Why does the motor on the Redmi A3 take so long to start and stop?

Thank you for your support of Xiaomi products. Our products use a 1027 motor rotor and eccentric vibrator, heavier than 0830 when the motor turns to start and stop, to overcome its weight and inertia, resulting in the motor start and stop time being longer than 0830.
The 1027 motor rotor on the Redmi A3 refers to a component in the phone's vibration motor. In smartphones, this motor is responsible for generating vibrations for notifications, alerts, and haptic feedback. The "1027" designation indicates the motor's model or specification. It plays a role in providing tactile responses and enhancing the overall using experience by adding physical feedback to touch interactions.
