Hi, we would like to inform you that we have dedicated sounds assigned for each category, you must manually change the ringtone or notification tone.
By changing anyone will not affect others.
For example: If you change sound for notification it is applicable only to messages or any other apps notifications not for calls.
If you did not get your answer.
We kindly request you to write back to us.
Click on the Notification Category you want to change > Click on Sound & then you'll see a list of all the sounds you have available, including the ones you Downloaded from Zedge.
Go to Settings > Notifications & take a screen shot of what's there. You should have Android System Notifications & if you Click on it, you should then see Categories.. I would think that that's there, regardless of the device.
