Phantom Notification Sound
For the past three days, I've noticed my phone making a notification sound but then there's no notification text in the status bar. It seems to make it at random times also. I have notifications turned off in Gmail, which is the only email client I have installed. I also checked notification settings in the calendar and tasks apps, along with some of the other apps I use frequently. Has anyone had a similar problem or have any ideas?
Since I just started noticing it a few days ago, I thought I would also try to check to see what apps I had recently updated (I haven't downloaded any new ones recently) to see if something changed in an update.
