my android phone has a nagging "security update" popup that I cannot delete. I don't update so it stays with my phone all the time (it takes a huge amount in the pause screen), i have to deny the updates each time i restart my phone (which doesn't happen often). Nonetheless, it's true I can still use my phone (and the appstore)... huh, now that I take a closer look at this annoying update it appears to be from samsung not from google.
