alt Hacker NewsWhat, exactly, is sandboxed Google play prevented from accessing? Can I feed it a fake location or disable location access? Is it prevented from running in the background 24/7? Can I force it and just it through a VPN? Or is it just blocked from accessing apps and files that aren't in the sandbox? There are many such questions and all could be considered "sandbox".
Sandboxed Google Play receives no special access at all, so you can deny it all permissions if you want, but you should grant network (and maybe notifications) permission for it to actually function.
