Samsung Galaxy S4 would come with another feather in its cap, this time it is a health pad accessory. Akin to the one which was about to come in Samsung Galaxy S3, this app would let you measure your blood pressure, glucose levels, BMI, pulse rate and so on. If Samsung is able to pull this feat, than Samsung Galaxy S4 with S-pen and S- health would be lethal competition to beat by Apple iPhone 5S.
