I've found

When in the start and back menus when I press down on the d pad my voip is turned on.

When in the back menu sometimes the bottom of the menu is cut off and I can't select items or even see them. This is fixed when I leave the menu and return.

I have noticed that the alarm clock dosnt attract zombies like a gun shot dose. Not sure if this is intended but a loud sound not even attracting any zombies seems wrong. Also I can't look at the clock when it's in my hand unless I go to set the alarm.

When loading the shotgun from the back menu it only loads one shell. Have to drop the shells to load all at once or put the shells in the quick menu to load all.
