react-native-vision-camera: 🐛 iPhone throws an error when capturing a photo with flash

What’s happening?

When I call Camera.takePhoto and pass { flash: 'on' }, the camera throws an error every time. When I pass { flash: 'auto' } the camera throws an error if the surroundings are dim enough that flash is required.

On the first attempt to take a flash photo after activating the camera, the flash will briefly turn on before the error is thrown. On subsequent attempts, the error will throw without the flash turning on at all.

When I pass { flash: 'off' }, (or { flash: 'auto' } in well-lit conditions) photo capture works as expected.

The error is:

[capture/unknown: Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSUnderlyingError=0x285b17600 {Error Domain=NSOSStatusErrorDomain Code=-12780 "(null)"}, NSLocalizedFailureReason=An unknown error occurred (-12780), AVErrorRecordingFailureDomainKey=4, NSLocalizedDescription=The operation could not be completed}]

Reproduceable Code

const photoOptions = {
  qualityPrioritization:
    photoQualitySetingsMap[photoQualitySetting],
  enableAutoStabilization: true,
}
if (device.hasFlash) {
  photoOptions.flash = flashSettingsMap[flashSetting]
}
           
const photo = await camera.current.takePhoto(photoOptions)

I found a reliable relation to failing to capture photos with flash ON. The test device is iPhone Xr 17.2.1

In format, there is autoFocusSystem value. It can be phase-detection or contrast-detection. If I use a format with contrast-detection and flash ON it will error. If I use a format with phase-detection and flash ON it takes a picture.

https://react-native-vision-camera.com/docs/api/#autofocussystem ( definitions are taken from apple docs )

My guess right now is contrast-detection is slower to auto-focus by definition so

  1. It might be incompatible with flash ON or
  2. Race condition.

Btw.; I just merged this PR where you can query for phase-detection https://github.com/mrousavy/react-native-vision-camera/pull/2455

Oh nice research, thanks for getting back here! I’ll try to take a look with that info
