If they get everyone in to change screens there won’t be any service availability for a while..plus all the logistics to cover all the markets with parts. I was hoping the UV is working. Someone posted that it works even if you let the screen in the sun with the roof open. I had also seen posting with before and after and it looked clean.
My guess is that it won't work for every screen, some of them are really bad. They will probably end up replacing the really bad ones. And we don't know if the UV treatment will prevent the screens from getting to a state that is unrepairable.
