I've seen lots of reviews and sites talking about all sorts of features of phones, but rarely (if ever) is there much discussion about bluetooth 4.0 vs 4.1.
A quick search on google shows what the main differences are, and they look rather significant to me, though I'm obviously not an expert. Some of the newer phones (like the note 4) ship with bluetooth 4.1 support, while most others ship with 4.0 support. Is that something that is software/firmware updateable , or is a device with 4.0 support going to be permanently limited to bluetooth 4.0 support?
