Note:increase the sensivity of Yaw, Pith and Roll to the high value in HeadMob app. Then write below code in FreePIE:
def update():
x = filters.deadband(filters.delta(math.degrees(android[0].googleYaw)), deadband)
y = filters.deadband(filters.delta(math.degrees(android[0].googlePitch)), deadband) * -1
mouse.deltaX = x * 3
mouse.deltaY = y * 2.1
if starting:
deadband = 0.09
android[0].update += update
