Another method of calibration involves the engineering menu, a special program hidden by developers from the eyes of ordinary users. It is usually used for the purpose of testing the operating system and setting any parameters of the device. You should be very careful when touching the menus because incorrect changes in the settings can cause the gadget to behave improperly and can cause, for example package parsing error. To enter the technical menu on your phone, you can use USSD-command.
