Is this Adhesive or fingerprint gunk?
I am not sure if I should clean this before reinstalling. If it is adhesive I don't want to ruin the home button. I noticed that the gasket seems in good shape and the home button was easy to get removed. Very little resistance without using heat when taking it off carefully. Should I replace the membrane if the adhesive isn't sticky when reattaching the home button to a new screen?
Is dit een goede vraag?
