To be candid with you, installing Android OS on iPhone OS will be like 17 Goliath’ fighting a small David; an insurmountable task but mirroring the OS on the iPhone screen is doable. Lee devised a few new Android components that allowed streaming the screen contents from Android to iOS. He tested this concept with a Nexus 5 before building the standalone case.
Lee built the case version from a Lemaker HiKey development board. This device has a Kirin 620 SoC, 2GB of RAM, and 8GB of on-board storage. It’s sufficient to run Android 6.0.1 without being too huge. Lee was able to 3D print a case for the board and battery with a Lightning cable snaking out the bottom. When plugged into an iPhone, he can launch a custom app that listens for the case. Upon connecting, the hardware in the case streams the full Android experience to the iPhone screen.
