iOS 9.2 Beta Problems
The iOS 9.2 beta is an early form of iOS 9.2. And that means that it's going to deliver problems to you and your device. This is another reason why you might want to avoid the iOS 9.2 beta.
iOS 9.2 beta users have already outlined some of the problems plaguing the iOS 9.2 beta 1. There are issues with messages, problems with video, problems with iCloud Keychain, and more. We've also heard about issues with apps, with battery life, and with Bluetooth. All of these are common with early software.
iOS 9.2 beta 1 is the first update and it's far from perfect. If you want to use the beta but don't want to deal with problems, wait for a newer beta or avoid the iOS 9.2 beta completely.
