I just installed the 5.01 Lollipop update on my Verizon Note 4. After the update the Notification sound is the default sound, the whistle. I have changed it to another sound on my SD card and it plays fine, but when the notification comes in it still plays the whistle tone. Any ideas? I have tried changing it in the sounds/notifications menu and it did not take. I have also verified the tone is available on the SD card in a folder called Notifications and is playable. I have done a factory reset and it still is stuck on the whistle as the default notification.
