The company was once No. 1 in the smartphone market, but has since dropped out of the top five.”The biggest difficulty for us at present is on mobile phones. We know that [to produce] phones with small size and low power consumption requires advanced technology. Huawei can do the design, but no one is able to help us to produce. We are stuck,” Huawei Chairman Guo Ping said in a Q&A with staff, according to a transcript seen by CNBC.One of Huawei’s biggest issues is that Chinese chipmakers do not have the ability to make the cutting-edge semiconductors that the Shenzhen-headquartered company requires.Guo said, however, Huawei will not exit the smartphone business. Instead, it will work with partners in order to improve their technology which will in turn benefit Huawei as it could get access to China-produced silicon.”Huawei will keep its existence in mobile phone sector,” Guo said. “I expect that as the capability in chip manufacturing increases, [Huawei] will return to the smartphone throne.””I hope the day when China is able to make chips can come sooner. Until that day, the sector will exist, and we will try to retain and develop our technologies, to make sure we are able to make competitive phones,” Guo added.Last year, Huawei sold off its budget smartphone brand called Honor, in a bid to keep the business alive.Huawei has shifted its focus to areas such as software and cloud computing as the smartphone business continues to face headwinds.
