iOS 9 crashes often and this problem exists in the beta versions of the operating system, but it was to be expected, but in the final version it did not disappear, even after a "clean" restore done the other day.
iOS 9 crashes often in the case of unlocking using Touch ID, of attempts to access Notifications Center or Control Center, while using or leaving applications, everything seems random, although there is probably a logic "behind" these blockages.
In general, iOS crashes occur when the RAM becomes insufficient to run all actions and I think that iOS 9 it often crashes precisely because there is often no RAM available to run the installed applications or the existing functions for us.
As I told you above, the problem is not new and I have noticed it since June iOS 9 crashes often during use, but until the release of the final version of the operating system you could expect absolutely anything when it comes to a beta version of iOS.
iOS 9 crashes often
Now that iOS 9 was finally released, things had to be different and in my case the GM version of the operating system worked better than the final version, but unfortunately I don't know what Apple changed between them because things didn't improve.
I imagine that iOS 9 it often crashes due to the fact that Apple still has active monitoring services in the operating system released for users, generating a high consumption of resources that in turn affects the experience of using iDevices.
I am not the only one facing this problem, many people are complaining about the fact that iOS 9 performance they are very far from being satisfactory for iDevices, but unfortunately this happens almost every time Apple releases a new major version of iOS.
