You can't feed the Mojo an analogue signal, so if using the DAC on the phone then Mojo wouldn't work regardless. I would suggest UAPP get their engineering department to talk to their marketing department. There are plenty of users who use their Android phone with Tidal (I'm talking about 44.1kHz HiFi, not MQA) but the Mojo either reports 48kHz sampling rate or 192kHz sampling rate which means that Android SRC is re-sampling the file. Has nothing to do with the phone's DAC.
Splitting hairs. All that matters is that UAPP bypasses all internal Android audio processing and let's your high price DAC handle it.
