I may have pocket changed a setting... but for some reason, when my phone is set to Vibrate Only, it will ring for incoming calls. I've looked through the OPTIONS menu bar and I have the following settings:
Vibrate ONLY setting:
Ring Tone volume = SILENT
Visual LED = ON
Tactile Alerts Vibration = ON
Is there something I'm missing here? Why is my phone ringing on VIbrate?
Might be a software glitch. Try switching your Ringtone volume, save it, come back and change it back to Silent and restart your phone by removing your battery or press and hold ALT+aA (Caps)+Del for a few seconds.
