									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.


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.
