I am using android-x86 with virtual box . It comes preinstalled with google play store and other services but i can use that iso file with VirtualBox as only as tablet and therefore cannot download some apps from the play store . I tried changing the resolution but that dont make the emulator screen look like an android smartphone machine. How can i use the android-x86 image file as a smartphone.
Genymotion is based on VirtualBox and emulates phones as well as tablets.

Also - the new Genymotion (2.x) devices are rooted out of the box.
