I had the same problem this morning. I woke up with no notifications and then I wake up my phone and boom, 2 emails, a shop Samsung, MLB At Bat. I have no battery saving options on, no do not disturb nothing.
I was gonna take it into Verizon to maybe get a replacement if my phone was damaged but I know they will just tell me to do a factory reset and come back if it still happens. But since others are having the same problem it's good to know it's not damaged
Is anybody else having call volume problems through the earpiece and or on speakerphone after nougat update? Some calls it's loud with both options, sometimes I can barely hear the phone ring or people talking on the other end.
