How ridiculous that you suddenly need an Assistant Menu to answer a call after an update. Why couldn't we have just tapped on the phone icon as always to answer calls. This is stupidity personified and that menu is always in the way, even though it can be moved. I should've known from previous experiences not to do any updates. These updates cause havoc with the cellphone and I never see any improvements.
simply have this deactivated
Settings → search above "Assistant Menu" → kill it
