Here's the xml (tw_status_bar_expanded), with the line containing the button layout in red:

This is most definitely the layout xml that is being used. The line in question also refers to "@id/clear_all_button". I'm away from my own computer right now so I can't remember which smali that goes back to (it actually shows up in three smali files, but I think I narrowed it down to one that concerns me), (EDIT: it's \SystemUI.apk\smali\com\android\systemui\statusbar\phone\PhoneStatusBar.smali) but as I'm 100% useless at reading code, it doesn't help me much anyway.

But I appreciate you helping, if anything jumps out at you let me know. Thanks a lot!
