Samsung's Camera Application
There are some excellent camera applications out there but in our humble opinion, Samsung could stake claim to having the best and we'd be fine with that. Say what you want about its sensors but Samsung's always had top notch camera software and the Galaxy S6's camera app really shines.
With the Galaxy S6, Samsung has included a Live HDR mode that allows you to see what the photo will look like before you take it. We've fallen in love with this feature and it's one that we probably couldn't live without at this point.
That's only one key feature. There are tons and we've outlined many of them here in a deep look at the Galaxy S6 and its camera application. It's an extensive piece of software and there's literally something for everybody for every situation.
