1. Samsung Galaxy Note 8
2. Stock Android 8.0.0
3. Whatever DAC the note 8 has. I have a previous post in this thread, only have OpenSL ES Hi-Res Output available, and that only up to 192hz.
Hi-Res support hasn't worked for quite some time since switching to Android 8.0.0 but I know the phone is capable since I've had it before.
