Causes of Crackling Speaker Issue

The crackling sound from an iPhone's speaker can be caused by a variety of factors:

1. Software Glitches: Sometimes, the crackling issue might be related to software problems. This can include bugs or issues with the iOS version that is currently running on the device.
