Vibro motor is getting really weak. What used to be a solid vibration now sounds like a dying droid short of "breath". Is there a way to disable the start-up/shut-down vibrating and all other system haptic feedback? Not the vibration options that can be toggled in app and system settings, but actual motor disabling. Found this article
but I am not sure which system app responsible for the motor to use.
