A new report from Apple Inc. (NASDAQ:AAPL) claims that more than half the devices running its iOS operating system are yet to move to its latest version, the iOS 8. The statistic was revealed on Monday as part of an update to Apple’s Developer Portal. By tracking the number of iOS distributions through Apple’s App Store.

The company found out that 53% of its users are still running older versions of the Apple operating system of which 47% use iOS 7. Only the remaining 47% users have adopted the newer iOS 8. In the two weeks that iOS 8 has been around, a minor surge of 1% was observed in the number of users shifting to iOS 6 or earlier versions.

iOS 8 prevented functioning of HealthKit Apps, Touch ID

Apple Inc. (NASDAQ:AAPL)’s iOS 8 has been riddled with problems ever since it was released. And that’s saying a lot about an operating system that is barely a couple of weeks old. There were bugs identified with the operating system on the day that it was unveiled, which prevented third party health and wellness apps based on Apple’s HealthKit Framework from functioning.

Updates only kept piling on the existing bug count

The highly embarrassed Apple Inc. (NASDAQ:AAPL) team then sent out the update iOS 8.0.1 almost a week later on September 24. This update, which was expected to address the issues with the original version, only made matters worse. Baffled users of the iOS 8 rushed to install the update patch only to find that it killed their phone’s network and Touch ID feature.

The iPhone manufacturer was forced to retract this update too and released the fix a day later. The latest version of iOS is the 8.0.2, which has finally solved the glitches found in its two predecessors, the 8 and the 8.0.1.
