You mean, the iPhone 6S camera is horrible as well? Because the SE and the 6S share the same sensor...
Sure, it doesn't have the AI-powered features of newer camera software and it also isn't a dual camera system, but I reckon it's still good. I prefer the Pixel 2 for photos to any iPhone anyway (still waiting for the new iPhone Xr/Xs features, fake bokeh effect et all, it may lives up to the Pixel's standards).
