Don't Install If You're Unprepared
You can't predict exactly how the Android Pie update will impact your Note 9's performance so it's important to prepare for the worst.
The Note 9's Android Pie update went through beta testing, but problems have made their way into Samsung's final build.
A little prep work can go a long way toward preventing issues so you'll want to spend some time preparing yourself and your device for the move.
We've put together a step-by-step process that will take you through some of the things you should do before you install.
If you use your Note 9 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 need to do your job.
If you don't have a lot of time to devote to this, at the very least you'll want to make sure all of your important data is backed up.
You can use Samsung's Smart Switch, Samsung Cloud, or another service to do this.
