Improved camera samples? topic

I am considering buying a Mini and I would like to ask, if there was a camera update thats targeting the actual photo quality? I red that there was some functions update, but did this improved the photos? All sample photos I saw on reviews were not much good, so I am interested in this.
Thanks
