Samsung's Galaxy Note 3 may receive the latest Android 4.4 KitKat OS update very soon.

According to GottaBeMobile, the Android 4.4 KitKat OS update is now on the testing phase and will most probably be rolled out in the near future. The report was tipped off by SamMobile which claimed that Samsung is now working on the OS upgrade. Samsung Galaxy Note 3 was released running with the 4.3 Jelly Bean OS.

Rumours also suggested that Samsung Galaxy S4, S3 and Note 2 will receive the Android 4.4 KitKat OS update although the company has not confirmed anything yet. Currently, Samsung has not released a timeline and estimated time of arrival of the update. However, this is a sign that Samsung is hard at work on the software upgrade.

Samsung smartphones such as the Galaxy S3 and Galaxy Note 3 may receive the Android 4.4 KitKat OS update next year after the announcement of Samsung Galaxy S5. It is speculated that the rumoured Samsung Galaxy S5 will be the first smartphone to receive the KitKat OS aside from the Samsung Galaxy S4 Google Edition.

The Google Play edition of the Samsung Galaxy S4 will be the first Samsung handset by the end of November as the device is running in pure Android software. Android 4.4 KitKat OS was released alongside the new Google Nexus smartphone - Nexus 5 on Nov. 1. Google also announced that Nexus 4, 7 and 10 as well as Google Play Edition smartphones are the first to receive the KitKat software update.

Some of the changes that the Android 4.4 KitKat OS brings are new Android interface dubbed as translucent bars as well as an updated Phone app, which adds integrated searchable contacts, directories in other Google apps, and even nearby businesses.

Android 4.4 KitKat OS also comes with "immersive mode" that will hide all of your other open elements to allow you to focus on the content you are actually using such as when you are watching a movie or reading a book. A revamped Hangouts app will also throw all of your text messages and video calls into the mix, so you are not backing out to find them in another app.
