No offense but what the hell are you guys talking about? Learn to use it?? What is there to learn? You point the camera and take a picture. You make it sound like the rest of us are doing it wrong.
The iPhone camera has basically no settings, especially now that they added Auto-HDR. There is, literally nothing to know about that camera software other than which icon to press to launch it and what button to press to take a picture or start recording a video. It's a pure point and shoot camera system.
Samsung's camera software is completely different. It's very complicated by comparison. There's a bevy of different modes and recording options. There is more to - yes - learn about if you want to make the most of it. If you just want to point and shoot and get decent photos in all conditions with no work or need to familiarize yourself with the camera software on a deeper level, you bought the wrong phone. Sorry.
Things like Smart Stabilization come enabled out of the box so if you don't KNOW that it's bad in a lot of situations you will end up with a lot of terrible pictures and not have a clue why. If you do Sports Recording there are dedicated Photo and Video Modes that are more appropriate for that, and they aren't the defaults. There is just a lot more to know about the camera software in a lot of Android devices compared to iOS and Windows Phone's camera software, which are quite simple by comparison (yes, even Nokia Camera is pretty simple compared to Samsung's camera software). If you want to make the most of the camera in this phone, there *is* a learning curve. It is not an iPhone, and it doesn't have an "Intelligent Auto" system like Sony's devices.
That's "what the hell we were talking about," and it makes complete sense when you decide to be less argumentative and actually think about it.
Pointing and Shooting on Auto Can only get you so far, on any camera. Even if the results are acceptable, it doesn't mean it's as good as it could be. No one's telling you to change the way you use your phone
EDIT: Anyone here tried Camera Awesome and can give a cursory review of how it performs? I don't like Camera Zoom FX and other 3rd party apps. The UIs are way too messy and ugly for my taste.
