    Default USB OTG host mode support and AptX on the GE S4?

    Can anyone comment on whether the GE S4 includes support for USB OTG host mode and the Apt-X bluetooth codec?

    Thanks

    I believe aptX is supported. When connecting a pair of Phiaton PS 210 BTNC bluetooth earphones with aptX to my S4 GPE, I see the following log output from doing a logcat:

    D/CODEC_IF( 1543): codec_if_open: opening libbt-codec_aptx.so...
    D/CODEC_IF_MOD( 1543): codec_open: codec_open
    D/CODEC_IF_MOD( 1543): codec_open: apt-x encoder initialized successfully
    D/CODEC_IF_MOD( 1543): codec_open: version : 1.0.1.0
    D/CODEC_IF_MOD( 1543): codec_open: build : AND2.3-000
    D/CODEC_IF( 1543): codec_if_open: codec module opened (v0.1
    D/CODEC_IF( 1543): codec_if_close: codec_if_close hdl 1102352388
    D/CODEC_IF_MOD( 1543): codec_close: codec_close
    D/CODEC_IF_MOD( 1543): codec_close: freed apt-x encoder


    That would seem to show that the aptX codec is being used. The sound quality is also very good, though I can't honestly say if it's better than the sound I was getting when using the earphones with my Galaxy Nexus.

    great, thx, makes sense that it would since the nexus 10 has apt-x support as well.
