Which means, Cortana Alpha should be there on both the devices for supported countries like India, Canada and Australia. Yes, it is present there in the app list, but you need to make a small change in speech settings before you can use it. You need to set the speech language as “English UK” for India and Australia and “English US” for Canada and you should be able to use it, as can be seen in the above screenshot.
While, Cortana is present, there is something which is a surprise miss! Lumia 830 and Lumia 730 still have Nokia Camera in place of Lumia Camera, which was supposed to come with Lumia Denim update and brings features like Moment capture, Rich capture, better imaging algorithms. Read all about Lumia Denim here and read all about Lumia Camera here.
We reached to Juha, the Imaging expert at Microsoft mobile with our query and he says that Lumia Camera will come later this year. This is one more classic case of building up the excitement and then making users wait!!
