Samsung are rolling out an update for the international version of their phablet, the Samsung Galaxy Note 3 (SM-N9005).
The update is a minor one, and adds the Download Booster, Kids Mode, KNOX 2.0.
You have to download the Kids Mode which is about 72 MB in size, as the update just adds the installer for it.
The update is around 185 MB in size, and is available OTA (over-the-air), in the UK. It should be rolling out to other regions soon. The build number of the update is N9005XXUFNF4. You can try checking for the update manually by navigating to Settings » General » About phone » Software Updates.
XDA user st3chn0, who first reported the update and posted the screenshots, notes that the update has brought better animations, and improved battery life.
