I have an iPhone 5C and I know that iOS 11 is not suppose to be compatible.  However, can I expect iOS 11 to pop up as an update on my 5c?  If it does, I will elect not to install it, however, I think at least once an update I didn't want decided to install itself.  If iOS 11 does that on my iPhone 5C, what will happen?
