I am having this problem with my phone. Every time I set the phone ring volume, after a while (30-60 minutes) I suddenly hear my phone vibrate and then it automatically on its own goes into silent mode with silent icon appearing in the top bar. It is very annoying to keep checking my phone to see if it has not gone into silent mode.
Any idea what may be causing this. I cannot find in anything in the settings to enable or disable this.
