The Nexus 5 will feature this new O.S. out of the box and other Nexus devices including Nexus 7, Nexus 10 and Nexus 4 will also receive this update in the coming weeks but these new updates won’t give you the full KitKat Experience as in Nexus 5. The cool KitKat launcher which launches Google Now when you say “OK Google” won’t make it to the other nexus devices. The Samsung Galaxy Nexus won’t get KitKat update either. The reason for this is not official, but it might be due to tech issues with old OMAP chipset in Galaxy Nexus. Also it lies outside the 18 month purview for promised Android OS updates by Google. Sony has announced its Road Map for phones which will see KitKat OTA update. These include Xperia Z, Xperia Z1, Xperia Z Ultra, Xperia Tablet Z and Xperia ZL. Many of the Xperia devices are not yet done with Android 4.3 KitKat update and thus if you own one of these smartphones, you won’t be seeing a KitKat update on it anytime soon. Android 4.4 KitKat support will soon roll out globally for LG G2, the new flagship phone from LG. The HTC One along with its various variants will also soon get the Android 4.4 update in three months or less. The roll out expect to start after the mid of January 2014. There is no word on the Android 4.4 update for LG Optimus G Pro and LG Optimus G as of now. The Samsung Flagship devices like, Samsung Galaxy S4 and Samsung Galaxy Note 3 will also receive the Android 4.4 KitKat update in coming months. We are expecting Galaxy S3 and Note 2 to receive this update as well. For noe Samsung is rolling out Android 4.3 update on its 6 popular smartphones in India including To reduce the fragmentation in Android eco system, Android KitKat is light weight and can even work with 512 MB RAM. But will we see this phone in more budget devices soon? That doesn’t seem likely for quite some time. If rumors are to be believed, Micromax might also provide KitKat Update for Micromax Canvas HD, Which sold like hot cakes earlier this year. Ofcourse, the developer community will also take care of popular phones not getting official Updates.
