First of all, society is developing in the direction of high technology, intelligence and rapidity at a rapid speed. Nokia mobile phone is the representative of the old mobile phone, and its new products can no longer meet the public's requirements for information and intelligence.
Second, the "Symbian system" of Nokia's mobile phone itself has been replaced by smarter systems such as Android and Apple, and Nokia's mobile phone has not been updated in time, resulting in its share in the mobile phone market gradually declining;
Third, the cooperation between Nokia Group and other companies failed, which missed the opportunity to enter the smart phone market. So when a large number of smartphone brands appeared, Nokia was already at a disadvantage and could not be reversed;
Fourth, consumers' pursuit of new products, as everyone expected, has prepared funds to snap up the newly listed Apple mobile phone. The public has been familiar with Nokia's functions, and the demand for new functions of mobile phones is also rising, so Nokia mobile phones can't be sold.
Although Nokia failed to achieve good results in today's smart phone market, before the development of smart phones, Nokia occupied the vast majority of market share. At this time, Nokia is also developing new products, such as: King of Photography 1020, the first flagship of WP8 and so on. As soon as it was launched, it had a wide impact.
Nokia has not been eliminated today. Nokia is still smart today. It introduced a new Android smart phone, which uses a full-screen hole-digging screen with three cameras to five cameras, and supports updating to Android 10 operating system.
Your question about Nokia may be why Nokia's once popular push-button mobile phone has been eliminated. This is because the times are progressing, and the touch-tone mobile phones will definitely be eliminated. Not only Nokia, but any brand of mobile phones that want to gain a foothold in the new era will launch devices that conform to the characteristics of the times and will eliminate touch-tone mobile phones.
Nokia's market share is getting lower and lower, which is related to the rise of smart phone brands in Chinese mainland. Domestic mobile phones are more and more in line with the habits of Chinese people, and Nokia has gradually withdrawn from the mainstream level and become the heart of young geeks with love.
The cooperation between Nokia and Microsoft is also the reason for Nokia's decline. The cooperation between Nokia and Microsoft is Microsoft's malicious competition. Microsoft used to take Nokia as its own through some seemingly legal but completely unfair competitive means. In the trend of the times, Nokia was forced to go against the trend and not produce Android phones with Nokia. In the end, Microsoft sold Nokia again, which made Nokia suffer a serious blow.
Today's Nokia is making a comeback. Nokia, which parted ways with Microsoft again, is one of the three largest suppliers of 5g base station equipment in the world (Huawei, Nokia and Samsung). Nokia's mobile phones are also profitable. Although it is no longer popular in China, it still has a very important position in the world.
