After Huawei was the first to release a three fold phone globally this year, Apple's recent application for a four fold phone patent in the United States has been exposed, raising concerns about whether smartphones will further develop into more foldable forms. Senior industry analysts told First Financial reporters that they have not heard of Apple's development of a 40% discount phone, and Huawei's estimated sales of 30% discount phones this year are around 200000 units. The reporter learned from the patent data retrieval platform Zhizhiya that before Apple announced a new patent containing 40% off mobile phone technology, Chinese companies had already laid out 40% off mobile phone patents, but their patents are currently in the state of unpaid annual fees. From this perspective, both domestic and foreign companies are trying to seek breakthroughs in 40% off mobile phone technology, and industrialization is also influenced by market acceptance and cost control levels.
