After checking the website. it does sound like Graphiene OS. Does it at least allow you to use the Google Play store and treat it like an app thats isolated from the rest of the phone? with Graphiene OS. how it does it is have it located on a second menu and only allows it to talk to the servers as needed and not all the time. basically an isolated app that only works when used. do you know how this OS works on this level. this video will explain the reasons why I want Graphiene OS on Fairphone in detail. if you have any info on Calax OS and how it operates would be helpful in this thread.
