Hello.
My battery died on Note and while checking what is inside I made some photos if anyone would be interested.
There are some connectors that has nothing attached- one 3 pin connector and another 9 pin at the bottom. It even has a plastic cut out for it (just not on the outside shell). There is plenty of space for A sd card slot and headphone jack. I think that Onyx wanted to fallow current trends. Also the screen itself is not rounded up in the corners- its just the shell that hides the corners of the screen.
