i was at Fosdem too, i did not read into the topic linux on phones and i was dissapointet that there are soo few apps (speach linux phone app ecosystem) and that the user experience other than on android based custom roms is not that great. I was still hyped seeing the jolla phone and overall the attention to that topic

did you tried it, what is the experience like?

Do you have any suggestions for a better/open-source alternative?
