Nougat lock screen

Finally received update to android 7.0 this morning! Build Number 32.3.A.2.33

Patch level March 1. It's a bit "different", what bugs should I look out for or tweak?

So far I would like to remove the voice search from the lock screen or at least make it more secure. I removed the cammera icon from there ages ago.

The search is the icon on the lower left of the lock screen. The rest are different but should give you the idea. Curiosly enough when I was underground with no service this morning after the update the mic icon turned into a phone icon which is good enough, but then it turned back.

The setting stays at "none" but seems like the lock screen "forgets" about it so when the phone reboots the lock screen shows that microphone again. Looks like a bug to me.
