Samsung,The mobile giant, unlike it's competitor- Apple Inc, made the awful mistake of allowing itself to be absorbed too much in the android operating system. Of course android market is going at a fast pace and android is pretty user friendly but almost everyone is making a mobile device that uses android. The outcome? Samsung had it's devices imitated over and over again to an extended that some of the imitations are better than the original Samsung Brand.
Samsung will definitely lose it's market in the long run. Apple was clever enough to make their devices run on their unique software- IOS. No one will ever imitate an iphone and succeed as much as how smartphone manufacturers imitate Samsung devices to a terribly accurate extend.
