I was trying to find information on how to assign a custom sound to my text notification.
I saw several posts regarding custom notifications for text messages, other than the ones Verizon gives you. This worked for me on a Commando 4G LTE.
I plugged into my computer with the USB cable.
I put the files I wanted to use in the Notifications folder on the internal storage.
These were all .WAV files, so I don't know if other types will work.
Voila, when I went to assign sounds, the files were there.
If your Looking for Like a Special Ringtone for Like a Message Alert, Email, that sort of thing) Look in the PlayStore on your Phone and Find ZEDGE they have some Really Nice Ringtones, Notification Ringtones and Wallpapers and they don't Cost anything, Give it a Look and Enjoy b33
