I had a bad luck of buying this phone. Well worked fine exactly for a year and then Mother board went dead. got it replaced paying 1/3rd of the price of the phone. and was working fine for 5 months and then again went bad.
And they are again asking for same amount to change the mother board. so I would say worst product ever to buy.
Later, they called me up and did a follow up with the service centre and got my problem solved by replacing the M/B for free for a out of warranty mobile. And I am really happy with the resolution.
