So far so good, it works smoothly overall and looks great. However, I tried to connect an external DAC and it looks active, Poweramp recognized it, but it's unable to use it properly, as in no sound comes out. The phone is a Samsung Xcover 4, Android 7.0, and the DAC is an LH Labs GeekOut 1000 (v1). I can tell it's not an issue of device compatibility because it works with the HibyMusic player in the same configuration, even without an external battery. I will provide any further information you might need for the beta.
