I have a Nothing phone 1 and was on a job and somehow got dust inside the phone and it is making the camera’s picture quality obviously terrible. I can get a glass back but none of the places that I asked have the adhesive to come with the back. My question is what adhesive do I get for the replacement of the back glass to seal it up nice and tight. Also I am aware I don’t need to replace it but it has a scratch so I might as well do that while I am there as it isn’t that expensive to get the part. Thanks for your help.
