The previous firmware update for the Samsung NX1 was quite significant, but Samsung is far from done with the Tizen based NX1 Smart Camera. This morning version 1.40 has been released and is a 308Mb zipped download. We have improvements in continuous shooting, Improved Zoom AF and other enhancements and bug-fixes.
Many professional photographers have commented on the blazing speed of development and the rapid releases of firmwares for the NX1. Samsung has full access to the Tizen source code and as such are not hindered by companies limiting access, like is the case with Android.
You can use iLauncher to update your Smart Camera or download the firmware file to your SC Card and update. All download files can be found here. Note: Please make sure that all files are suitable for your Operating System and location.
