The other LCD with touch HS was returned to the seller for exchange against a functional screen.
Advantage for the moment, an attractive price and speed to ship to.
Depending on the vendor's ability to manage its service, I reserve the possibility to significantly up its note.

The seller immediately took care of the problem and I forwarded without charge a full iPhone LCD that was just perfect. I received my package by courier the next day.
As a bonus, I had the pleasure of having a small gift that will limit the risk of breakage of the new all beautiful brand new screen.
Very serious seller, you could trust him and rely on him in case of problems.
