please add the HTC Desire C [Golfu (GSM)] to the list of supported devices.
I very much like small and old devices, but sadly there is no chance for it to have current /e/ versions built for it. It has 512M memory and a 4G flash, the last unofficial alpha state cyanogenmod versions built for it were CM 11+12 (Lollipop).
Those specs are not nothing, a very minimal AOSP could probably run.
I think PostmarketOS is a chance for the device class, but you’d need the device hardware best be supported by the mainline linux kernel and those pre Snapdragon 410 devices are not very well supported.
