I just switched from an M8 to an M9 and so far so good. Except, out of nowhere, it started setting off the Notification sound with vibration about every 30 seconds. I figure I changed something by mistake but I can't figure what. I checked in "Settings" and "Notification Reminder" is definitely off. I can silence the sound, but I can't find a setting to turn off the vibration until I find the app responsible. It's killing my battery. Any suggestions would be appreciated. Thanks in advance.
