I am here today to share my idea for a mobile operating system, perhaps a derivative of android or its entirely own thing.
The operating system would have a very simple interface. A background (of the users choosing), and in the foreground would be the users apps. The apps would be circular and settings would be simple to understand and wouldn't take up a zillion pages.
It could go 2 ways as well, 1 way being what I already stated and the other following more of a feature phone where you can't put apps on it, you only have the basics but with a touch screen device.
This operating system would be designed for absolute simplicity in every way as it is primarily targeted at old devices with limited power (or just not as much power as today's devices), it could also be placed onto new devices if there became a demand for it but it is primarily targeted for old devices.
I'd attempt to develop this myself but admittedly I have very little knowledge when it comes to code.
