Mobile phone repair, including inspection failure, determine the scope of failure and the use of tools for maintenance of the
two processes.

Two. To see. Get the phone, the observation of mobile phone casing is intact, the screen display is normal, whether the signal strength value, whether there is network, handset and transmitter is normal, whether the water and other aspects of the situation, combined with past experience in order to further to judge the failure to provide ideas.
3. Listen. From the phone's voice quality, volume of noise phenomena such as preliminary to determine the fault coverage.
4. Touched. Power through a larger standby current phone, the back of the hand to touch the components of the surface temperature of the hot component is generally damaged, alternative method to be eliminated.
5 Thinking. According to previous observations, the data collected and previously learned knowledge and experience accumulated use, complemented by a number of measured parameters to identify the scope of the failure of proposed method of repair.
