So, I stopped AlienDalvik about 9 hours ago, disabled the start on boot option and re-booted. Battery drain, as shown by system monitor, was back down to normal and idle CPU was at about 12% - no browser windows opened at all. Started Aliendalvik again and … first think that happened was that APKPure started up and came to the foreground and then a native browser window opened selling ‘meds’ (pills to us Brits!).
Interestingly in SFOS Settings/Apps for APKPure the ‘Allow background services to start on bootup’ was not enabled - so how did it load itself???
Now deleted APKPure, so we’ll see if any native browser windows show up overnight…
This is a damn good question … Do Android Apps under SFOS Aliendalvik get to do anything they want?
