The system has build number R220XXU1ATK5 and weighs only 0.7 MB. Nevertheless, many small but useful changes have been added to the firmware. For example, the developers have fixed bugs and also improved the system and the motion sensor. It should now better recognize the state of the user. Even after the update, the watch will stop switching to the dial every time the screen goes out. The bracelet will also vibrate longer during the alarm.
The update has only been released for Galaxy Fit 2 users in India so far. In other regions, the firmware will appear a little later.
