Android 4.4.3 KitKat Update for Samsung Galaxy S4, S5 and Nexus 5: Latest Rumors and Launch Date

May 19, 2014 06:32 PM EDT

Samsung has been testing the Android 4.4.3 KitKat Update on a device believed to be the Galaxy s5, while a recent leak suggests that Google may be rolling out the Android 4.4.3 KitKat Update for the Google Nexus 4, 5, 7, 10 on May 23.

Just last weekend on Sunday, Chinese-language site AnTuTu reported that Samsung was running the Android 4.4.3 KitKat software on a mystery device with the model number "SM-G906A." The report implied that device model "SM-G906A" was the Samsung Galaxy s5. There is some validity to this claim as the specs listed for "SM-G906A" is exactly the same as the Samsung Galaxy s5. Though "SM-G906A" can be anything, it is more than likey that the device is in fact the Samsung Galaxy s5.

If true, this information indicates that Samsung may be scrapping the Android 4.4.2 KitKat rollout entirely -- in favor of rolling out the Android 4.4.3 KitKat Update on all its major mobile devices. Just two weeks ago, SamMobile released an internal Samsung document that seems to support this theory. The Galaxy s4 Mini, Galaxy Note 2, and Galaxy Note 3 Neo was amongst a lineup of devices that will be getting the Android 4.4.3 KitKat Update.  The validity of the document cannot be confirmed, even though it has a Samsung letterhead placed at the top.       

Information regarding the alleged Android 4.4.3 rollout date for Google's Nexus mobile devices originated from an Android Geeks report that was just posted two days ago on Saturday. The leak was purportedly based on anonymous insider information. Android Geeks also claimed that the Android 4.4.3 KitKat Update will soon be available for the Google Play Edition.

The long-awaited Android 4.4.3 KitKat Update is likely to be Google's last upgrade for the vaunted Android 4.4 KitKat software. So far, there has been much speculation that Google is working on the next Android 4.5 software, though no definitive confirmation from the tech giant has surfaced so far.
