That would be great!
I’m currently using a non-official ROM found on XDA: https://forum.xda-developers.com/galaxy-s5-mini/development/unofficial-xenonhd-7-1-t3604837
Here’s the entry point for all S5 mini ROMs on XDA: https://forum.xda-developers.com/galaxy-s5-mini/development
There seems to be mostly (only?) unofficial ROMs… hence no or little updates. Would be great to see a /e/ ROM here!
