It works most of the time, sometimes I have to press harder on the screen, other times I have a wet hand or with sweat and it works instantly anyway
I can honestly say that right now, the only feature from the stock OS that I REALLY miss is the face unlock, but I can't give up the incredible features of GrapheneOS just to get the face unlock back
