Apple mobile phone settings do not automatically update the system steps:
1, Apple devices will automatically download the update files under the default networking conditions, mainly because there is no relevant program option to close the system automatic update application. Therefore, it will lead to the automatic download and update of system files when networking, so that the update prompt will be displayed on the screen settings.
2. If you want to cancel the system prompt for updating device settings, you need to completely delete the automatically downloaded system update file. However, if you directly enter Settings-General-Software Update, you cannot directly delete the downloaded updated system files.
3. Downloaded update files can only be completely removed by erasing the system contents. Go to Settings-General-Restore-Delete all contents and settings.
4. Of course, choosing to erase all the contents and settings is equivalent to restoring the mobile phone to the original system, so back up all the important files before restoring the settings. In this way, after the device is restored, important information can be restored to the device.
5. When the system erases all contents and settings, you need to enter a password. Changing the password may be different from your screen saver password and independent; It doesn't matter if you don't remember After three mistakes, you will be prompted to change your password. So don't worry about remembering the password at all.
6. After the system erases all the contents, look at the icon that the mobile phone no longer prompts to update the system. Of course, there is no downloaded system update file at this time. So the next step is to turn off the background automatic download update function.
7. The operation methods of completely prohibiting the system from automatically downloading updated files are: set ——itunes Store and AppStore. After entering, in the automatically downloaded project, the functions of application and update are turned off, and the underlying cellular mobile data is also turned off, so that the system will not automatically download the updated program under any circumstances.
Of course, this also has a disadvantage, that is, other software of the mobile phone will not be automatically updated. If you need to update the installed software to the latest version, you need to enter the AppStore to manually update and upgrade the software.
