Totally a game changer for when you need to record yourself lip-syncing or doing some choreography. I know this works on iPhones 10 and up.
Step 1: Change your camera to PHOTO instead of VIDEO. Change the aspect ratio by clicking the little arrow at the top.
Step 2: Go to your music player and play music.
Step 3: Go back to the camera in PHOTO and hold the button like you are going to take a picture. But HOLD IT and drag it to the right to the lock icon. That will lock it in record. I know, crazy right?!
