These are the actual Galaxy Note 9 One UI 2.1 firmware being tested

We reported earlier today that the Galaxy Note 9 One UI 2.1 update was one step closer to release. A moderator on Samsung’s official forums for South Korea had confirmed that the update has now entered testing.

We have come across the actual One UI 2.1 firmware versions that Samsung is testing for the Galaxy Note 9 in Europe and South Korea. This should put to rest any concerns that users may still have had that it was too good to be true for the Galaxy Note 9 to be getting One UI 2.1.

Galaxy Note 9 One UI 2.1 test firmware versions

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.

The appearance of these test firmware is a great sign that the Galaxy Note 9 One UI 2.1 update is going to be released in the near future. This also means that it won’t be long now before the same treatment is given to the Galaxy S9 as well. We are keeping a very close eye on this and will let you know as soon as Samsung starts rolling out the firmware update to the public.
