All of a sudden a few days ago, the camera shutter won't open on my 4S. I can look at my camera roll, but just can't open the shutter to take pics. Tried: 1) Enabling the camera restriction to "on" 2) Closing the camera app via taskbar and reopening 3) Turning phone completely off on 4) Resetting phone (home+sleep until the Apple logo reappears) The only thing I haven't done is done a full blown restore, because from what I've seen online it looks like 75% of the people who've had this problem ended up having the phone replaced since it appears as if it's a hardware problem and not a software problem. Any idea if this is truly a hardware failure? I'm not sure what Apple would charge to replace the phone (no AppleCare) but I don't really care to pay a couple hundred bucks to replace a phone 3 months out of warranty since getting two years out of a phone these days seems like too much to ask I guess. Not really interested in replacing it with my full upgrade coming up in May and rumors of a summer 5S launch. Hardware or software? If I can confirm it's hardware, I'd rather skip the hassle of restoring the phone.
