Samsung is currently testing firmware version N960NKSU3ETD1 and N960FXXU5ETD5 for the Galaxy Note 9 in South Korea and Europe respectively. These are the One UI 2.1 updates that Samsung confirmed the development on last week.
By paying attention to the firmware version number, you can easily understand that this is a significant update. The Galaxy Note 9 is currently running on firmware version N960FXXU5DTCA in Europe. The next update being tested for the device is N960FXXU5ETD5.
Notice the change of the alphabet D to E? When the alphabet moves up by one place, it’s a signal that this is a major update. New Android OS versions always get a new alphabet and so do significant feature updates like new One UI versions.
