Hi prisonmikee!
Thanks for following up and testing to see if this issue occurs when recording a voice memo. You might want to check and make sure that your iPhone is running the latest iOS version. If any updates are available be sure to backup your iPhone before installing and once completed test creating a voice message for improvement once updated.
