As seen in the purported leaked roadmap, the KTU84P update (Android 4.4.4) for 2014 flagship Galaxy S5 (SM-G900I and SM-G900F) along with Galaxy Note 3 (SM-N900) and Galaxy Note 3 LTE (SM-N9005) is listed as complete. Further, the roadmap notes the ETA (estimated time of arrival) of the update for these phones as October.
The leaked roadmap also claims that the Android 4.4.4 KitKat update for the Galaxy S4, Galaxy S4 LTE, and the Samsung Galaxy Note 3 Neo smartphones is in final testing with a roll-out scheduled for November.
Meanwhile, other phones including Samsung Galaxy S4 Mini, Galaxy S4 Mini Duos, Galaxy Grand 2, Galaxy Grand 2 Duos, Galaxy Note II, and Galaxy Note 2 LTE are listed as pending, which means work on the Android 4.4.4 KitKat update is still happening. However, the purported listing notes an expected roll-out time of November for these phones.
Recently a report had suggested that Samsung's 2014 flagship, the Galaxy S5, along with the Galaxy Note 4, might receive the Android L update in late-November or early-December. A video claiming to show a Samsung Galaxy S5 running an Android L test build (LRW58J) with the company's new TouchWiz UI surfaced online earlier this month.
