Most People Should Wait for the OTA
If you're getting impatient, we don't blame you. If you're feeling antsy, you might be thinking about installing the Galaxy S8 Android Oreo update right now. We don't blame you for that either.
Installing leaked software is a good way to get familiar with new software and test performance, but it's not for everyone.
If you rely on your Galaxy S8 to get you through a full day of school or work, you should stay put on official software. The last thing you need is for your apps, services and performance to go haywire on you.
Now that the update is moving out in Europe, North America, and other regions, you should just sit back and wait for the official software to arrive.
