I bought Microsoft Lumia 535 in December 2014 from amazon.in . It was lauched by nokia as "5 ka dum" as 5inch screen, 5 miga pixel front camera and 5 miga pixel back camera. That time is was value for money phone.
My main purpose to bought this phone was its battery backup. I love nokia because of their battery back only. It came with windows 8.1 operating system but they updated my OS time to time and now they provide me windows 10 free of cost.
so you can go for it if you need 3-4years life span phone in under 10000 rs.
Best wishes from my side.
