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, Kate The Great and Terrible.
