I've the same issue,
and the problem was the forced autofocus of camera that i've used.

I've the same phone and the same iOS.

In particular,

device.focusMode = AVCaptureFocusModeAutoFocus

used in this snippet:

- (void) forceFocus {
    NSArray * devices = [AVCaptureDevice devices];
    NSError * error;
    for ( AVCaptureDevice * device in devices ) {
        if ( [device position] == AVCaptureDevicePositionBack ) {
            [device lockForConfiguration:&error];
            if ( [device isFocusModeSupported:AVCaptureFocusModeAutoFocus] ) {
                device.focusMode = AVCaptureFocusModeAutoFocus;
            }
            [device unlockForConfiguration];
        }
    }
}

If you use something like that, try to remove the autofocus.
Should solve the issue.
