STUDENT 1 : Mobile devices have come a long way, building on their traditional phone function to become general-purpose communication consoles. In 2020, they’ll get better, faster, stronger yet.2019 was a year of triumphs and challenges for the smartphone industry. The world has now entered an era of cell phones with superior functions. Over the past 20 years, the following aspects of mobile devices have undergone significant changes   STUDENT 2 : :Style and appearance. One of the most observable changes is the look and feel of mobile phones. They have changed from their original candy-bar form to the iconic flip phone, which enjoyed great popularity for a long time. Then the slide phone took its place, thanks to its modern design and convenient operation. Next was the touchscreen phone, the most widely available style in the current smartphone market.      STUDENT 3  : Size. Like computers, when mobile phones first came out, they were big and bulky; today they’re small and lightweight. The goal throughout their evolution was to meet the needs and expectations of users—to be more portable and user-friendly. STUDENT 4 : Function. Of course, mobile phones, starting way back with telephones, were invented for communication. In the past, phones played a single role: they allowed people to make calls. Thanks to the development of networks, technology, and social needs, phones today let users do much more—send and receive text messages and emails, take photos and videos, access the internet, listen to music, and play games, among many other functions. That’s not to mention artificial intelligence (AI) technology. STUDENT 5 Image/camera technology. The photography function is one of the most remarkable changes in modern smartphones. In the beginning, most smartphones had a single camera for photo shooting. Then the smartphone camera came of age: it moved to the screen display, facing the user, then adding video, high-definition, night-mode, and anti-shake technology. All these features together make the photography function the most valuable addition to the modern smartphone. STUDENT 6 : More screen. Most smartphone companies have introduced phones with full screens. There’s no denying that full screens have advantages—they give the smartphone an outstanding screen display and stunning visual effects. The full-screen design, to some extent, drives creative development in the smartphone industry.   STUDENT 7 : Artificial intelligence. AI technology will significantly enhance the user experience, improving smartphones’ sensing, analyzing, and interacting functionality. For example, with on-device sensors such as Wi-Fi, Bluetooth, and Global Positioning System technology, a smartphone can create a rich, offline profile of its user and even foresee his or her needs, then make suggestions that will help fulfill them. And through machine-human interaction, the smartphone can collect feedback, continually correcting mistakes so that it’s in lockstep with the user
