I have a samsung s3 lte with a broken camera lens cover. I would like to replace it without affecting the warranty. In order to replace it carefully, I have to take off the middle chassis and cut the tabs on the camera lens cover part which hold the camera lens onto the chassis. Please can you tell me, If I am careful, is it possible to remove and replace the chassis without affecting the warranty? I.e. will I be able to do this without leaving any "tamper" evidence?
