The processors and peripherals aren’t as uniform as they are on computers. Each SoC has a different set of components, which need drivers and custom set-up mechanics and they’re often only shared between the chip designer and phone manufacturers. A lot of complicated reverse engineering is needed. And that’s often not worth it as there are many different phones on the market and they’re short-lived devices. So we end up in the current situation where we don’t have the operating system foundation / drivers available to the community to build upon.

There is Linux on phones. A modified Linux kernel runs on every Android device. Just the userland is an entirely different one. And Linux isn’t there yet with the desktop and apps. A lot of features are missing, power saving, delivering messages while sleeping and doing background tasks while saving power in the pocket… It’s kind of a chicken and egg dilemma. We’d need some popular Linux phone so people are motivated to tackle the remaining software issues for a mobile ecosystem. And we won’t get one unless there is some good software so it can be marketed.
