Help configuring Roku device settings, using Roku OS features such as screen mirroring, adjusting display type and audio settings, using Guest Mode, and assistance with software updates.
When an update is available, the Roku will auto-update itself. This includes both OS and channel updates. Of course, you can manually do a update check in the Settings/System/System Update menu.
But if you're looking for firmware 9.3, be aware that Roku doesn't release it to all players at the same time. They use some internal (and unknown to the users) schedule for what players can get the update, and what geographical locations can get it as well. This way on the off chance there's something seriously wrong with the update they haven't messed up the entire world. 
So they do a slow, gradual rollout.
