I don't have a phone that is compatible with graphene os, and also I don't have money to buy a compatible smartphone. Is there any way to create some kind of container with linux for example. The main issue that I have is that apps can view/check ports on loop and chech if i use vpn. I know that I can install a sort of linux container on android with termux, but will it be secure? If someone will unlock the smartphone, will he be able to read the content of this linux container
