Rearview camera

Hello, I would need your help. My grandland x is built in 2018. I kind of feel like I’m missing lines in my back camera. I mean, it would have looked different. Maybe I’m wrong, too. I can’t adjust anything. Maybe someone can help me. I also have the problem with the exterior mirrors that don’t work out, seems to be a common problem. But I can’t find a workshop. LG
