It's been a week since Apple launched iOS 8 but hours after releasing version 8.0.1, the firm pulled the update due to serious problems. Luckily there is a fix and iOS 8.0.2 will arrive soon. See also: The best smartphones of 2014.

Instead of fixing minor issues, the iOS 8.0.1 update caused some serious problems, leaving users unable to use their iPhones properly. The firmware stopped the Touch ID fingerprint scanner working and cut off all phone calls.

"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," said Apple which is "preparing iOS 8.0.2 with a fix for the issue, and will release it as soon as it's ready in the next few days."

iOS 8 comes pre-installed on the new iPhone 6 and iPhone 6 Plus but is also available for older smartphones dating back to the iPhone 4S.

How to fix iOS 8.0.1 bugs

For those users who have updated to iOS 8.0.1 and are suffering with the major problems, Apple suggestion is to reinstall the operating system through iTunes. You'll need the latest version, connect your problematic phone, do a backup, download the correct file here, check for an update and update your iPhone.

Unfortunately for Apple, the iOS 8 issues are the only ones plaguing its new smartphones. The design, particularly of the iPhone 6 Plus, is being heavily criticised because the phone reportedly bends just by being in a pocket.

The video below, which deliberately bends the iPhone to demonstrate, has more than 18m views at the time of writing. Apple has put a lot of effort into making the aluminium device thinner than previous models but many are unhappy with the weakness this has created. Apple has responded on this front.
