I am complaining about bad quality camera. The phone camera specification is 17 mb, but while snapping photo, we looks like a ghost, full black shaded, bullar, unclear image. When i complain about the same in amazon within 10 days of replacement offer, theytold it is impossible to replace. They are cheatingcustomers with invalid offers. Regarding the network coverage, it is very poor intermittent coverage
