When change the framebuffer resolution by calling

```
Screen.setResolution(1920,1080)

```

`Screen.currentResolution, Screen.width, Screen.height` reports back the new resolution 1920x1080.

`Screen.resolutions` gave me empty array (tested on real android device).

I am unable to get back the original resolution which was a native resolution of the device. Do I have to remember the native resolution or is there a way to get that through unity API ?
