Reverting a mobile operating system to a previous iteration involves uninstalling the current version and installing an older one. For example, should a user experience persistent issues after an update, they may choose to reinstall the prior stable version to regain functionality.
This process can be crucial for users encountering compatibility problems with newly released software, experiencing reduced device performance after an update, or preferring the interface or features of a prior operating system version. Historically, this was more common when updates introduced significant changes that users found disruptive.
