Rear camera is too blurry and Front camera is straight purple.

Hello everyone. This phone I am having is perfect except for the cameras. Whenever I try to take photos, the rear camera seems to not focus at all. I mean no matter I try to make it focus, it doesn't change the focus. It is also seen in third party camera apps too. The front camera is straight up purple except when shown in direct sunlight it gets fixed. Also, whenever I try to use the ultra wide camera, it says "Camera Failed". Do I need to change the camera? Or is it any software related issue?

Forgot to say that front camera sometime works using Snapchat.
