Ok I know that this project sounds ridiculous and it is. Android is not meant to be put into a stamp sized display. But lets be honest: It would be really cool to have a working old Phone with modern technology. So I am still going to do it. As a little taste here is how it would look like if you just start up Android on a screen that 'big':Not really usable to be honest but I am trying to build a menu that can give you all the phone functionality I want. Or maybe I stick to Linux and build a GUI for it. But where is the fun in that?
