Android 4.4 KitKat upgrade: Samsung Galaxy S4 and Note 3 update on January while Galaxy S3 and Note 2 on March

Almost all the manufacturers have now started to roll out the latest Android OS by Google, the KitKat 4.4.2, to their respective devices.

It has already been confirmed by HTC that its flagship smartphone HTC One will receive the software update on all the major US carriers by the end of this month.

Last month LG had rolled out the Android 4.4 OS to some of the LG G2 users in Korea but it was just a sample update with only a few users receiving it.

However, it is expected that within this month LG will be rolling out a mass update but till now no specific dates for international models has been confirmed.

All Nexus devices including the Nexus 4, 5 and 7 received the Android update almost as soon as it was launched and this was followed by rolling the update to non-Nexus Google Play Edition smartphones. Even the Moto X, Moto G and the Moto Droid series received the update last month.

Samsung has till now not released an official schedule for the update rollout to the Galaxy S3, Galaxy S4, Galaxy Note 3 and the Note 2 devices.

Galaxy S4 Google Play Edition is the only Samsung device to release the update till now. However, iTechAddict has released an update schedule for some the latest Galaxy S4 and note 3 devices which states that the update may be rolled out this month itself, while the Galaxy S3 and Note 2 may receive the update by March.

It was also announced by French carrier SFR that the Galaxy S4 and Note 3 will receive the update by the end of this month. For other who cannot wait till the official roll out of the update, they can install Android 4.4 through a custom ROM but at their own risk.
