Galaxy S7 edge - How do I use a sound downloaded as part of a theme? I want to use the sounds I have downloaded as part of my theme (Blue Polygon) as my ringtone and alarm sound. However, it is not in the selection of sounds when I tried to change it. 

Please advice. I have no root access.
I have asked the developers and found out that this is a bug caused by setting one or more of the sound settings (notification, ringtone and volume) to silent.

To fix it, follow these steps:


Start by going to Settings - Themes, select the theme named "Default", and then apply.  
After this, go through all of your settings and make sure nothing is set to Silent. 
Once this is verified, re-apply the theme and it should be working.
