Decide How to Install Android Oreo
The Samsung Galaxy S7 Oreo update will likely take several weeks to finish up. If you're an impatient person, you might not want to wait for the Over-the-Air (OTA) update.
If you don't want to wait for Samsung or your carrier to roll out the upgrade, you should be able to manually install the software ahead of time. We expect the Galaxy S7's official Android Oreo firmware to emerge in the near future.
If you're interested in manually installing Android Oreo on your Galaxy S7 or Galaxy S7 Edge, we highly recommend getting familiar with the process right now.
If the manual installation process seems too complicated for your skill set, wait for your Galaxy S7's Oreo update to arrive Over-the-Air.
