The Institute IMDEA Networks and University Carlos III discusses this issue in a study of more than 82,000 apps and 1,700 devices.

More than 82,000 pre-installed apps in about 1,700 Android devices manufactured by 214 different brands have been analyzed by the Institute IMDEA Networks and University Carlos III Madrid.

And, as a result of this study, it has been verified that the model permits the software of Google and its applications allows the monitoring and the collection of personal information at the system level. In addition, the end users would not be aware of it. In particular, were discovered more than 4.845 permissions “owners or custom” by the actors involved in the manufacturing of devices, and that circumvent the permissions model in Android to access data without the authorization of the user.

Regarding the pre-installed apps, have detected more than 1,200 companies and more than 11,000 third-party libraries, many of them linked to advertising services and monitoring commercial purposes.

The authors of the study also warn that the software with system privileges it is difficult to remove by non-expert users. These pre-installed apps are running good part of the occasions without the possibility of uninstallation.

To analyze the behavior of the applications, he saw a proportion notable of them were potentially malicious or had unwanted behaviors. Here enter from malware and trojans generic pre-installed software that facilitates the fraud. And in terms of the information that is offered when you start a new terminal, lack of transparency both on the part of the apps like Android system because it shows “a relationship of permissions different from the real”, which impairs decision-making capacity.
