I'd like to preface this with the fact that I've owned every iPhone since the original. I love iOS for the most part and the polish of the apps in this ecosystem is pretty hard to beat. Here's the problem. My 5s freezes for 2-3 seconds when I unlock it. Stock iOS apps crash for no reason. 3rd part apps open and freeze for a few seconds before I can use them. I've done the hard reset. The clean restore. Nothing seems to fix this issue. iOS, and my iPhone, for the first time feels buggy and the luster of Apple's product feels tarnished to me. Anyone else having these issues? Anyone have any fixes?
