Apple has published a new support document on its website that outlines a fix for users experiencing an unresponsive "Slide to Upgrade" screen after updating to iOS 9 (via iPhoneHacks).
The issue has affected a growing number of users on the Apple Support Communities, MacRumors discussion forum and social media.
Apple recommends restoring your device from an iTunes backup to resolve the problem.
1. Connect your iOS device to your computer and open iTunes.
2. Select your device. If you don't see it listed, force restart your device by pressing and holding both the Sleep/Wake and Home button for at least 10 seconds, until you see the Apple logo.
3. If you made an iTunes backup of your device before updating to iOS 9, restore your device from that backup. If not, you need to make a backup of your device in iTunes, then restore from that backup.
Apple released iOS 9 on Wednesday for iPhone 4s or later, iPad 2 or later and the fifth-generation iPod touch or later.

So much lag and instability on many devices. 4s, 5s, 6, 6 Plus, and some iPads. So much that I had to downgrade to 8.4.1. Sure, it's just a ".0" release for now, but it gives a terrible first impression considering iOS 9 is supposed to improve the experience of iOS 8. Not even close. The only improvement I saw was the battery life.
I hope Apple makes some drastic improvements with iOS 9.1.
While it's normal to have a few issues with a new release, the erratic results with some people experiencing issues and some not, and the degree of variation, is something that could be avoided if Apple did what Apple does best, and that's do the job right the first time.
When they focus Apple is excellent, when they just ship it... this is what happens. The Apple disciples will argue it's the size of the user base, or it's this or that. Apple is very lucky to have it's own cadre of supporters that push back vehemently, becoming truly combative in some cases all because they believe the company is so wonderful.
Years ago when Apple would release a new version of their computer OS, it wasn't perfect, but it certainly wasn't as sloppy as some of what they put out currently. Not only that it was not shipped with a boat load of Hype. Apple's the one that hypes everything to the hilt, if they didn't do that then customer expectations wouldn't be so high.
