On most Android devices, the Tidal app does not know how to bypass the operating system's resampling. On MQA-capable LG phones, the Tidal app will play MQA tracks correctly but will still resample other tracks. As far as I can recall only UAPP does everything correctly, locally or via USB. UAPP is worth a try to see how it works on your DAP, and for internal play on that Sony you'll want the MQA add-on. For more reassurance about how your DAP works with UAPP, it's worth asking over on the UAPP thread I linked to above.
This still seems to be not so straightforward sucks that it has to be this way...
Is it the same story on iphones or ipad?
