Samsung says that the S6 curved screen is tough to make. The new flagship mobile phones go on sale today but Samsung says that the S6 curved screen has a high demand and is difficult to keep up with.

Though Samsung forecasts better interest in its more unoriginally designed S6 model, it is worried about the time it takes to manufacturer constituents for the characteristic wrap-around touch screen on the S6 Edge.

Many experts believe that this will delay the fall in price as it could lead customers having to order and then wait.

The top end mobile market is a home for companies like Apple and Samsung faces severe competition from Apple but on the other end of the spectrum, Samsung also faces China who are able to make replicas at a fraction of the cost.

Mobile analyst, Thomas Husson at Forrester told the BBC that Samsung is in trouble because this shortage will hurt their market and if this is a manufacturing problem than Samsung is in real trouble.

If Samsung is to regain their leadership in the high end mobile phone segment that they will need to successfully launch these flagship phones. If the iPhone comes out, the customers who are willing to buy the S6, will go for the iPhone.
