mobile

Hello,
I reset my z1c to factory settings and now I'm trying to get the look and feel back as it was before.
I made screen prints from my xposed modules but I did not do this for the normal phone settings.
When I plug in a headphone I always get the message 'Headphone connected', this message stays on top for a short while before disappearing.
I know I did not get this before resetting my phone and I like to switch it off but I dot know the application responsible for this notification.
I know there is a big list of apps in the manage notifications section of settings - personalisation.
I guess it must be one of those apps in the list but I do not know which one.
I know I can switch them off one-by-one but this is a tedious operation I'd like to avoid.
Does anybody know which app to switch off in this list?

Thanks
