Microsoft, the American software giant, acquired Nokia mobile business for $ 7.2 billion in 2014. However, it failed to make achievements with the new device. The Windows OS based on WP only accounted for 1% of global smartphone sales in May.

Some experts analyzed its failure is due to Microsoft did not step into smartphone industry in time. It lost a head start.

Eddie Murphy, analyst of Priory Consulting, said Microsoft spent a lot of money to launch WP as it realized the importance of smartphone industry. The question is that Microsoft lost a head start as it step into this field late. Apple and Android devices have already controled the market when it released WP devices.

One of the difficulties that Microsoft encountered is app gap. It was unable to offer the popular apps which are available on smartphones. It happened to Blackberry BB10 as well.

“The app gap is a big problem,” said Murphy. He also has a Windows mobile whose apps are fewer than Android devices. It is disadvantage to Microsoft.

The staff reduction plan it announced on Monday is a part of plan that it made to cut 1,850 jobs for Microsoft mobile department in May.

Microsoft latest Windows 10 is compatible with samrtphone. In February, HP enterprise announced to turn a smartphone based on Windows 10 to a desktop.

Murphy said Microsoft must have been learning what Google use Android OS for? The reason why Android OS could be in such a dominant position is that Android OS is open. Microsoft have released the general Windows 10 OS for desktop, iPad and mobile. It is a good sign as it would bring some more apps on this platform.
