Earlier in the month, Google's team Android released the new v4.4.3 KitKat update to company's Nexus affiliated devices. Now OEM (Original Equipment Manufacturer) partner Samsung is gearing up to rollout the firmware to the company's flagship devices.

Technology blog, Android Geeks, has gotten hold of the alleged internal documents of the Samsung's software testing team, revealing schedules of the next OS update slated for marquee devices. In the report, we see that Samsung has finished the software testing for Galaxy S5 models- SM-G900F and SM-G900H and is set to release firmware 4.4.3 KitKat with build numbers- G900FXXUOBNE6 and G900HXXUOBNE3 to respective devices this month (June).

The company is also on the verge of completing the final phase of the software testing for the 2013 model Galaxy S4 and if things go as planned per the document, Samsung is expected to release the new firmware (build number: I9506XXUQDNE4) for GT-19506(LTE+) model in July. The leaked document only reveals status of software testing details for these three devices but there is no word when the other flagship smartphones such as Galaxy Note 3 and newly released Galaxy devices would receive latest Android software.

For the uninitiated, the new Android v4.4.3 KitKat is not a major software update, but rather a stability firmware with bug fixes and minor enhancements in security and performance tweaks. It has been released to Nexus 5, 4 smartphones and Nexus 7 (2012 & 2013 editions), Nexus 10 and Google Play editions of Samsung Galaxy S2, HTC One (M7 & M8) and Sony Xperia Z Ultra models across all regions and also to Motorola's Moto X, Moto G and Moto E (all T-Mobile variants in USA).

So far, Google has not released any official change log detailing the features of the new update, but according to Motorola's official blog, Android v4.4.3 KitKat would bring in several stability, framework and security fixes in addition to accuracy improvements to the power profile of the smartphones, new graphical layout and color palates to enhance the consistency and usability of the phone dialer and an additional camera feature to enhance image quality including better consistency of exposure, more realistic flash coloring, improved photos in low light conditions using front camera, exclusive to Moto X.
