Although Qualcomm's range of Bluetooth products is
pretty extensive, I could only find mention of aptX HD
support inside its top - end CSR8675 and CSRA68100 platforms.
One other neat addition is the fact that TouchWiz now
supports theming by default (and the customization is
pretty extensive, with even Samsung's apps changing their appearance based on the theme selected), to let the user change the look and feel of their devices right from the start.
