Don't Install If You're Unprepared
If you aren't prepared for Android Pie, hold off on the installation.
We've put together a step-by-step guide that will walk you through the process we used before we installed Android Pie on our devices.
If you use your device 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 use at your workplace.
You'll also want to install app updates, charge up your device, and get familiar with all of the smaller changes on board the Android Pie upgrade so you aren't caught off guard.
If you don't have a ton of time to devote the pre-installation process, just make sure all of your important data is backed up before you make the move.
