After learning that the Nexus 5 will not be available on Verizon, I've decided to buy a Droid Maxx. My concern is the camera, and I see two problems with the camera. First, it shoots stills in 16:9 ratio only, and I almost never want to compose in that ratio. Second, like all Motorola phone cameras, the image quality is not excellent. I'm hoping to solve both of these problems with a camera app. And my question here is judging by image quality alone (megapixel counts don't matter to me), what is the best camera app that will shoot in 4:3 aspect ratio or squarer (such as 1:1)? I've looked up prior threads and seen JB+, Procapture, and Camera Zoom FX mentioned, but it isn't clear whether any of these are better or worse on the question of image quality. Thanks in advance.
