HTC sold the smart phone foundry business to Google so far. It has yet to demonstrate its momentum of revival. The revenue declined again 35.5% in February of 2018. The Acer mobile phone brand's recent performance in the global market is quieter. In 2017, Asustek, which started organizational restructuring in 2017, drastically reduced the manpower of its mobile phone business and reduced the number of open cases. With the next-generation ZenFone 5 listed on the market, it expects to return to profit in the third quarter, making Asustek a mobile phone brand of Taiwan. The main force that breaks down the plant in the international market is Asus. In the wake of the downturn in the PC market and delays in the launch of two generations of smart phones, profits have fallen into recession in recent years. In the face of the operational crisis, Asustek has launched an overall restructuring in mid-2017. The development of the mobile phone industry in the future will be a drastic and labor-intensive task. At the same time, we will adopt a strategy to reduce the number of cases. With the recent launch of the new generation of ZenFone 5, Asustek expects to return to profit in the third quarter, showing the benefits of mobile phone business restructuring. Supply chain manufacturers pointed out that Asustek’s new mobile phone team gradually grasped the rhythm of production and sales of mobile phones and clearly understood its position in the market. Firepower focused on NT$4,000. 50,000 yuan price to bring the market, the recent new ZenFone 5Q officially opened, with superior cost-effective advantages, shoulder the burden of shipment impulse, Asus will launch the second quarter, respectively equipped with Qualcomm (Sualdragon) Snapdragon 636 and 845 processor flagship models ZenFone 5/5Z. As Asustek has been able to meet the needs of the market from the start of the new machine to the fastest time, the R&D strength has not been lost to the mainland competitors. In particular, Asustek is listed in Qualcomm's next-generation Snapdragon 845 processor. The list of goods also showed a friendly relationship with Qualcomm. After the industry expects ASUS mobile phone to fully ship in the 10 major markets in the world in the third quarter, the mobile phone business should be able to achieve a return to profit in a single season. It is estimated that the shipping capacity of the entire year will be maintained. With 10 million sub-standards and stronger brand and marketing capabilities, it is expected to achieve profitability in 2019. By comparison, HTC, a Taiwan-based mobile phone brand factory, has seen a lot of recent performances, including success from the foundry. HTC, which has been transformed into a world-famous mobile phone brand, failed to hold onto the hard-won country. In 2017, it even handed out an elite mobile phone team and authorized intellectual property rights at a cost of US$1.1 billion. The rise and fall of the mobile phone industry has caused the industry to be overwhelmed. Honda’s 2017 consolidated revenue was only 62.12 billion yuan, which was more than 20% lower than 2016. The annual revenue performance was the lowest since 2004, and there is no improvement in 2018 so far. The revenue for February was down 44% year-on-year, which was the lowest since August 2004. The revenue for the first two months was 6.02 billion yuan, a 35.5% year-on-year decrease. Although HTC once again invited Mayday as the product spokesperson, the second quarter will also launch new machines, and Continuing to fight in the virtual reality (VR) market, but the industry is still not optimistic about its prospects, and even questioned that the development of HTC mobile phones has gradually become out of touch with the market, and it is expected that the VR business will probably follow the smart phone trail. Only recently came Google. The subject of earnings attention has attracted market attention. As for Acer, it has not been able to play on the mobile battlefield. The market continues to spread news that may be forced to abandon. Recently, Acer’s new strategy and follow-up outlook have not yet been seen. The mobile phone business is burning. Money, fearing to affect Acer’s overall profitability performance, coupled with Acer’s low brand recognition in the global mobile phone market, the future of the mobile phone business will be a big test for Acer. Supply chain manufacturers stated that In the face of HTC, Acer's mobile phone business in the global smart phone market has continued to decline. Asustek’s mobile phone business has become an important hope for Taiwanese mobile phone manufacturers to break through the global market. With Asustek’s comprehensive enhancement of mobile phone design and quality, it will be able to market in the brand. The combat power continues to intensify innovation, and has the opportunity to find another day in the mobile phone market in Southeast Asia and Europe and South America.
