Major issue. No notification sounds. I have tried all the stuff listed on here. They will work sometimes when I have the phone open but not always. Usually just a short vibrate. 2 things that are weird and has nothing to do with all the setting people suggest check is that when I access the menu to choose a notification sound and I switch between sounds I hear nothing. My son's same phone plays a preview of each sound. Also when I change the volume on the notification sound I hear nothing unless I adjust the volume on the media or ring tone and then switch back to adjust the volume of the notification and it plays once and only once no matter how many times I move the adjustment bar. Please help!
It honestly sounds like it could be a software issue, I'd recommend visiting your local uBreakiFix for a software reflash: https://www.ubreakifix.com/locations
