Get Acquainted with Android 8.0 & Android 8.1
Samsung hasn't released a Galaxy Note 8 Android 8.0 Oreo beta and we aren't expecting one ahead of its release. That said, you can still get familiar with the GalaxyNote 8's version of Android 8.0 ahead of the release date.
The Galaxy Note 8 Android Oreo update recently leaked giving select users a chance to try the software early. The leaked firmware is unstable, but it does include many of the changes coming with the official version of the software.
If you own the correct model and you have experience downloading early software, you might want to dig in and test Android 8.0 Oreo. If you don't have any experience, we recommend getting familiar with Android 8.0 in other ways.
One way to do that is via the Galaxy S8 Android 8.0 Oreo beta. We expect the two updates to be similar in a lot of ways so make sure you look into the changes Samsung's featured in the beta.
We also recommend getting acquainted with Android 8.1 Oreo.
Samsung's currently testing Android 8.0, but we could see elements of Android 8.1 eventually make their way to the Galaxy Note 8.
