Yup, chinese or russian apps usually have more malware as well. Poorly made apps with security issues. I see folks saying well google collects data too and all that. These damn chinese apps are way less secure.
All those face apps are made in china too, collecting image data and then providing ads based on your pictures, they can even determine what is your location if you take many images outside and then give you location based ads.
When you use a smartphone an ad block is a must, for the very basic protection, also disabling internet access to apps that really don't need it, but were actually allowed to use! Like for example keyboard app, you don't need keyboard app accessing internet, but it's made for better machine learning experience
