Apple's new iPhone and iPad software comes with better battery life and a new Siri interface. It might also come with bugs.
Apple customers are reporting on Twitter and other online forums that apps on their mobile devices are crashing when they update the operating system to iOS 9. iOS 9, the latest version of Apple's software for iPhones and iPads, rolled out to consumers on Wednesday.
"iOS 9 was cool, but now all my apps keep crashing so now I hate it," tweeted Isaac Miltimore.
The problems bring back memories of Apple's iOS 8 update last year, which caused certain devices to experience . Subsequent updates to fix the software ended up creating their own problems. These problems aren't rare -- Apple pulled its , and issues often arise with the introduction of new software.
"The big picture here though is that this is the standard environment for a new operating system launch," said Piper Jaffray analyst Gene Munster. "There are always going to be a spectrum of bugs but they should be solved within a few days."
Since Apple's official iOS 9 launch, the adoption rate of the new operating system is a little more than 20 percent, according to Mixpanel, a third-party mobile analytics firm. So far, the latest version is being adopted at a faster rate than previous operating systems.
Munster expects numbers to keep growing despite the reported bugs, which would allow the Cupertino, Calif., company to solve them more quickly. "Apple can't get an OS to be stable until they have the full force of their base using it," he said, noting that any glitches are likely the result of the combination of apps and hardware on users' phones. As users send diagnostic information back to Apple after downloading the iOS 9 upgrade, Apple will be better able to fix the bugs.
Yet customers didn't hesitate voicing their grievances. Here are a few more related tweets:
"This iOS 9 update... App crashing and ugly fonts." --@stephayson
"Y'all updated to iOS 9 for the extra hour of battery but you'll regret it when it starts getting laggy and crashing" --@Nycphoria_186
"Outlook app is crashing after iOS 9 update. Had to uninstall and reinstall the app to get it to work again." --@bananza
"Does anyone else have apps that keep crashing after you got IOS 9???" --@emm_zeddis
At least one complaint reference battery life, but it's unclear whether that's been a bug associated with the update.
iOS 9that make iPhones and iPads more able to predict an owner's needs and interests. For example, based on user habits, a device can load up music selections ahead of a regular morning runs, or automatically suggest apps. iOS 9 also improves battery life and gives the Siri voice assistant a new interface, allowing it to remind a user of appointments without being told to ahead of time.
