Beep sound with video recording

Hi garja240,

Thank you for participating in the Apple Support Communities. If we understand correctly, your iPhone is making a beeping sound when recording videos that can be heard when you play back the video. We recommend restarting your iPhone as this can refresh iOS. You'll also want to make sure you have the latest version of iOS: Update your iPhone or iPad. If you're using a paired audio device, remove it or unpair it and test for this behavior. To unpair a Bluetooth accessory, go to Settings > Bluetooth, find the device you want to unpair, and tap the More Info button, then Forget this Device.

Take care.
