The Samsung`s Finland site is showing a list of mobiles that will be upgraded to Android 5.0 Lollipop.
On the Charts we have posted below are included the Galaxy Alpha, Galaxy S4, Galaxy Mini S5, Galaxy Note 2, Galaxy Note 3 and Galaxy Note 4.
The Galaxy S5 is not included on the list. Unless the list is not updated we think the Galaxy S5 is a must have upgrade since it was launched this year 2014.
There is no information about the upgrades to Lollipop for the Samsung tablets as you can note on the site.
