End your frustration and get a Topping E30 for $140. Sell the W4S.

+1 for drrsutliff comments.

Also, the user's manual indicates the Wired 4 Sound DAC 2
uses proprietary software drivers that are specific for Mac or Windows OS installations.  Although there may be work-arounds, a stock software driver likely doesn't exist for an Android OS.

BTW, you may want to check to ensure you are using the latest W4S drivers for your PC installations, and not some Microsoft-assigned default, so that you are taking full advantage of the I2S features on this DAC.

Also, it seems there are some interesting hardware upgrade options available from the Mfr. for this unit.

As for controlling your music, playlists, etc. remotely from your phones, there are many good options.  I am using JRiver installed on my PC, with the free app JRemote running on iPhone and IPad (but also has an Android version).  JRiver will recognize and support the W4S drivers as it does for my Ayre Acoustics drivers.
 Good luck.

I have had about 8 emails from EJ at W4S. TY Sfar and jjss, Like end ej said in the end that he wasn't sure. What  drrsutliff said makes seance. Maybe i need a different usb cable. I bought a usb B to usb C cable off amazon and it still didnt work. The laptop was released in 2013 the note 9 released 2018 so i would think the phone more advanced than the DAC soo still what  drrsutliff says about the cable makes the most sence to me. I have tried different cables including ones that came with the phones... 
  I probably responded incorrectly here but I didnt see where I could make a fresh post only a reply

Are  you using a basic phone to USB cable?  That won't work.  You need an OTG cable, on the go cable.  It looks like a normal micro to usb but it's not.  Amazingly cheap fix.
