Gt-i9100 No Soft Buttons
I run a cell phone repair store and have recently run into some problems i'm hoping you guys can help me with.
I was bringing in the Samsung Galaxy s II completed front assembly parts for the last while and repairing broken screens.
Recently my supplier ran out of black galaxy S II fronts so I ordered white in place of them.
After installing the motherboard we realized there were no soft buttons, the home button clicks but the two touch buttons don't work.
The black fronts I have work but the white ones dont, is there a difference between the 2 phones? are they not identical and are the parts interchangeable?
I found a new supplier and ordered some Black assemblies and none of the soft buttons work on those either!! I don't understand!
Is there a compatibility issue here? I know the motherboard is good, is there a driver for the soft buttons or something? Some sort of firmware?
