I could implement the filtering by Android version. I already research that info. You can see it when you click on the phone. I did not add a filter for it as it might be somewhat misleading. Because it might be possible to upgrade the phone to a newer version.
As for phyiscal size, usb-c and headphone jack - I would have to research that data. All data on Product Chart is reasearched manually. So it takes quite some work to add another parameter.
