Notification Settings Randomly Changing
I have a Blackberry Passport and every time I set my phone to Silent or Vibrate, it is constantly changing itself back to Normal or to Vibrate or some other setting without me doing anything. Even if my phone is just sitting on my desk and I haven't touched it after I just set it on silent, five minutes later it will be back to Normal and ringing.
Any ideas what is causing this? I work in a business that requires my phone to stay silent when I set it to silent.
