I will clearly brief my review in few points:
Too large screen phone. Not too compatible.
When works, it works very fine.
Windows phone 8.1 totally outdated OS.
Lots of problems with screen display.
Nokia Customer service:
If in warranty, they will repair it free of cost.
Out of warranty, they charges 8k for display.
Nokia care not so CARING.
My Suggestions:
Do not buy this phone in 2016 era.
If brought, take a lot care of the screen. Do not put pressure on screen.
