The dimensions are good unless you notice a slight shift in the place of the proximity sensor and the front camera so I think I have positioned the protective film (photo support). Obviously, it is difficult to avoid air bubbles and dust because it would require to be in a clean room.
After touch is different, it is a bit "rough". Lit display, there is no loss of visibility and no loss of tactile function.
PS: The picture visible dust are those of the scanner glass for most
