I've checked the panel and the one with two large sensors is Sony made and, from my point of view, it's better than the other one, which is Sharp made. I also like the "blackness" of Sony LCD
. So mystery is solved. There are at least 3 different Xperia V if we take into consideration the screen manufacturer.
Off topic: I checked my wife's Xperia Z and it looks like it has a Sharp panel
