People who experience this problem, do not panic.
I've reported the bug to Apple, only they asked me extra info 'the crash logs but you should do if you currently suffer from the bug now I no longer suffer from the bug so that I myself may be crashlog to pick up but does not make much sense because my iPhone 5 this problem currently experiencing.
This crash logs are necessary if you want Apple investigating this further.
People who experience this problem can otherwise the crash logs and send me do not forget to report what type of iPhone, iOS, what Version / Build number, and which provider and which country your problem!!
