What is GPIO_GRAPE_IRO_L on the Touch Connector responsible for?
I've got an Ipad with a ripped touch connector, all damaged pads I marked red in the image. Only pin 16 aka 23 is problematic. In the schematic it's listed as GPIO_GRAPE_IRO_L. Aside from trying to figure out how to fix/ bodge it, as there is no connected component near, with the connecting pin being in the middle of an IC and it's brother on the B side, what does this specific pin do? Is it redundant or maybe doesn't play a role for basic single finger touch and is only used for something like 3D touch?
I've never read a schematic before so I'm a bit clueless...
