How do I update my iPhone to iOS 16?
How to delete iOS storage to installed iOS
[Re-Titled by Moderator]
iOS is the operating system developed by Apple for its mobile devices like iPhones, iPads, and iPod Touches. Unlike third-party apps, iOS is a core system software, meaning it is an integral part of the device's functioning and cannot be deleted or uninstalled.
The only option available for users who wish to change the iOS experience is to upgrade to a newer version of iOS when one is released. Apple periodically releases updates to iOS that bring new features, bug fixes, performance improvements, and security patches. However, these updates can only be installed if they are available for the specific device model in question.
In case of issues with the current iOS version, Apple recommends troubleshooting or, in extreme cases, performing a factory reset to restore the device to its original settings. But overall, iOS itself cannot be removed from the device or replaced with another operating system like Android.
