there is two virtual key apps in this package, the one on the screenshot: yes can be usefull on N8.If the N9 power patch is apply you need a (back arrow) key some how. The hardware key does bring the home screen but does not get the previous sub menu up to is rooth and let it open. Of course there is no green and red hardware key on N9 but the shutter key(camera light press) and the volume keys can be re-mapped to do as required if needed.when re-mapping it wait the input of the desired function, openning the menu setting of the app from the bottom reveal option for special function witch include a left soft key witch is needed to go back.disregars the compatibility warning when installing it wil work fine on N8.
