The Samsung Galaxy Note 2, the Samsung Galaxy S5 Mini and the Samsung Galaxy Alpha are smartphones that from the outset were already strong candidates to upgrade to Lollipop, as it was even confirmed on occasion. But, in case there were still any doubts about it, the official website of Samsung in Denmark has dawned with an update in which it is reported that the next update that the Samsung Galaxy Note 2, the S5 Mini and the Alpha will receive will be the Android 5.0.1 Lollipop.
This web page ( www.samsung.com/dk/info/update.html#mobile ) does not refer to any specific date for the distribution of the Android 5.0.1 Lollipop update between these three mobiles. Even so, being a completely official page, we cannot rule out the possibility that the arrival of this update could be much closer than what was initially thought. After all, Samsung's high-end smartphones have already started to upgrade to Lollipop in some parts of the world.
The fact that the update mentioned for the Samsung Galaxy Note 2, Galaxy S5 Mini and Galaxy Alpha is Android 5.0.1 Lollipop should come as a relief to the owners of some of these smartphones. We are talking about a version that incorporates some bug fixes compared to the first Lollipop distributions, which translates into a more stable update that should not cause major problems for the owners of these mobiles.
In any case, whatever the source may inquire, in these there is no official confirmation regarding the dates for the distribution of Lollipop update on each smartphone Samsung within moments of each country. The only thing that exists at the moment is a list of smartphones that are confirmed to be updated to Lollipop, and this list consists of the following mobiles: Samsung Galaxy Note 2, Samsung Galaxy S4, Samsung Galaxy Note 3, Samsung Galaxy S5 Mini, Samsung Galaxy S5, Samsung Galaxy Note 4 (also including Note Edge), Samsung Galaxy Alpha (probably including the Galaxy A3 and Galaxy A5 as well).
On the other hand, the update to Android 5.1 Lollipop from Samsung seems to be waiting much longer than originally planned. Rumor has it that this update will bring new features to the TouchWiz interface which will include, for example, fewer factory-installed applications. And let's not forget the Android 5.1 news that the US company Google itself announced when announcing this update.
Regarding Android 5.1 there is no confirmation whatsoever from Samsung, so in this case it is completely impossible to talk about specific smartphone models planned to be updated to this version (beyond the flagships, see the recently presented Samsung Galaxy S6 and Samsung Galaxy S6 Edge).
