The operating system iteration on Apple’s mobile devices is a critical software component. Identifying the specific OS build running on an iPhone or iPad, for example, allows a user to determine compatibility with apps and features. Finding this information is typically achieved through the device’s settings menu, under the “About” section.
Knowledge of the operating system release is essential for several reasons. It dictates access to the newest functionalities and security patches. Older versions may lack enhancements present in more recent releases, potentially leaving devices vulnerable. Historically, each subsequent release has aimed to improve performance, security, and user experience.
