Hello Ifixit I encountered an Iphone 7 plus having an issue on fingerprint sensor the touch id has the same serial with the board itself but when i already boot it up and setting up the fingerprint the fingerprint tab just displays their and not noticing my finger . Double tap to go down is okay and homebutton is working so fine . Can you help me fix the issue ? Thanks i already tried to rearrange the flex cable but still didnt work tried resetting it also etc. nothing works .
Give the display connectors and cables a good inspection. If you creased or tore one of the cables, that could lead to touchID issues. Can you try a new screen?
