When I looked at my phone today there is a crack forming on the right side of my phone am gutted. I assume this will not be covered in the warranty. The annoying thing is that I have been so careful. Never been heavy handed or dropped the phone and this has appeared. I have never had a crack on a phone before so don’t know if they can be changed or how easy this is.
Does anyone know if this can be done? How do you do it and is it expensive?

Thanks for any help.
