In most cases, it leaves me with useless shots.
I dont know anything about settings, i just want to hit the camera button and snap a photo.
This is what I think is the case for most that are not satisfied with the camera. Unfortunately, camera settings must be adjusted manually in order to get a good shot. The camera and phone itself just cannot know what you are trying to take a picture of....so any kind of auto setting will not work.
I have yet to see a camera app on the market that really helps with this. An app with like 12 presets based on lighting, distance of object, etc. After choosing a preset, all camera settings are adjusted appropriately. Most people don't know what ISO to set their camera at (among other settings)......an app like this would solve the issue.
