Hey guys So I have two Samsung s4 gt 1905 phones one the screen is damaged and the other the motherboard, I placed the working motherboard from the one unit into the phone with the working screen. Before I put on the mid frame housing I tested and saw it power up but whenever I put on the mid frame housing, the phone gets no power. What could be the problem here?
Are both the phones definitely using a i9505 logic board and i9505 screen frame? Because i9506 logics boards do not work with i9505 / i9507 screen frames when the mid frame housing is installed with / without screws. What happens in result is no display.
