This area will not be cleared in the subsequent mobile phone software upgrade process, but the calibration parameters of the mobile phone will be lost due to improper operation by the operator during the upgrade. At this time, when the MMI reads the content of the fixed area, the area It still displays "Calibration Passed", which will misjudge the mobile phone whose calibration parameters have been erased as a qualified mobile phone, and it is not easy to guarantee the quality of the mobile phone

Embodiment
[0035] When the mobile phone is calibrated, some values in the nv (non-volatile, immutable) file will be changed. This embodiment also uses this as a basis and is applied in MMI (Man Machine Interface) software. When we downloaded the mobile phone software, the value of Battery[1] in the nv (non-volatile, immutable) file of the mobile phone was 0. After calibration, this value has been changed, and it must be a non-zero value. After that, when the phone is turned on again, it will first read the value of Battery[1] in nv (non-volatile, immutable) to determine whether it is equal to 0, if it is equal to 0, it is judged to be uncalibrated; if it is not equal to 0 , It is judged that it has been calibrated; then there is a difference in the display of the standby screen, the calibrated motherboard, there is no space between the displayed hour and minute; if there is no calibrated motherboard, the displayed hour and minute There are spaces between them. The operator in the funct...

The invention relates to a method for calibrating a mobile phone and the production flow control, in particular to a mobile phone and a method for judging whether the radio frequency calibration is performed correctly. The mobile phone comprises a control unit, a memory cell, a judgment module and a display unit. The method comprises the following steps that: A. the control unit controls mobile phone software to be downloaded to the memory cell, a value of a calibration variable in the memory cell is changed to be a default; B. after the mobile phone is calibrated by the control unit, the value of the calibration variable in the memory cell is changed to be another different default; C. when the mobile phone is switched on, the value of the calibration variable is read from the memory cell by the control unit; D. the judgment module judges whether the value of the calibration variable is the default, if yes, the calibration is not performed and the display unit displays an interface representing that the calibration is not performed; if no, the calibration is performed and the display unit displays the interface representing that the calibration is performed. The method judges whether the calibration is performed according to practical calibration data intuitively without mistakes.
Description
Technical field [0001] The invention relates to a mobile phone calibration method and production line flow control, in particular to a mobile phone and method capable of correctly judging whether it has undergone radio frequency calibration. Background technique [0002] After the mobile phone patch is finished, it must go through the stations such as downloading, writing SN (SerialNumber) number, calibration final test and function test. Among them, the final calibration test station is extremely important, which directly affects the radio frequency performance of the mobile phone. The flow of calibrated mobile phones to the market will affect the normal use of users, and also affect the battery life of the mobile phones, so the calibration station must be strictly controlled and not missed. [0003] Currently, in the mobile phone chip solution, the method to determine whether the mobile phone has undergone radio frequency calibration is to write the content of "calibration passed...
