After I updated iOS to 15.3.1, there is an unusual rattling noise whenever the phone vibrates. The phone never fell or damaged. What can be the reason for this as it was not observed in any if the previous iOS versions?
iPhone XR, iOS 15
It surely is not due to the iOS update, because if it was so then millions would have it.
If you have either dropped the device accidentally or exposed it to liquid or used it beyond acceptable temperature limits then…
