Do you know how to get the new UI for Assistant on the bottom center of the screen back? On my 3XL from Verizon i just got the latest January security maintenance patch, and afterwards, in AA, the Assistant UI reverted to being at the top. I also noticed that when you have the latest Assistant UI, and say the "Ok Google" command in the car, Assistant does not time out ever vs the older UI where Assistant is on the top of the screen. Every now and then Assistant will time out, and you have to say the key phrase again. Sometimes that tends to get annoying. I tried to force un-install AA to v 4.8 to no avail yet. :-(
