You can't predict what kind of performance you'll get out of Android Oreo. Some of you might see a performance boost while others will run into performance issues. This is why we always tell people to prepare ahead of time. A little prep work will go a long way toward preventing issues.
We've put together a step-by-step guide that will take you through the process we use before we hit install on new Android software like Oreo.
