The most notable of these is the Galaxy Note 8.0, which debuted almost a year ago with Android 4.1.2 (Jellybean). Both it and the Galaxy Tab 3 7.0 will be moving up to Android 4.4 (KitKat) if a report from Phandroid is correct.
There has been no word of similar upgrades for the other models in the Galaxy Tab 3 series, or the very popular Samsung Galaxy 10.1 (2014).
While most people welcome system software upgrades, KitKat has little to offer tablet users, other than marginally better performance and some user interface tweaks. Still, the Android OS is heavily fragmented, with just 2.2% of device owners on version 4.4, so more people moving to the most recent version would be good news for third-party software developers.
