Four reasons why you may want to wait on iOS 8

The latest version of Apple’s mobile operating system, iOS 8, is rolling out to iPhone and iPad users today. iOS 8 brings a lot of great new features, including third-party keyboards, interactive notifications, and eventually, deep integration with OS X Yosemite, but as with any operating system update, along with new features come a few new bugs.

Here are some you should be aware of when you update your iPhone or iPad:

1. iCloud Drive won’t be fully functional until the next version of OS X comes out

One of the coolest new features in iOS 8 is called iCloud Drive, which promises cross-platform cloud storage across multiple devices, much like Dropbox. There’s one problem: It’s not working yet. iCloud Drive is incompatible with OS X Mavericks, and won’t really be fully functional until OS X Yosemite is released later this year. Developers of apps such as DayOne, Notability, and Clear are even warning their users to resist turning on iCloud Drive, otherwise certain settings and files won’t sync correctly. When Apple prompts you to upgrade to iCloud Drive on iOS 8, you should choose “Not Now.”

2. Healthkit is not ready yet

If you were hoping that iOS 8 would be the start of a new you thanks to fitness and health tracking capabilities built into Apple’s HealthKit platform and the new Health app, you may be putting it off for another few days. Although several Healthkit-enabled Apps were updated on the App Store this morning, they have since been pulled because it appears that HealthKit is not yet ready and Apple has found at least one issue. Apple is reportedly contacting HealthKit developers to warn them about the issue and that it might not be an easy fix. Brian Muller, developer of Carrot Fit, tweeted that he received a call and that it “sounds like HealthKit won’t be working at all this week.”

Apple has since confirmed to the Financial Times that there is in fact a bug that is affecting HealthKit apps, and that it will be addressed by “the end of the month.”

3. iOS 8 will interrupt your regularly scheduled Dropbox backups

Not only is iCloud Drive having issues, the software it seeks to replace — Dropbox — is also struggling with iOS 8. If you use Dropbox to backup your photos and videos to the cloud, you might want to hold off upgrading to iOS 8. Dropbox Support tweeted that they’ve found an iOS 8 compatibility issue, and it not only affects the Dropbox app, but also the photo-oriented Carousel app. Dropbox has suspended the Automatic Backup feature, but before the full fix is in, Dropbox users should not delete their photos and videos or they could be lost forever.

4. If you’ve got an iPhone 4S, consider leaving it on iOS 7

Apple will stop selling the three year old iPhone 4S when the iPhone 6 goes on sale this Friday, but it’s still eligible for an upgrade to iOS 8. If you’re sticking with your old device, you might want to stick with the old version of iOS as well. According to Andrew Cunningham at Ars Technica, iOS 8 isn’t a great experience on the iPhone 4S. Launching apps like Safari can take up to two seconds, many of the new features — like expanded Spotlight results — seem to want more screen space than the old 3.5-inch panel can offer, and animations are “choppy and inconsistent.” The iPhone 4 had similar performance issues when iOS 7 was released last year, and they were largely addressed in the first update.

If you’re positive that you want to update your iPhone or iPad to iOS 8, bugs and all, then you can find the update in Settings > Software Update.
