We're working on it with postmarketOS [0]. A lot of the issue is that most devices have poor, if any, mainline kernel support. That means you have to rely on the downstream vendor kernel, which is almost always hopelessly out of date. (For instance, the downstream kernel for my OnePlus One is at 3.4 from 2012.) Besides just being out of date, the vendor kernels require binary drivers and Android-specific services to use a lot of peripherals. For instance, the graphics driver Freedreno is compatible with my OnePlus One's GPU. However, Freedreno isn't compatible with the version of KGSL that the downstream kernel supports. That meant that my only options, if I wanted hardware-accelerated graphics, were to use Halium or mainline my device. That's not even getting into bringing up WiFi, LTE, and actual phone capabilities, which are still a ways out as far as open source software is concerned.
