Numerous problems have plagued Apple's latest operating system for its mobile devices, the iOS 8, ever since its release. The company has received complaints for every aspect of the operating system, such as WiFi difficulties, sluggish performance, decreased battery life, audio problems and iTunes syncing issues.

The latest complaint against iOS 8 is not just in the form of a user venting out on support forums, as two customers of Apple from Miami, Florida filed a class action lawsuit in the U.S. District Court in San Jose.

The lawsuit accuses Apple of "unfair, unlawful, and fraudulent business acts or practices," along with the deception of the public, in relation to how much space iOS 8 takes up in the memory of devices, which is as much as an additional space of 600 MB to 1.3 GB.

The plaintiffs of the lawsuit, Christopher Endara and Paul Orshan, are upset that the latest iOS can consume up to 23 percent of the storage capacity of devices. The lawsuit, which seeks damages of over $5 million, is filed for all consumers that bought an iPod, iPad or iPhone with storage capacities of 16GB or less with iOS 8 pre-installed, or those that upgraded to iOS 8 from earlier versions.

The plaintiffs state that Apple proposes that users, amid the shrinking storage space on their devices, should purchase additional storage space on iCloud. The lawsuit states that the company is giving lower storage capacities than they advertise, then offer paid storage capacities in desperate moments for users, such as when the user is taking pictures or recording videos of important events.

The lawsuit also targets that fact that users that have upgraded to iOS 8 are not allowed to go back to previous version of the operating system, which is a common complaint for the users that are experiencing the reported bugs of the latest iOS.

However, the lawsuit is shaky on the assertion that Apple does not allow its users to access storage capacities of other companies, as there is a multitude of choices available to users that are free services such as Dropbox and Flickr.

The lawsuit is also unsound in the complaint of the lack of a utility for managing files in the iOS, which is a feature that is found in Android phones. It may not pass as a deceptive marketing practice when the differences in the file management system used in the iOS is compared to those of Android's.
