an easy way to improve hadware and software on mobile phone

Mobile is one means of communication. We have very rapid development of mobile phones almost every month is always out of new models from each brand mobile phones, mobile phones and even this seems to be a staple of everyone. But on the other hand too much damage to the phone, and on the other hand is also a lack of mobile field technicians.
In this final task, the author will try to explain how the most simple and small in the follow-up software and hardware damage to the phone, so the damage was not severe but can be resolved.
The final results are expected from damage repair software and hardware on this phone is that every person who has a mobile phone capable of handphonenya first aid in case of damage to themselves, such as wet, hang, phone mute, and so forth.
Because for a doctor, if you already know the disease and its cause, it's easy to stay sought a suitable drug alone. So let's say, by reading this information we learn to become doctors phone. At least for the mobile phone itself.

CHAPTER I
INTRODUCTION
1.1 Background
In line with modern technological developments in such a rapidly growing, which has been in use various electronic devices to meet the needs of society as demands of the times, almost any time and wherever we Barada always dealing with things that smell of electronics.
In the world of work, skills can be utilized electronics is because the problem is closely related electronics and support to other areas such as medical, transportation, military, and many more. Therefore, by mastering the science of electronic means can be engaged in any field, including the thing is currently developing a community among the communication devices.
Communication is basically the exchange of information between one another. The information referred to here is the voice signal or a conversation.
With advances in technology, better communication skills developed to meet the needs of, among others is a mobile phone.
Work on the phone system itself is a combination of interrelated elements that combined integrate to achieve an overall target. mobile phone is an electronic device that has some components that are strung together in some integrated circuits on a system.
Basically the phone is divided into three (3) system are:
1. System basband (local phone bottom).
In this system there are several functions including:
a. Power Distribution
Serves to make the spread, distribution, and regulation of power (voltage) to several components. This became the task of IC Power pentingdari contained in Basband.
b. Power UP and Down
When on-off switch is activated, then it will activate the signal to the IC and IC CPUs that are in Power basband.
c. Audio Control
A section in charge of controlling functions - audio functions, mic and speakers such as external and internal.
d. Memory
Part of the basband store data - data that the program consists of MCU, PPM, and EEPROM.
