Android Nougat v7.0 pre-installed and now the Oreo update has started seeding.
A couple of weeks back, Nokia 5 and original Nokia 6 units got the Android Oreo v8.1 update and now only the Nokia 2 users have left with Nougat.
Before downloading the update make sure your device is charged up to 80 percent and is connected to a decent internet connection.
