cracking sound while video recording with camera

Hi abdulwahidfateh,

Thanks for coming to Apple Support Communities for help today. It sounds like you hear a crackling noise in recorded videos.

What you are describing could indicate a mic issue. Have a look here: If the microphones on your iPhone aren't working.

Is there a similar issue if you use the speakerphone? If so, it's likely service will be required.

Have a fantastic day!
