Firstly when I saw an advertisement of the Lumia Smartphone I got very excited and I thought that I will definitely buy it. But Believe me these phones are just crap and wastage of money .
I have used Android as well as iOS , and this Lumia comes in no match with them. So never ever Buy it. It's OS is crap , It's camera is ok, itd battery backup is also okay. And other features works just fine. But I didn't experienced any fun which we usually expect while using any phone for the first time . So I Am disappointed . SORRY NOKIA!
