I have made some experiments and IMHO it is impossible.
Use canvas and image sprites instead of screen background picture to control the aspect ratio of elements.

How you make this? The only solution I made is to edit the background picture in painter to have the right resolution...But this only work for my phone if fone has diferent resolution there will be no circle..
