Vibration not working on call

so, im on a call with a friend, and i wanna sleep, but ive realised that my vibration is not working anymore for any notifications, ive tried a few things that googles turned up when searching but theyre not working, it is the call thats causing this, because notifications work once I hung up.

im on an android if that matters. I dont know why its doing this now when its been fine before, so any help would be appreciated
