I don't know how you got it to work with your Note 4.. I have a Note 4 running Android 5.1.1 and I connect my Fiio Q1 to it using a Cable Matters OTG cable and the audio still goes out through the phone speaker. I tried HibyMusic too with the same results, I got the DAC to work though, after restarting my phone 2 times and keep plugging the otg cable in and out multiple times. Why is it acting like this, I don't want it to be so complicated to pair the Fiio with my phone. When I got it to work it sounded great and worked hours, until I got a call and had to unplug the DAC. When a call came in whilst music was playing there was a very loud screech, I thought my phone blew my DAC but it still works great (tested on computer). Plugged it back into my Note 4, same issue, audio out through speaker.. I'm very disappointed, not with the Fiio, it's great and I did need it for my laptop, but I want to use it with my phone too and I don't want this hassle. *cries* I blame Android
