Don't Install If You're Unprepared
Those are a few reasons to think about installing Android Pie right away on your Galaxy S9 or Galaxy S9+. Here are a few reasons to consider holding out.
It's extremely difficult to predict exactly how the Android Pie update will impact your Galaxy S9's performance. Some of you will see a boost but many others will run into problems.
The Galaxy S9 Android Pie update went through extensive testing, but problems have (unsurprisingly) slipped through the cracks into the final build.
This is precisely why you'll want to prepare your device before you upgrade to Android Pie. Some prep work could go a long way toward preventing headaches.
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 S9 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 you should, at the very least, make sure all of the important data is backed up.
You can use Smart Switch, Samsung Cloud, or another service to do this.
