First, run the synchronization assistant, and connect the device to the icon of more function tools. Second, enter the operator version in the pop-up interface to enter the general settings of the device. You can check the version of the application provider about this machine. Third, you can modify the text or icon of the modifiable operator. After I confirm, click Settings. My assistant suggested that after the setting is successful, please go to the mobile phone settings and turn off the custom text of flight mode. If the modified content is not displayed on the phone, please try to close the background application and restart the phone.
