Samsung Galaxy S4 and Note 3 to get KitKat in January
A newly leaked schedule reveals which will be the first Samsung devices to get Android 4.4 KitKat. As you could expected the first to get the new Android version are this and last year flagships - Galaxy S4, Galaxy Note 3, Galaxy S III and Galaxy Note II.
Samsung's Galaxy Note 3 and Galaxy S4 will get the KitKat treatment just two months from now - in January, 2014. The 2012 ex-flagships Galaxy Note II and Galaxy S III will be getting KitKat in March or April 2014.
The new Android 4.4 KitKat improves the UI performance thanks to its Project Svelte - the successor of Project Butter. This means all devices to be update with KitKat will become smoother and faster than ever, with even better multi-tasking and improved RAM management. We are sure Samsung will bring a few goodies to its TouchWiz UI, too.
There is no official confirmation on the roadmap and we can't verify if this document is indeed the real deal, so you should take this info with a healthy pinch of salt.
