Phone dialer pops up randomly

[nessss]

This is exactly it for me, the dialer pops up when I'm using the headphone jack adapter in my car.

I'm using a Galaxy S20.

Same Problem here. 

Extremly annoying. 

I use a headphone jack Adapter too but it happened also without that one plugged in. 

Its obviously a bug hope it will get fixed.
