Cubot Note S Problem

[Rochi_Senpai]

So i bought Cubot Note s and after 2 months it tried to install apps called "Airplane" and "Subway" by itself. I tried to use Malwarebytes but it does not find anything. And it keeps switching apps on from unknown sources even when i turn it off. How do i get rid of it?

there must be a package installed with system privileges that do that.
try to find out which of them does that.
