The following result is obtained by our expert's opinion:
Samsung and Apple both serve a different purpose in the smartphone industry. It looks they are competing but actually they are working they are complementing each other. With the aim to create a duopoly in the premium smartphone business. Users of both smartphones have different needs. Both companies compete to convert users of each other.
Features of iPhone are simple but work perfectly with a very fine performance.
While features of Galaxy S or Note series are very unique and great and serves multiple purposes.
