The official release of iOS 8 was highly anticipated, but the truth is it may have been a little premature on Apple's part. Since its debut only a week ago, plenty of bugs and issues have been reported across the various compatible iPhone models.
Just seven days after iOS 8 came out to the public, Apple released an 8.0.1 update in order to address certain bugs and improve iOS 8 for consumers—unfortunately, it only made it worse.
The issues Apple addressed with the update were made to improve known bugs with third-party keyboards, compatibility with HealthKit app, and problems with apps having access to the Photo Library. The full list of improvement can be seen below.
The bugs associated with the 8.0.1 update are exclusive to the iPhone 6 and 6 Plus, and according to their owners, it killed cellular data and rendered Touch ID useless. It seems that Apple took one step forward, while taking two gigantic leaps back. We've also noticed increase response time when opening apps or navigating the Settings menu.
The process to downgrade is simple, just follow our recent guide on reverting back to iOS 7.1.2, only following Steps #1, #3, and #4—after downloading the proper IPSW file below.
In order to revert back, make sure to download the proper build for your device. Since the issues only affect the iPhone 6 and 6 Plus, we'll be providing those files below, but all other models can refer IPSW Downloader for iOS 8.0 downloads.
If downloaded the iOS 8.0.1 update, but can't or haven't installed it yet, there's now roughly 1 GB of useless information stored on your device. To delete the update, go to Settings -> General -> Usage -> Manage Storage -> iOS 8.0.1 and tap Delete Update.
If you didn't have a trigger finger regarding the new update, just wait a little bit. The iOS 8.0.1 update that rolled out this morning has been pulled, and you can bet a hot-fix is in the works.
Seems that Apple's QA department is getting some terrible attention lately—first with Bendgate, and now with unusable phones that can't make calls.
