@alaskalinuxuser I'm very impressed to see that Ubuntu Touch works on the Furiphone FLX1, which is also Dual Boot! 4G calls (VoLTE) are now supported by Ubuntu Touch, but this has to be ported specifically to each device. This is the implementation of an IMS technology plugin in the Ofono module. (I don't know what the situation is with the FLX1, but it must be feasible). Out of curiosity, do you know which update channel the device depends on? Will it be upgraded to Noble as well?
