I'm setting up a linux box to use with a smart tv using a closed network.
I also want to be able to use me phone (android kernel 4.9.112) with the tv 
(samsung 2019 model). Anyone know of a screen mirroring /casting apps for 
android phone that are FOSS/GPL  and safe to use (as in spyware free).
If the apps as a linux OS counterpart that would be a plus.

Thanks in advance your help and patience,
