Users of multiple Samsung smartphones can check their devices regularly for Google's Android Lollipop OS update, as there are hints of an imminent rollout.
Samsung's engineers are also said to be working on releasing Android 5.1 to users of the comparatively older Galaxy Grand Prime, in due course.
The same report also states that, apart from the above smartphones, users of older handsets such as the Galaxy A series will also be seeded the Lollipop update, albeit the older version (Android 5.0, not Android 5.1).
The exact list of old Samsung smartphones eligible to receive Android 5.0 (Lollipop) is yet to surface at this point in time. However, it has emerged that the South Korean technology giant is reportedly yet to begin development of the Android Lollipop for release on Galaxy Note 2 smartphones across the world.
As of now, multiple carrier-driven Samsung Galaxy smartphones across the US are being seeded the Android Lollipop OS update, and wireless carriers in the US have resorted to competing with one another to release the Android Lollipop for their respective users.
Therefore, users of carrier-unlocked Samsung Galaxy smartphones are advised to check their handsets for newer OTA notifications that could very well represent the Android Lollipop OS update.
