Testing with iPhone XS, sessionPreset is set to photo. The picture resolution is usually 4032x3024, but sometimes it is taken at 3088x1938. What's the reason?

Below is my code.

let photoSettings = AVCapturePhotoSettings(format: [kCVPixelBufferPixelFormatTypeKey as String: Int(kCVPixelFormatType_32BGRA)])
photoSettings.isHighResolutionPhotoEnabled = true
photoSettings.isAutoStillImageStabilizationEnabled = true
photoSettings.flashMode = self.flashMode
self.photoOutput.capturePhoto(with: photoSettings, delegate: self)

What have you set your AVCaptureSession preset to? – adamfowlerphoto Jan 10 '19 at 09:50

Your 3088x1938 images aren't from the front camera by any chance? – adamfowlerphoto Jan 10 '19 at 20:09
As you said, I got it from the front camera. Thank you. – 유병호 Sep 20 '19 at 04:44
