hi everyone, after replacing my broken screen on a xiaomi mi 9, the earpiece and the proximity sensor are not working anymore

i tried to test them on the testing menu and it fails on both
i bought a new earpiece, but it's still not working. I was wondering if it could be related to a software issue?
plus, if i try to connect my phone to a laptop, it works only in charging mode but won't connect as an usb device
