which can help if you're blowing up shots to enormous proportions. But it also has one big Achilles' heel. When you fire up the Galaxy S5's camera from the lock screen, it takes a good five or six seconds before it's ready to snap a shot. On the iPhone, I can jump from lock screen to taking a picture in about 2.5 seconds. If you have to wait over twice as long as competing phones to use the Galaxy S5's camera, well, that's a big strike against it.
