When removing the soft key flex cables one of the small white (LED?) pieces came up and the black adhesive is all mangled. What are the little white squares? should they be connected to something? I haven't been able to find them anywhere and they aren't shown with the replacement daughterboards I have looked at either. I am planning to replace the mid frame as well as the daughterboard so do I need to peel the white squares off and stick them to the new frame? Thanks.
