My vibrator sometimes work sometimes dont

So my samsung a30 vibrator is kinda weird

Sometimes it works, but sometimes it doesnt

I did like factory resetting 3 times,

On the first factory reset vibrator works,

And on the second reset vibrator doesnt work

On the third reset, vibrator works

Is this software issue or i need to replace the vibrator
