My camera freezes several times a day when I try to open it in the messaging app, anyone else having this issue?
Nope, but I also don't have an iPhone 6 Plus yet either. Have you upgraded to the latest iOS version or restored your device and set it up as new? That is what I recommend, and then if the problem persists, make a genius bar appointment with the nearest Apple Store...
It only happens in the messaging app so I am figuring its a software issue!
