Why does my iPhone make a random noise?

Greetings kyreekk3,

To help troubleshoot possible software issues with your iPhone, ensure the device is updated to the latest version of iOS, and test after restarting the device. Check out those steps here:

• 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."

If further assistance is needed, please describe where the noise may be coming from, along with any further description of the noise that you can provide. That may help to isolate the behavior and allow the community to respond with steps that could help with a resolution.

Kind regards.
