The mobile OS world market leaders are Android and iOS with shares of respectively 37.2% and 27.2%. The fight between the two is hot, iOS having lost much of its past advantage and growing at a slow pace, while Android keeps running upward, at a monthly rate of 3.9% in the last 12 months. Samsung is stalling, and Blackberry's happy days seem definitely over. Nokia's Symbian, on a steep downward fall, reveals the loss of confidence in Nokia, whose strategy is a cause for wonder. However, another Nokia product — Series 40 or S40 — has been highly successful in recent months, growing from nil to a 13% market share.
