Adding another one
Phone: Essential PH-1
OS: Android 8.1.0 (May security update)
Poweramp Build: 709
Why it Should Work: It uses the Snapdragon 835 processor. Essential also makes their own Bluetooth headphones that are marked as Hi-Res Audio using Qualcomm aptX HD Audio. The PH-1 also does not have a headphone jack, so all audio must be over the USB port, if that makes any difference. I think the USB to 3.5mm adapter Essential includes in the box is some kind of Cirrus Logic DAC.
