SEOUL: The latest version of Samsung’s flagship Galaxy smartphone went on sale worldwide Friday, days after the electronics giant announced it was facing a second consecutive quarter of profit decline.

The Galaxy S5 has a lot riding on it to steer the South Korean firm’s profit-making machine back on track as growth in smartphone sales slows, with mature markets like North America and Europe near saturation.

Reviews of the S5 have mostly concluded that it is one of the best high-end smartphones on the market, but there is also a general consensus that it lacks the “wow” factor needed to differentiate it from its predecessors and competitors.

“It can swim, but it won’t make any waves,” was the verdict of the Wall Street Journal, referring to one innovation in the S5’s waterproof covering.

“The Galaxy S5 is a good phone. It earns an unreserved recommendation,” said the Washington Post.

“But the truth of the matter is that there’s really nothing here that’s worth breaking your contract to buy,” it added.

Samsung’s mobile unit has been the driving force behind the record profits of recent years, and it needs the S5 to perform well as a retort to doom-mongers who say the company lacks a clear strategy to flourish in an increasingly competitive, saturated market.
