Hello, I've read USB OTG was greyed out with FW1.6.
Is it possible again with firmware 2.x?

I have a Samsung J5 mit OTG-Hub.
I can switch audio from local to  'fiio_...._DAC' and X3 shows 'USB DAC' but there is no signal processing (0kHz/24bit, not 44.1kHz/24bit)
Can you please help?

Hello,
that is very bad news.
I tried to downgrade from 2.0 to 1.4, but that failed "too old".
So i first downgraded to 1.6 but downgrad ti 1.4 still not possible.
I want to use the X3II as USB-DAC for my new Galaxy J5 android 6.
Is there any chance?
Sincerely , u

Yes, the 1.4 is too old, the remove the otg function means that it can not read the external removable drive via the USB jack. It doesn't mean that you can not use it to be the dac to your smartphone.

However, we can not guarantee the dac to your smartphone. X3ii's dac is designed for PC. It is not the otg issue.
