How do I fix a straight line in the front camera of my iPhone?

There is a strong possibility that the sensor is compromised. I'd try with some other camera app, such as ProCam ( https://apps.apple.com/mx/app/procam-pro-camera/id730712409 ). If the glitch persists then there is damage and you will need service.

Then the sensor has probably been physically damaged. Make an appointment at the Genius Bar of your local Apple Store.

First, try ➢ this helpful guide for a possible solution.

If that doesn’t help, then Force your iPhone to restart:

1. Press and quickly release the volume up button.
2. Press and quickly release the volume down button.
3. Press and hold the side button until you see the Apple logo (this might take longer than 10 seconds).

If that was too difficult, then simply ask Siri: "Restart".

If that didn’t help, then I recommend service.

Service Checklist:

You conveniently skipped the 2nd half of my advice to schedule → camera service.

Good Luck! 👋🏼😉

Night mode use the 1X (24mm equivalent) lens. If you’ve go outdoors does it still appear? Does it appear if you select 0.5X or the telephoto lens?
