I returned my s6 Edge too. It was the most beautiful phone ever made but I just couldn't settle for the Android OS. It's better than it ever has been..... but still developers favor iOS and make better apps here. It was so hard to return.
GS4 camera is crystal clear but honestly on such small devices and social media.... you can't really tell the difference. No one is going to flag your instagram page because your iPhone 5 picture doesn't show the dust on your table hahaha
