Process of Smartphone Audio

[FCTPWS]

I've Tested 2 Smartphones About its Audio Performance. SAMSUNG S4 & Huawei GR5. That S4 Has Great Audio Perfrmance than GR5 Model. Applied Same EQ Settings for Both Devices & GR5 Has No Crear True Bass Feelings. But S4 Has Best Bass Effects & Sound. So What is that Different? is that Hi-Resolution Audio or Something?

Audio chips between devices differ.
