I don't know why you think your Samsung phone is not capable. But your questions are quite confusing, it is not clear if you are asking "when using the UAPP app" can xyz phone stream high bit death sample rate...?By the way, I'm looking for a capable phone that can stream high bit depth and sampling rate to a DAC. It sounds like LG phones are it. I don't believe my Samsung is capable.
The answer is of course yes, that's the whole point of UAPP, and I'm betting your Samsung phone can in fact do it. I have a Galaxy S7, using UAPP it can transmit 24/192 over an OTG cable to an external USB DAC, no problem. Ditto an older Moto X, same thing, and it does work with USB C ports assuming the correct OTG cable, for instance my tablet has a type C port and it too (when using UAPP) can transmit 24/192 to an external DAC with the correct OTG cable.
Why don't you just try your Samsung phone instead of assume you need something different? The key is use of UAPP, not the phone. The phone need only be OTG enabled, in other words it needs to be able to operate in USB host mode. Any phone that can operate in USB host mode should work perfectly well with UAPP and an external DAC.
