I can't BELIEVE your post went by without one single comment. Unreal.
Let me make sure I've got this correct. You went by an AT&T store, took the picture on the left with your iPhone 5 and then took the picture on the right with the display S4. Then you posted them here for all of us to see just how crappy the camera on the S4 truly is when matched up against the iPhone 5? Have I got it right so far?
So, how did you get the picture off the S4? I mean, the iPhone 5 picture is sitting right there on your personal phone ready to be posted. But I can't figure out how you got the original picture off the display S4. Maybe you went into the browser and logged into your email account and emailed it to yourself? Are you sure you logged out? Otherwise, there might be someone out there with access to your email account now!
Seriously...the lengths some people go to to make Android look bad in comparison are just sad.
