Intermittent Hum
I get an intermittent hum while using phone. It sounds like the hum associated with the vibrate mode. Spoke with wireless carrier Verizon and they state it is not caused by their network. Very annoying.

Hey robagail,
When troubleshooting noise while using the iPhone 4S, the following article provides the most relevant information:

If this happens only when using the receiver, do the following:
- If you have a protective case on the phone, either ensure that the top microphone next to the headset jack is not covered or remove the protective case completely.
- If you have installed a protective film on the display, either ensure that the receiver is not covered or remove the film completely.
- Check the receiver mesh; if it appears blocked, use a clean, small, dry, soft-bristled brush to carefully and gently brush away any debris.
- If the audio issue happens only in one location, try another location.
- Try restarting the iPhone.
- If restarting the iPhone didn't resolve the issue, update to the latest version of iOS.
- If the issue persists, visit the iPhone Support Page for more troubleshooting and service information.
Thanks,
