Google’s latest revision in the Android version that is the version of 4.2 Jelly Bean, was a latest app verification service.

Jiang utilized 1,260 samples of malware deriving from 49 different families in the analysis and among those, Android 4.2 recognized only 193. Then again he tested a sample which was taken from a random family of malware with some famous available anti-virus scanners, like AVG, Symantec, ClamAV, Avast, TrendMicro, Fortinet, Kingsoft, F-Secure, BitDefender, and Kaspersky. The detection rate ranged from about 51.02% up to 100%, meanwhile the Google’s OS had a recognition rate of 20.41%.

Jiang was not analyzing the whole operating system, he was analyzing a feature known as app verification in Android 4.2 which try to keep away the users from harms at the time of installing and downloading new apps. If this verification test detects malicious code, you will be provided with a warning or a total block from the installation based on the severity.

For the first time, Android 4.2 gets support to multi-user access to tablets and smartphones, using which users can make various user accounts and utilize the device as independent users with distinct IDs. It seems that even this feature is like buggy. It looks only the OS permits users known as the device ‘Owner’ to use Google Talk, whereas other users will get a message of error stating that this version of Talk can be accessed by the device owner only. This may be because of the present Google Talk app.
