I have seen this as well.
I don't think it is a false positive either, because i've had a fake amazon application appear on my screen that went nowhere at the login, multiple login requests from my phone for my main email at weird hours, and INCREDIBLY slow everything on my phone all of a sudden.
I have factory rest twice (both in different ways), and the second time almost got stuck rebooting. Did another scan, still there.
It could be coincidence on my end, but I pay really close attention to everything on my phone, and there has definitely been a change on it (s7 edge) .
I hope this gets fixed, I don't feel safe doing much on my phone, not even texting or calling.
