— -- Apple's new operating system may look pretty, but the rollout hasn't been smooth for everyone.
Many people have taken to Twitter to complain about issues they say they've experienced with iOS 8, including slow download speeds, sluggish performance and problems with both Apple's native keyboard and third-party keyboards.
The majority of the comments haven't focused on the aesthetics, but rather functionality issues that have been apparently brought on after users upgraded their devices to iOS 8.
Then there's the alarming "accidental selfie" feature of iOS 8 pointed out by TechCrunch.
One of the new features of iOS 8 is the ability to easily send audio, video and photos to friends via iMessage. However, when fiddling with the new features, some users have found out the hard way that one click is all it takes to snap and send an accidental selfie to a friend.
Apple did not immediately respond to a request from ABC News about whether an iOS 8.0.1 update could be in the works. However, the company told ABC News in a statement last week that it's hotly anticipated HealthKit would not be released on the new operating system as expected.
"We discovered a bug that prevents us from making HealthKit apps available on iOS 8 today. We're working quickly to have the bug fixed in a software update and have HealthKit apps available by the end of the month," the statement said.
Aside from HealthKit, Apple's new iOS is packed with new bells and whistles to breathe life into your old devices.
The Family Sharing app allows up to six people in a household to share each other's iTunes, iBooks and App Store purchases. It also enables families to keep up with each others' photos, calendars and locations.
A "smart keyboard" that can suggest "contextually appropriate words" to complete your messages will be rolled out, along with the ability to seamlessly send video and audio iMessages, among other updates. (That is, if the keyboard even shows up on your phone.)
