I finally have free time to try this, but there are now two links for every carrier on that page. Is the second one the camera update?
Edit: Flashed the first one. One of the things that's been bugging me is that the vibration duration during typing has decreased every time I've set up the phone. It starts at 20ms and then it decreases to "System Default" (whatever that is) a few minutes after turning it on for the first time. I don't know if it's relevant, but it's super mysterious. (Maybe it's just because of the update that gets pushed immediately?)
SUBEDIT: It is the update. Mystery solved.
Edit 2: Strangely, it's happening less frequently but it is still happening. I don't know what to make of it. I guess I have to get this replaced with another one that will probably be broken (considering this is my third and they've all had problems). Maybe I should try updating first?
Edit 3: Another curiosity: I rooted and used RSD Lite, which should leave the q/e at 1/1. Yet it's at 0/1.
Edit 4: At the risk of jinxing it, it looks like the update fixed it. Will confirm after a day or two.
