Accordign to the UK carrier Three Samsung’s Galaxy S4 mini won’t receive the Android Lollipop update. The revelation was made by the carrier in response to a user’s question on Twitter.
It seems that the memory limitation of the S4 mini it’s the reason for that. The Three also revealed they’ve received an official confirmation for the same from Samsung.
However it seems that Ireland’s branch of Three will indeed release a Lollipop update for the Galaxy S4 mini. In fact, it has already started rolling out, so it’s apparently a region/carrier dependent update. At least this was a tip from a GSMarena reader.
