Volume delay when volume button is pressed

[Remis]

I use S21 FE 5G and from past 1 month I'm facing this issue

When i press volume button it doesn't work immediately but takes 1~2 seconds to work, I'm facing this issue on all apps but sometimes it's works properly.

Is anyone facing the same issue please reply
