  • (2014 Apr): Chipworks tears down the Galaxy S5: confirms this is a Synaptics/Validity chip inside.
  • It seems that the metallic border of the button is used as a ground or signal line, likely useful for the sensor itself.
  • So there is the Validity chip on a flex -as usual-, but this time there are balls to go to the upper part of the button: it is likely that the conductive lines are directly done on the inside part of the button. I wonder about the number of "pixels", because the number of balls is pretty low, so likely a not so good resolution...
  • Let's call this chip the VAL004A8 :) Take care of the die mark, dated 2008, which is confusing...
