Apple made a statement overnight apologising for the "great inconvenience" created by its flawed iOS 8 operating software.
The company has been the subject of criticism after it released the latest version of its mobile operating system earlier this month. It's 8.0.1 update, released yesterday designed to fix problems with its health app, caused further headaches, with some phones to losing network signal and functionality on the Touch ID fingerprint scanner.
We apologise for the great inconvenience experienced by users, and are working around the clock to prepare iOS 8.0.2 with a fix for the issue.
This isn't the first time a software release hasn't gone smoothly for Apple: when it released iOS 6 in 2012, its native Maps app, which replaced Google Maps, came in for fierce criticism.
The company has also come under fire in recent days over its "bendy" new iPhone. Just days after its release in the UK, some users have found the phone is so delicate, it warps in their pockets.
Apple has yet to say anything about that - but it recalls a similar episode in 2010, when a flaw in the design of the iPhone 4 caused users to lose signal when they held it up to their ears. Back then, Apple released a plastic "bumper" to fix the problem.
Here's a video from US tech blog Unbox Therapy of the iPhone 6 Plus - Bendy Edition.
