The number of people using the iOS 8, the latest version of the mobile operating system of Apple Inc. increased to 68% as of January 5, 2015, according to the latest data published on its App Store Distribution page.

According to Apple, the percentage of devices using the iOS 7 is 29% and the share of devices still using the older version of the iOS is 4%.

The new figure shows that Apple continues to attract the users of its devices to upgrade to the iOS 8. Last December 22, the rate of devices running the iOS was 64%, up from 56% on November 22.

Apple’s data includes the upgraded and new devices installed with the iOS 8. It is possible that the latest gains were partly due to consumers receiving new iPhones and iPads as present during the holidays. It is also possible that some people decided to download the iOS 8 on their devices.

iOS 8 was introduced in September last year

Apple Inc. released the iOS 8 on September 17, 2014 and it was immediately available for the iPhone 4S, 5, 5s, 5c, iPad 2, third-gen iPad, iPad Air, iPad mini and iPad mini with Retina display. The company released the mobile operating system ahead of the launching of its two iPhone 6 models last year.

The five key features of the iOS 8 include the Healthbook application, Siri sing recognition, time lapse camera, phone calls and messages on users’ Mac and better notifications.

The iOS 8 was the second new mobile operating system released under the direction of Apple design chief, Jony Ive and head of software, Craig Federoghi.

iOS 8 technical problems

Apple received several complaints after releasing the iOS 8. Some users experience problems with the battery life and Wi-Fi connection on their devices when they upgraded to iOS 8. In other words, the mobile operating system runs worse on older devices as the app crash rate increased.

The iPhone and iPad maker released the iOS 8.0.1 a week later, but immediately after users reported that their Touch ID sensor is not working and no mobile service even if they are in their coverage area. Apple released another update, the iOS 8.0.2 to fix the Touch ID sensor and cellular service issues.
