It's a really nice feature so go get 3.5.1!
Ah I figured that is what those were for but I only pair one phone and never really had a chance to test it out for sure. Even though I only have one phone paired though, I have noticed that when I go to BT audio sometimes the first fake led is lit up, sometimes it is the third (haven't seen the second but haven't had a lot of time with the update yet). Not sure if this is normal or not. It works regardless of which one is lit so I am not really concerned but it just seems odd.
