I should also consider the technical feasibility. iOS is built for ARM architecture, similar to some Android devices, but the kernels and other system components are different. Running iOS on Android would require a significant amount of porting, which isn't publicly available. There might be some unofficial projects, but they are unlikely to be stable or legitimate.

The direct download and installation of iOS 9 on Android is mythical .

iOS runs on the XNU kernel; Android runs on Linux.
