[Bangle.js 2] modification: add buzzer, bigger battery, more switches, minus HRM

I have finally designed the new case for my modification and 3D printed and assembled the watch. It has a piezo buzzer, the same motor (moved to the right side wall), USB type C charging port, 350mAh battery and 4 additional switches. attached is a picture of the assembled modified watch. I will show some more pictures later.

As I explained before, the HRM module was removed and 3 pins (D32, D24, D22) from the header was used to get 4 switch inputs.

Everything works as I expected, but the accelerometer stopped working. I have checked the components (the accelerometer chip and caps and resistors around the chip) visually (with a magnifying glass) but couldn't find anything wrong.

I wonder if the power for the accelerometer chip is through the HRM header. Is there anything I can check? Below is the reading of the accelerometer.

Bangle.getAccel()
={ x: 0.00012207031, y: -0.00012207031, z: 0.00012207031, mag: 0.00021143198,
  diff: 0 }

These values don't change when I move the watch. So the question is whether removing the HRM module can affect to the accelerometer. Any thoughts?
