Update build G920FXXU3QOKD Brings VoLTE and VoWIFI Support for GalaxyS6 SM-G920F

Another Android 5.1.1 update for the Galaxy S6 (SM-G920F) that bumped up to build G920FXXU3QOKD has just recently released in the Nordic countries. According to initial changelog details, the G920FXXU3QOKD update mainly brings the Voice Over LTE (VoLTE) and Voice Over Wi-Fi (VoWIFI) support, but also includes some bug fixes and further improvements on to the device performance.  The latter is now the 5th Android 5.1.1 ever rolled out to the said countries so far. This is an update to the previously released build G920FXXU3COI9, but while taking a closer look at the build details itself, this one got a much higher chagelist value as we compare to the last released.

Here goes the details:
  • Android version: 5.1.1
  • Baseband version: G920FXXU3QOKD
  • Kernel version: 3.10.61-5931673
  • Build number: LMY47X.G920FXXU3QOKD


And here's the details of the previous released build;
  • Android version: 5.1.1
  • Baseband version: G920FXXU3COI9
  • Kernel version: 3.10.61-5816106
  • Build number: LMY47X.G920FXXU3COI9

As you may take a quick comparison between the two, you may notice that it is now in-lines with the letter "Q" series. This simply means that it is a special firmware build on some select countries and mobile carrier providers.  Also, the firmware build itself has drastically changed and has moved to a much higher "Baseband" and "Kernel version. Unfortunately, this update is being held available for those who owned the unlocked version of the Galaxy S6, particularly  in Sweden, Finland, Norway, Iceland, Denmark and the rest of the Nordic territories only.

How to Update the Galaxy S6  (SM-G920F) to Android 5.1.1 (Lollipop) build G920FXXU3QOKD


  • Make sure to recharge your phone first.
  • Do not forget to backup all of the important data that were stored in the device memory.
  • Your Galaxy S6 must still run on the official software version and has not been rooted nor installed with non-official firmware.

Updating the Galaxy S6 via Over-The-Air (OTA)


This is the usual method on how to check and to perform an update on Galaxy S6 to the latest software version.  This method is what we called Firmware Update  Over-The-Air and so-called as FOTA or simply OTA update. In most often cases, a notification message will be directly sent out to you by your network provider and by Samsung itself, telling you that there is a new update that has now available for download.  This approach requires you to prepare a strong WiFi connection,  and so it might happen sometimes that one did not receive any software update notification messages; (1) If and when the device is out of range during the software update roll out  period, (2) Automatic update has been turned off in the device Settings.
However, We can still manually check for the update instead.

Here’s how to do it manually:
  • From your Galaxy S6 Home screen tap on Apps.
  • Select the Settings gear icon.
  • Tap About device.
  • Tap Software update.
  • Tap Check for an update.

It will then notify you that a new update is available for download. But it also says that “Your device software is up to date“, and there is no software update is yet available for grab. You can simply choose Download and Install now if you do so or else Install later if you want to get the update in later time.

But if ever you might have had received this message while checking software update that says something like “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.”  This is a warning message that only appears for those devices that have been rooted and installed with modified and unofficial firmware.  So to be able to get the Software OTA update again, you must Unroot the Galaxy S6  first and removed any modification that has been installed on it.
