Default EXC3188-FG31 Touch Controller Eegalaxy

Hello,

i have a question. I have a fault by a device were the touch controller is faulty.

So i orderd the Controller EXC3188-FG31 and mounted it on the PCB and the device is starting (without the contoller it does not start) but the positioning of the fingerprint is not correct on some points i have the correct position but und the downside of the touch i get no reaction.

i think the contoller is well mounted on pcb and dont have any contac error, but i had the same issue on 2 devices.

Note : there is no possibility to make a touch screen calibrating, my infomartion is that a calibration is not needed by this models.

Is it possible that EXC3188-FG31 are also in different types...

I uploaded a picture of the original IC and of the spare part wich i orderd....

Can somebody tell me on the second pic (yellow marked codes) are also important or not?
