No. The DAC chip on most smartphones is about the size of your microSD card. Another thing is that smartphones are supposed to have many other functions besides audio playback so there's no point stuffing a half match box sized DAC into a smartphone. Have you seen how big DAPs are? Those are the kind of players which have that match box size of DAC with a huge amp.
I just want to let people know that any phone with a Qualcomm Snapdragon is going to have the same DAC...the Qualcomm CPU itself. That is why the Samsung phones that use Samsung processors (that isn't a snapdragon) have an added seperate DAC.
