Nokia was once the dominant mobile phone manufacturer, holding over 30% of the global market share. However, its market share dropped below 30% in 2011 as it struggled to compete with smartphones running Android and iOS that had more advanced apps and processors. In an attempt to turn things around, in 2011 Nokia partnered with Microsoft to use the Windows Phone platform for future devices. However, Nokia remained dependent on Microsoft and faced strong competition from Apple and Google, making a full recovery difficult. The partnership aimed to combine Nokia's manufacturing and distribution with Microsoft's software expertise to build a new mobile ecosystem.
