It's not over thinking it. Samsung under-thinks its ideas.
The S4 has a feature that allows you to take a picture with the back and front camera at the same time.
Samsung says "hey sometimes you want to take a picture of your friends/family and be in that picture too so this feature will add you in there.
Ok, interesting concept. How did they execute it? the final pic looks like someone copy and pasted your face into the pic.
Is there a better way to do this? yes, ask someone else to take your picture. Mankind has been doing that since the camera was invented.
Better implementation than affixing filters into the camera app.
Apple so wants to be Instagram, Twitter, Facebook and everything else.
Always late to the party.
