KaiOS – A Smartphone Operating System
I'd really like to see a truly open alternative on the mobile space. The biggest issue is the hardware. It's just not standardized and there's no incentive to do so. It's really preventing the way Linux took off on developers desktops back in the late 90s/early 2000s.<p>FirefoxOS and Ubuntu Touch looked promising, but they lacked good hardware to run on. I'd really like to try Plasma, but I don't like any of the devices it supports.<p>PostmarketOS is just a way to turn an old phone into a Raspberry Pi type device, but maybe that's the first step in a truly unified mainline kernel for all mobile devices.
