iPhone SE modelo 3d

In this model, there are a couple of not very pleasant nuances, the joints at the edges of the roundness are illuminated at a different angle, even in the pictures you can see that these roundness as if bulging. In fact, they do not stick out, I tried to solve this problem for a long time, the problem has not been solved because of my inexperience( this is my first work in 3D modeling). You can also note the turbidity of the glass used in the camera, the camera is actually quite good, there are even lenses inside, you just need to change the front glass of all cameras to a more suitable material. Antenna back of the phone( 2 grounds on the back of the phone) curves, and of all kind. The rest of the phone is not bad, I hope for your understanding.
