Once the Android Oreo roll out starts in your region, keep your device charged up. This way, you'll be able to install the Android 8.0 Oreo update soon after it arrives, if that's what you choose to do.
Most Galaxy Android software updates require you to have 20% of battery charge to complete the installation process. We recommend keeping a 50% battery charge on your Galaxy A for Android 8.0 Oreo because it's a huge upgrade and will likely take some time to complete. We also recommend keeping a charger close by once your update starts rolling out. That way, if your Galaxy A3, Galaxy A5, or Galaxy A7 doesn't have enough charge, you can plug it in and get the ball rolling.
