Research On Reliability Of Smart Phone Proximity Sensor

With the development of science and technology, mobile phone have been developed to smart phone. It is powerful with many kinds of sensors. With more and more sensors installed, the phone's reliability becomes a problem.This paper takes the proximity sensor's reliability issue as the object, and finishes the following topics with the reliability technology and tools:(1) Basic expound the development history and latest status of reliability technology, and deeply investigate the integration of the different reliability tools/methods and the development stages of mobile phones;(2) Basic expound the concept and major tools/methods of technology analysis?reliability experiment and reliability increase, and set up the common procedure to work on mobile phone development, and then start the analysis of the proximity sensor reliability issue, running experiment until the corrective solution finalized;(3) Find out the root cause of the proximity sensor reliability issue via experiment and implement the corrective actions to improve the system reliability, also make some comments on the next generation of the proximity sensor to prevent the same issue happening again.
