As the title goes, my galaxy s8 keeps charging each dac I use be it goDap X or any iFi device old or new. I know the trick to turn dac on first then plug but it does not seem to work.
I am sure its not the phone, as I'm getting 2 days of use without peripherials.
If I was to get custom usb otg without the charging line built in, would the phone still detect DACs?

Thanks in advance, Im sure there are many samsung users here that run into this issue.
