h1. GNU/Linux distributions

h2. Halium

Some GNU/Linux distributions like Plasma Mobile, LuneOS, Ubuntu Touch use libhybris through the "Halium project":https://halium.org/ to reuse proprietary Android libraries

h2. Mer

* Mer uses ofono for handling the modem
* For OpenGL it's not clear if they use nonfree drivers. It would be worth looking into it. Their stack seem to be able to use free implementations as well as nonfree implementations.

See the "Mer architecture":https://wiki.merproject.org/wiki/Architecture for more details.

h2. PostmarketOS

"PostmaketOS":https://postmarketos.org/ is probably not using libhybris at all and is instead working with upstream and probably doesn't depend on nonfree libraries

h2. Replicant strategies

Replicant is currently involved with upstream GNU/Linux, but it would probably be a good idea to collaborate more with  distributions that don't depend on libhybris.
