I had a meeting reminder pop up and I dismissed it. But since then the reminder alert has been going off continuously. It just won't stop. There is no message on the screen for a reminder but the alert is still going off. I restarted the phone and it still won't stop. Has anybody else encountered this? How do I fix this? Thanks in advance. Edit: It's the same alert sound you hear when you plug in the phone to recharge. I had the same issue once when recharging but that was resolved by unplugging and restarting the phone.
