Central processing unit of Mobile Phones: Mobile phones have central processing units (CPUs), similar to those in computers, but optimised to operate in low power environments. Mobile CPU performance depends not only on the clock rate (generally given in multiples of hertz) but also the memory hierarchy also greatly affects overall performance. Because of these problems, the performance of mobile phone CPUs is often more appropriately given by scores derived from various standardized tests to measure the real effective performance in commonly used applications. Display: Virtually all mobile phones have an integrated display device, some with touchscreen function. The main measurements for screen size varies greatly by model. Manufacturers use different methods to specify display size, usually width and height in pixels or the diagonal measured in inches. In 2011, a 3G Android Smartphone was launched with dual 3.5 inch screens. Furthermore, the screens can be combined into a single 4.7 inch which turns it into a Tablet computer. It uses a single Snapdragon processor.
