The process of reverting a mobile operating system to a previous iteration, specifically moving from version 18.1 to version 18, is generally undertaken to address compatibility issues, performance deficiencies, or user preference for the earlier system features. For instance, a user experiencing reduced battery life or software bugs after updating might choose to revert to the more stable previous version.
The significance of this action lies in its potential to restore device functionality or user experience that may have been compromised by a software update. Historically, users have resorted to such procedures when official updates introduce unforeseen problems or remove features they value. The ability to revert provides a safeguard against potentially detrimental software changes.
