Update 2
I have disabled my dev pre app and tried to update my phone again guess what it went through and got denim in extra+info...! I went curiously checking phones new features all the above discussions..!best part NOTHING CHANGED
EXCEPT FIRMWARE AND OS VERSION...!
To confirm I opened store downloaded Lumia camera which says 4k stuff...!
After the installation when I open it...says Lumia camera need denim update...!lol
That's what I was on...!
Some bloody online article said...to get denim working u need to start from the scratch
It means downgrade to 8 or 8.1 cyan the first rollout and update....!
