LCD off center

[Flavor]

The LCD itself does have an area that seems to be screen, but it's not. That's what you are seeing. It is likely that you can get it shifted more to the right, so you get a bit more viewable area. There may be some small plastic on the walls that can be shaved to allow it to move over a bit. The LCD plastic itself also has some nubs that protrude a bit, and sometimes these "push" the LCD to one side. It's also possible that it's floating in there, and you can just slide it a little to the right. If that's the case, I might recommend you secure it from sliding with some adhesive under the battery compartment or perhaps with a little extra padding between the LCD and the PCB (but be careful to not put any real pressure on the LCD, just enough to stop it from floating).

Also, when you place the plastic/glass lens in front, I would recommend attaching that as far to the left as possible. After those two things, I think you won't notice it much.
