Check the result

  • Save local ringtone output and any call-only pattern. For call-only trouble, include reception/location when speaking with the carrier or Apple.
  • Persistent silent ringtone output or a dimmed speaker control needs Apple assessment.
Stop conditions
  • Stop using and charging equipment with swelling, casing separation, smoke, a burning smell or suspected battery damage. Do not open or press on it.
  • Set damaged accessories aside. Do not open mains adapters or force connectors.
  • Do not erase, reset, flash firmware or bypass a lock as a default diagnostic step.
