my camera stop working in facetime but after update but works in face book messenger

Hey there, jayboyd0831.

It sounds like the camera on your iPhone 7 isn't working for FaceTime but works fine when used for other apps, like Facebook Messenger.

Does this issue only affect the front-facing camera? If you start a FaceTime call do you get any errors about the camera, or is it just black? Does it work if you switch to the rear-facing camera? If you open the Camera app, do both the front- and rear-facing cameras work as expected?

Go ahead and start with the steps listed here.
