"This is still a market segment led by Samsung, but the trend is unmistakably toward larger-screen handsets at the high end of the market. It held a 44% share of devices with displays of 5" and above, and 53% if the view is narrowed to look at 5.5"-plus displays," said Canalys Analyst Jessica Kwee. "But many other vendors, such as Lenovo, Huawei, LG and Sony, have also achieved significant volumes in this space with products at the top end of their portfolios. Consumers now expect high-end devices to have large displays, and Apple’s absence in this market will clearly not last long. It is notable that 5" and above displays featured on almost half (47%) of smart phones with an unlocked retail price of US$500 or more. Of the remaining 53% of high-end smart phones, 87% were iPhones. Apple plainly needs a larger-screen smart phone to remain competitive, and it will look to address this in the coming months."
Apple is expected to release a 4.7-inch iPhone 6 as soon as August and follow that up with a 5.5-inch iPhone 6 as early as September.
