The first September security update has been released by Samsung, and it is being rolled out to the Galaxy Note 9 as we write this. Given Samsung's tendency to push out new security updates well ahead of time, you could technically say the company is late with this month's release, though the floodgates should now be open and we should see the September security patch making its way to more Galaxy devices in the coming days.
The Galaxy Note 9 is receiving the update in Germany at the moment and getting a bump up to firmware version N960FXXS6ETHB. The update is available over the air, so you can download it from your phone's Settings » Software update menu by tapping the Download and install option. You can also download the complete new firmware from our archives and install it on your phone manually using a Windows PC.
No new features in this update, but One UI 2.5 is on the horizon
The September security update for the Galaxy Note 9 doesn't have anything other than improved security to offer, but owners of the device can look forward to some new features in the next couple of months as Samsung has confirmed that the Note 9 (along with the Galaxy S9/S9+) is eligible for the One UI 2.5 update. It is not known at this point just how many One UI 2.5 features will make the cut, however. Wireless DeX support will hopefully be included, seeing as how it seems to be the most coveted feature based on the comments we have seen here on SamMobile.
