This is my second galaxy s4 and have just started to experience no notification sound, no ring, no alarms in between use, only works after restart. Anyone deal with this before?
If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.
Thanks for the reply B.Diddy. I'll try to leave it in safe mode and see if the problem is with an app. The problem is that this happens randomly, so the phone will work fine and then out of no where the sound will just stop working. I only notice it not working when I see that I've missed a call or text etc.. Next time the sound isn't working I'll have to plug in my headphones and test it.
