IPad Gen9 Front Camera

I bought the Gen9 IPad because I saw so many reviews about the improved front camera.

But my photos turned out with the worst quality I ever had for a front camera.

Shall I send a complaint to the vedor and how can I proove the camera is that bad. By sending sample images? I bought the IPad brandnew from a german supplier and had to wait 2 months, I do not want to send it back and wait another 2 months to get a new one.

any suggestions?
