I've had this problem for awhile. Got mine back in February, the camera issues probably started after mid-summer. When I was ready to take a picture with the front camera, it would bring up the error message (couldn't capture the moment, too long of a reboot time). Then a few weeks after that, the rear-facing camera started giving me the error message when starting up the camera app. This is the only thing I really hate about the phone. I even factory reset it a few times, and without installing any new apps, the phone still gives me the error message. My phone's gotten both updates so far, and I think the first update (done between February and mid-summer) started the issues. The second update seemed to increase the number of times the error message comes up.
