iOS: Images capped at 1920x1080 resolution

[anth0]

Describe the bug
All the photos I take with my device (iPhone 8 iOS 13) end up as 1920x1080 images even though the device has a 12Mpx lens hence can produce photos up to 4032x3024.

To Reproduce
Simply set capture options as follow :
CameraPreviewPictureOptions = {
quality: 100
}
I've tried also to pass height and width parameters but they don't seem to be taken into account as the result is always the same.

Expected behavior
I'm expecting to get the best photo my device can take, especially when setting quality to the max value.

Smartphone (please complete the following information):

• Device: iPhone 8
• OS: iOS 13.6
