PostmarketOS gets you pretty close to this: boot alpine Linux, with more or less everything working. Even if the screen and/or GPU acceleration do not work on that phone, that would be plenty to replace a Raspberrypi. I've been thinking about this quite seriously, and for now I see a few pain points: - Some phones (looking at my daily driver, a Galaxy S4) do seem to allow disconnecting the battery from the charging circuit, which could lead to issues in the long run - Ideally, you'd want to connect a USB hub over USB OTG (wired Ethernet, USB storage, real keyboard). I have yet to try charging the phone at the same time, although I think some cables enable this.
