Oh I searched the forum but still you can see that many Indians who updates their Lumia 720 with Amber didn't get Nokia Smart Cam.
First Read this thread, then reply.
What I think he means is IT will work on any Lumia with Amber you just might have to do some tricks
to download to your phone.
Read this:
You can use this convoluted method ( not just for Pro Cam)

or you can download this app for $1.29 which does work BTW

or you can download SysApp Pusher

then look for the Nokia photo apps and find Smart Cam or Pro Cam etc. and then go to your Wi-Fi setting and change to PROXY
Server/URL 117.135.139.179
PORT 8888
Be sure click the check mark then go back to that app and hold the back button for about 3 seconds then release it and hopefully it goes from (!)
This app not available for your device...to INSTALL
You may have to do this "trick" several times to get it to change to INSTALL but if and when it does click INSTALL and
it will stall & "attention required tap here" will appear but
don't do anything but go back to Wi-Fi and enable the WiFi to your normal settings and then the "attention required tap here" will be gone and it will be installing. You may have to try this several times is if keeps stalling but it will download eventually.
