The innovation of smartphone is never ending and will continue to evolve over the time. 5 years ago when people talked about smartphone, touch interface was new to many end users and it was just about to take off displacing QWERTY keyboard. Today, nobody care about touch UI because it is nearly impossible to find a smartphone without touch interface. What we see today is voice driven input interface and gesture recognition applications are being adopted by more and more people, thanks to higher processor performance, higher cellular data rate, and better voice recognition algorithms. All of those technological breakthroughs make it possible to carry out complicated data acquisition and analysis and on the device or in the cloud. Few years ago when the mobile display is less than HD (high-resolution), people can only do simple UI operation or chat online with text messages. Today, as HD or Full HD display has become the basic smartphone specification, HD content streaming or messaging with text, images, voice, and videos are things people do when they take bus to work. Today, as more and more high-end mobile devices are equipped with 4K display or retina display, we can expect to see UHD (ultra-HD) content streaming or broadcasting over cellular networks from studios. The apps, which is really one of the enzymes to ignite the smartphone revolution, will evolve from gimmicky branded apps and games, to a unique personalized mobile services leveraging location, context, usage behavior, and data. The buzz word of contexture awareness, console gaming on mobile devices, mobile payment, are within the reach.

The redefined premium user experience is not possible without the technological breakthrough. The heart of the smartphone innovation includes the CPU, GPU, modem and connectivity, video codec, peripherals, etc., just to name a few. Over the past 5 years, it is observed that the CPU performance has enhanced 36x, while the GPU performance improvement is 40-folds and video codec complexity has increased by 34 times. With the LTE deployment and new techniques in Wi-Fi, the cellular and connectivity data rate has increased by 40 times. The demand of memory bandwidth and capacity has also increased by 16 times.
