i phone is making random noise

Hello Ann_crane,

To help troubleshoot, ensure iOS is updated, and test after restarting your iPhone. Those steps can help clear up unexpected behavior:

• Update your iPhone or iPad - Apple Support
• Restart your iPhone - Apple Support

"How to restart your iPhone X, 11, 12, 13, or later

1. Press and hold either volume button and the side button until the power-off slider appears.
2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."
