Noobs question here. Due to my country's vizarre VoLTE standard, I have to root & install Magisk if I want to activate VoLTE in Pixel series. (https://github.com/nooriro/volte-kr-crosshatch) I know this is not compatible with GOS securiy policy, but if I unroot & delete magisk, can I install GOS after that? Or, should I give up VoLTE if i want to use GOS?
