How could company samsung miss on this, i wonder whether they checked it or not.The phone while talking is below average, to be very frank its poor while in traffic, just forget about it.you should look for by lanes to pick up the call.Even the sound is not well audible despite volume level are full.Please rectify this.Don’t you think this is a main feature customers look for buying. Its screen is very thin and samsung has not put good quality material to protect this screen from a normal fall.
