Trojans in firmware of (not?)well-known Android mobile devices

[Elixer]

If you have one of these (possibly others) then you have a trojan in the firmware:

It is known that cybercriminals generate their income by increasing application download statistics and by distributing advertising software. Therefore, Android.DownLoader.473.origin and Android.Sprovider.7 were incorporated into Android firmware because dishonest outsourcers who took part in creation of Android system images decided to make money on users.

Yet another reason people should be allowed to install their own firmware without having to root their devices.

I've never heard of a thing on that list. Aren't those all just cheap Chinese phones? (Does the term well-known really apply here?)

I came for the well-known Android devices but have yet to find them.

True, just copied the title from that page.

Fixed it.

I don't recognize any of those devices.
