Ah, I see, you meant using only an OTG cable and not the adapter you already have.
Let us know how you do with it once you receive the M8 and OTG cable of choice.
I was quite impressed with the LG G2's seamless integration. That's my friend's phone in the picture I posted and he was able to transfer a bunch of FLAC files from my thumb drive and play them through the G2's native music player app in all of about 1 minute.
I believe the Note3 will be the same.
