No doubt samsung is a no.1 company in india.How could company like samsung miss on this, I wonder wheather they checked it or not.the phone sound while talking is below average, to be frank its poor.while in traffic, just forget about it.you should look for by lanes to pick up the call.even sound is not well audible despite volume levels are full.please rectify this.don’t you think this is a main feature customer look for while buying , please excuse.you can buy this phone if you are ready to compromise with its sound quality , other feature are good but not best.
