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 being calibrated, it will change some values in the nv (non-volatile, immutable) file. This embodiment is also based on this, and is applied in the MMI (Man Machine Interface, man-machine interface) software. When we download the mobile phone software, the value of Battery[1] in the nv (non-volatile, immutable) file downloaded to the mobile phone is 0. After calibration, this value has been changed, and it must be a value other than 0. After that, when the mobile 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 will be judged that it is not calibrated; 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, there is no space between the displayed hour and minute on the calibrated mainboard; if there is no calibrated mainboard, there is no space between the...

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 process control, in particular to a mobile phone and a method that can correctly judge whether it has been calibrated by radio frequency. Background technique [0002] After the mobile phone patch is completed, it needs to go through the stations of downloading, writing SN (Serial Number, serial number), calibration final test and function test. Among them, the calibration final test station is extremely important, which directly affects the radio frequency performance of the mobile phone. If The flow of uncalibrated mobile phones to the market will affect the normal use of users, and also affect the battery life of the mobile phone, so it is necessary to strictly control the calibration station and not miss it. [0003] At present, in the mobile phone chip solution, the method of judging whether the mobile phone has undergone radio frequency calibration is to write the cont...
