I currently have an iPhone 6s plus running iOS 9.2. I use amazon music and pandora to stream music from my iPhone and before I upgraded from 9.1 to 9.2 I was able to go:
wait a second.... then ask "what song is this?"
a few seconds later he would answer with something like "I believe this is Electrify by the Beastie Boys."
Now, since I have upgraded to 9.2 when I go:
I wait a few seconds.... then ask "what song is this?"
Instead of Syri giving me the name of the song he says variations on "let me listen a sec" or something like that. I wait a few seconds ... then he says "Sorry Melissa, I don't know that song."
What I have done:
I tested the name that tune option with an outside source (my sister's phone playing music) and it worked fine.
I uninstalled, reinstalled both amazon music & pandora.
I restored my iPhone last night from a backup I had done in October (long story there.)
Everything else that I have asked Syri to do works fine, just that bit is broke and the only thing I can think of is that it broke when I upgraded to 9.2. The little bit of researching I did tells me that it should be working the way I used to use it.
