Also - adding to the puzzle. No notification of email shows on my screen when this happens. And the notification sound that I'm getting is not one of the sounds that I can choose in sounds menu.
I'm hoping that you've been able to stop the notifications that've been happening while your phone is on silent. If this is still going on, please let me know what baseband version your phone is running on.
Have you tried power cycling the device?
It sounds like your phone has a mind of its own, magenta4432479! What baseband version are you currently on?
- From the Home screen, swipe up on an empty spot to open the Apps tray.
- Tap Settings.
- Scroll down to and then tap About device.
- View the software version in the Baseband field.
Did you still need some help with this? If so, what's the email client you're using? There may be a setting within the email app (like Gmail) that'll allow you to disable to the sound. It's separate from the phone's main sound settings. Please give us a reply back and let us know. Thanks.
