Adoption of iOS 8, Apple’s latest mobile operating system, has come to a halt.

As of October 5, almost three weeks after its release, iOS 8 adoption amongst users of the iPhone and iPad is at just 47%.

To highlight the slow dissemination Apple has faced, adoption was at 46% just six days after its release on September 17. On release, iOS 8 encountered problems which left thousands of Apple users frustrated.

iOS 8 was reportedly causing apps like Facebook and Dropbox to crash 78% times more than its predecessor iOS 7. The average crash rate recorded on the iPhone 6 and 6 Plus was 3.56%, higher than the 3.57% recorded for iPhone 4, 4s, 5 and 5s, according to app analytics firm Criticism.

iOS 8 was also a large download, forcing users to delete content from their phones to make room for the installation.

Apple pulled out the iOS 8.0.1 update from the App Store over several user complaints because of dropped calls in addition to issues with the Touch ID capability and data service.

On September 25, Apple released iOS 8.0.2, which has reportedly solved many of the issues users were experiencing. However, Bluetooth connectivity failures are still being found by some users.

Almost 70% of iPad and iPhone users upgraded to iOS 7 from iOS 6 in the same period.

In the UK, 9% of iOS users updated to iOS 8 within the first 24 hours of release. The earliest adopters were found in Norway, where 13% of the users updated within 24 hours. iOS 8 contains several new features for developers and users. Healthkit – a new app – generates the most buzz because it enables data collection and storage from health and exercise apps.
