And those who want 612x612 look the same as 13MP image, please start reading about resolution and detail as there is NO PHONE or DSLR or ANY OTHER CAMERA in this universe that will prevent JPEGS from degrading when changing resolution.
You are simply noticing it now, because S4s camera at 13MPx delivers enough details to notice the degradation.

It's IG's fault for forcing photos to be cropped anyways which I never understood for a photo sharing app.
If this is the case (which completely makes sense), then why when I switch my camera to 8mp (same as the iphone) the upload still comes out lower quality compared to iphone users?
Furthermore, when I upload a photo from my S4 taken with my digital camera 12mp (transferred file to the phone) the quality seems fine.
