Don't Install If You're Unprepared
There's no way to predict how Android Pie will perform on your Note 8. Some of you will see a boost, others will run into issues. This is why you need to prepare for the move.
We've put together a step-by-step guide that will walk you through the process we use before we install new Android software on our devices.
If you use your Galaxy Note 8 for work, we highly recommend checking in with your IT department (if you have one) before you install the update because it could have an impact on the apps and services you rely on to do your job.
If you don't have a lot of time to commit to the pre-installation process be sure you check all of your backups. Data loss issue are rare but there's always a chance something gets fouled up.
