Making calls sometimes takes two attempts

I looked through the forums and could not find anything on this that is recent. If I missed something I apologize for the re-post.

What I am experiencing is rather annoying. I start most of my phone calls in one of 3 ways. 1) from the contact/missed/recent screens in the dialer app, 2) from the contact info screen, as access by Textra (my preferred texting app), or 3) voice command.

Regardless of how I start the call, more times than not I am greeted with the call about to start (in other words the dialer opens and the number is present along with the contact info) then the dialer will close. Then I try again by either swiping from the contact list, or sending the voice command again and the call dials.

I am not rooted, on the latest 5.0.1.

Any ideas?

Anyone thinking of making the switch to Nexus 6P?

With slow updates from Samsung/Verizon combined with Samsung Pay that doesn't work with rooted devices, I'm contemplating whether it's worth it sticking with Samsung anymore. I originally thought Samsung Pay would be a game changer, but then it took months for it to be released and they have eliminated root users. The Nexus 6P seems to hit all the points for me without any restriction of root AND an unlockable bootloader. Yes Android Pay is not nearly as universal as Samsung's, but there's less bloat, immediate updates, etc etc. Reviews seem favorable.
