Well packed and delivered on time, the screen showed no default. Only the back of the screen (the gray part) was covered in fingerprints and therefore handled without gloves when packing. The front side was protected by a plastic film.
Concerning the replacement of the screen, besides dismantling inside the phone, I used a hair dryer set to warm to warm the periphery of the old screen to soften the glue that maintenance to the hull (and it was not useless!).
