My Nexus 4 camera is better than my Nexus One and my Nexus S. Did the Galaxy Nexus have an amazing camera or something? All I heard was people complaining about that one too.
It seems your comment doesn't fit with reality. ;)
aiaf is likely talking from a relative perspective, and the G1, Nexus One, Galaxy Nexus S...they all were somewhat in line with contemporaries. The Nexus 4 was a massive regression compared to its kin.
I don't think it is your case..But I just want to tell you my personal story about why my dad kept on complaining that the camera is bad on Nexus 4. It turns out that there is a screen protector on his Nexus 4's back that actually COVERS the camera. The other two Nexus 4 I bought for myself and my bf also had screen protectors on its back but it was not covering the cameras.... So yeah..
