Front facing camera defective ? topic

Hello ,
I received my nexus 6 on 2nd Jan directly from motorola.
The front facing camera seems to take very soft (bit pixelated) overexposed images , I also own a moto x 2014 and a nexus 5 the camera on these two is surely better .
Is it possible that i have a defective ff camera ?
I do have a screen protector on but i even tried the camera without a protector on , no luck
