I had bought a while ago a refurbished OEM display for my old iPhone XR. Problem is that new screens touch is not working even though it turns on and shows everything as it should. I was reading long ago something about multiple display manufacturers and that there was an issue that one model was not working properly with others display. I think I have this issue but I have no idea how to confirm as I don't know how to check which model I have nor what display model it is (probably have serials inside though). I am thinking of buying a JH display now because they are cheaper and apparently work with every model, seems also somewhat close to original (hopefully). What I want to know if this is not some phone issue that needs to be fixed or it is just the model problem.
