The time is drawing near for Samsung Galaxy S5 and Note 3 to receive the Android 4.4.3 update.

According to reports, leaked Samsung KitKat update schedule document reflects the update to Android 4.4.3 on the two devices.

This makes perfect sense, since Samsung Galaxy S5 and Note 3 are the Korean mobile titan's flagship devices in their respective market today.

It is also said in the reports that updates for both Snapdragon and Exynos variants of Galaxy S5 have reached the final stage, and are being finalized for release.

However, the document showed that the update would happen late June.

Instead, the latest Android 4.4.3 update was pushed out on Galaxy S3 and Galaxy Mini for Verizon users last week.

If you take a closer look at the alleged leaked document in this GSM Arena report, there are some odd font differences which could indicate it is a bad Photoshop-job.

Tech pundits are now seeing the update coming through in July while everybody is busy talking about Android L, which has been the centerpiece of the last Google I/O developers conference.

Google released Android 4.4.3 KitKat earlier in June, and a number of smartphones and tablets in the Nexus series received the first taste of the updates, including Nexus 5, Nexus 4, Nexus 7 (WiFi and LTE), Nexus 10, Galaxy Nexus, and Nexus S.

The new operating system update brings meager changes such as a visual update to the phone dialer, addition of new colors, and bug fixes for CPU usage and the camera on the Nexus 5.

Factory images were posted in Google's official developers website.

Motorola shortly followed the Nexus updates and pushed the Android 4.4.3 update to Moto X, Moto G and Moto E.

Motorola users saw the following changes in the smartphones: improved camera image quality, better exposure, more realistic flash coloring, improve photo quality in low light conditions and better video recording experience.
