I am using since Feb-2016. sound and quality of voice calls is not that good. micormax spark that I had earlier was far better. Touch screen is in repair now. I have asked for replacement . they are still investigating and will can do it if company decides so or will keep trying it for repair. this may extend for 30days too. thumbs down. models lesser that this price range work better.Second thing is camera this camera is lacking somehow. And my main purpose was good camera. Not happy for that.
