Since updating my system to Nougat two weeks ago my phone has been seemingly stuck on vibrate mode. Even though ALL notification settings are on high volume, I have missed calls, alarms, text notifications, anything that makes a noise it only vibrates. A small fraction of the time I'll actually get the call sound or text notification, but more times than not it doesn't work. I've missed important phone calls and alarms for work in the morning because of this. The phone has not been wet, damaged, or subject to extreme conditions. I know I'm not the only one with Nougat issues, as the forums are going crazy, however I've yet to find a solution for this.
