As the first work of the Android platform launched by Google in collaboration with many industry giants, HTC G1 adopts a shape very similar to that of T-Mobile's customized SideKick phone in terms of mobile phone appearance design. It not only has a large touch screen, but also features a unique side slide cover design. With the help of a standard QWERTY keyboard, users can obtain more convenient and faster usage experience when browsing the Internet and entering text. Moreover, in order to obtain a better Internet experience, HTC G1 will be equipped with a 3.17-inch high-resolution 260,000-color LCD screen with touch function. After the user enters the main menu, they can achieve different interfaces/functions by moving up, down, left, or right with their fingers. For example, moving from the top of the screen downward pulls out a reminder interface, which can check the day's schedule reminders, unread messages, missed calls and other reminder functions. Moving this interface from bottom to top can slowly retract this reminder interface.
