I wasn't really able to use this feature on my last phone because it drained my battery too quickly, but I'm trying to use it more on my 6P. After reading the post above, I was expecting it not to work from the lock screen, and that does make sense. And it will work from any screen on my phone, but it will not work if I am in an app. I suppose this makes some sense, as well, but I had sort of understood from friends who used it more extensively than I that it would work if an app was open, but I could be mistaken.
Can anyone clarify. Not a really big deal if this is normal behavior; just wondering if I should be looking for a fix.
Thanks,
Derrick
