If someone needs to know: two metal pieces at top and bottom of screen glass can be pulled out from the front (with difficulty, since they're fixed in well) and can be pressed into a new screen, they clip into place. good design.

Does anyone know where the GPS sensor is and how to test if it works?

How do we change the metal pieces at the bottom and top of the screen? they are both between the glass and the backing part of the screen and is not easy to get to.
