If you don't want to sit around waiting for the Over-the-Air (OTA) update you can manually install the firmware on your Galaxy J8 or Galaxy J6 right now.
If you're interested in manually installing Android Pie today, you should get familiar with the installation process.
If the process seems too complicated for your skill set, sit back, relax and wait for the update to hit your phone OTA.
