I just want to mention this if it hasn't or has mentioned before.

When you capture a picture or video, the preview shot is shown but when half press the camera button the preview mode doesn't revert back to camera mode. Original camera app does that for quick snapshot.

Also another thing is the colour of the new camera Ui is seems to be a bit washed up when the object is bright red or orange. It change the colour from red organe colour to purple when there is too much light reflect back from the fruit (strawberry, apple) or object.

Not sure why it did this but I'm just raising this incase it can be fixed in the future
