The Nokia smart cam is available on the 520 (I installed it) in India but not on the 720 both of which I have updated to Amber. I will the customer care and update the post with what response I get.
Even I updated my 720 with Amber update but could not find the smart cam app on the store. If tried it through app social then I got the same screen as posted. I will try on my 520 and reply.
