The new version number is N950USQU3CRD7 and includes bug fixes and performance enhancements. New features found in Android 8.0 include picture-in-picture, which allows users to watch video on the screen while interacting with another app in the background. The update also includes new emoji, notification channels and the ability to snooze those notifications that aren’t about pressing matters. And don’t forget the redesigned settings menu, which has been trimmed down.
When you receive the notification that Android 8.0 is ready to be installed on your T-Mobile Galaxy Note 8, there are two things that you should do prior to starting the updating process. Make sure that you are connected to a Wi-Fi signal, and recharge your battery to 100%.
Since this update is being sent out OTA, it might be a few days before it hits your phone. If impatient, you can try to grab the update manually by going to Settings > Software update > Download updates. T-Mobile also says that to avoid network congestion, a limited number of updates are available daily. If the limit has been reached on a specific day, try again the next day.
