Hi!
Have you double checked the soldering of the PCA8575 pin that drives this signal? There may be a soldering fault there. Another thing you could check is whether the volume buttons work (they should show a little popup on the screen with a volume meter). If the volume buttons are also not working, this could indicate a more severe issue with your PCA8575.
Regarding the touchwheel, the touchwheel *should* respond (albeit with some sensitivity issues) even without a cover installed. The touchwheel sensor IC is on the same I2C bus as the haptic motor. Are you able to get any feedback from your haptics at all? (Assuming you've soldered on a motor).
