Touch and drag to focus and expose your images, and it really works
The camera on the Moto X is not going to win any awards. It won't turn you into Trey Ratcliff, it won't get you paid for your pictures by National Geographic, and it won't keep you warm in the evenings. But it opens fast, and with the new enhanced "touch to focus" mode that came with KtiKat it takes pictures a bit better than it did before.
Previously, something was broken with touch to focus. Things seemed to focus on the center of the viewfinder no matter where you tried to move it to, and a lot of pictures showed this by being blurry and grainy. Focus and exposure are two of the most important things we need out of a small sensor camera (the third being good white balance and color correction) and part of the reason why pictures from your phone always look like pictures from your phone.
