Anyone know if there’s a way to nondestructively replace only the glass circle (roundlet, surface, whatever you want to call it) on the iPhone 7 home button? This would be for the purposes of modding the colour of the button in order for it to match a black display installed on the silver variant of the phone. Incidentally, anyone know of someone who has successfully pulled off this colour swap? Thanks.
Ive done it using heat and OEM button. First attempt to use glass only from ebay was unsuccessful. Touch didint worked. So ive used spare button as a donnor . And regarding adhesive- UV curable same as you wold be using for digitiser only repair
